A grinding wheel is a uniform cylinder with a radius of 7.20 cm and a mass of 0.350 kg <3 of 3 Constants Calculate its moment of inertia about its center. Express your answer to three significant figures and include the appropriate units. Calculate the applied torque needed to accelerate it from rest to 1750 rpm in 6.80 s. Take into account a frictional torque that has been measured to slow down the wheel from 1500 rpm to rest in 62.0 s Express your answer to three significant figures and include the appropriate units.
Answers
Plugging in the given values, we have I = (1/2)(0.350 kg)(0.072 m)² = 0.055 kg·m². This is the moment of inertia of the grinding wheel about its center.
To calculate the applied torque (τ) needed to accelerate the wheel, we use the equation τ = Iα, where α is the angular acceleration. The initial angular velocity is 0 (since the wheel starts from rest), and the final angular velocity is (1750 rpm)(2π rad/min) = (1750)(2π/60) rad/s. The time taken (t) is 6.80 s. Using the formula α = (ω - ω₀)/t, where ω is the final angular velocity and ω₀ is the initial angular velocity, we can calculate the angular acceleration. Substituting the values into τ = Iα, we can find the applied torque.
The frictional torque (τ_friction) that slows down the wheel is also given by τ_friction = Iα, where α is the angular acceleration. The initial angular velocity is (1500 rpm)(2π/60) rad/s, the final angular velocity is 0 (since the wheel comes to rest), and the time taken is 62.0 s. Using the formula α = (ω - ω₀)/t, we can calculate the angular acceleration. Substituting the values into τ_friction = Iα, we can find the frictional torque.
The applied torque is the difference between the torque needed for acceleration and the frictional torque: τ_applied = τ - τ_friction.
By performing the calculations, taking into account the given values and equations, we can determine the applied torque needed to accelerate the wheel and the effect of the frictional torque.

What is the net force acting on a 53kg object that has a velocity of 14m/s and is moving in a circle of radius 1.7m? *
Answers
The net force acting on the 53 kg object moving in a circle with a radius of 1.7 m and a velocity of 14 m/s is approximately 6109.37 N directed towards the center of the circle.
The net force acting on an object moving in a circle is called centripetal force. It is directed towards the center of the circle and is responsible for keeping the object in circular motion. To calculate the centripetal force, we use the formula:
F_c = m * a_c,
where F_c is the centripetal force, m is the mass of the object, and a_c is the centripetal acceleration. The centripetal acceleration can be calculated using the formula:
a_c = v^2 / r,
where v is the velocity of the object, and r is the radius of the circle.
Given the mass (m) of the object as 53 kg, the velocity (v) as 14 m/s, and the radius (r) of the circle as 1.7 m, we can calculate the centripetal acceleration:
a_c = (14 m/s)^2 / 1.7 m = 196 m^2/s^2 / 1.7 m = 115.29 m/s^2.
Now we can find the centripetal force:
F_c = 53 kg * 115.29 m/s^2 = 6109.37 N.

Answers
The entry to record the transaction of a corporation issuing 210 shares of its $5 par value common stock in payment of a $2,900 charge from its accountant for assistance in filing its charter with the state would include the following:
Debit: Organization Costs Expense (or Professional Fees Expense) - $2,900
Credit: Common Stock (Par Value) - $5 x 210 shares - $1,050
Credit: Additional Paid-in Capital (or Paid-in Capital in Excess of Par Value) - $2,900 - $1,050 = $1,850
Explanation:
The debit to Organization Costs Expense (or Professional Fees Expense) records the expense incurred for the accountant's assistance in filing the charter.
The credit to Common Stock accounts for the par value of the shares issued. In this case, it would be $5 multiplied by the 210 shares.
The credit to Additional Paid-in Capital (or Paid-in Capital in Excess of Par Value) accounts for the difference between the total payment made ($2,900) and the par value of the shares issued ($1,050). This represents the amount contributed by shareholders above the par value.

what does one prolonged blast emitted by boat a using an efficient sound producing device indicate?3
Answers
A prolonged blast emitted by Boat A using an efficient sound-producing device is typically used as a sound signal to indicate a specific message or action.
The meaning of a prolonged blast depends on the context and is often governed by marine regulations and conventions. Here are three common interpretations of a prolonged blast signal:
Warning Signal: In many jurisdictions, a prolonged blast is used as a warning signal to indicate potential danger or the presence of a vessel in a restricted visibility situation. For example, if Boat A is navigating in foggy conditions or during reduced visibility, it may emit a prolonged blast to warn nearby vessels of its presence and indicate that it is maneuvering cautiously.
Request for Passage: In certain circumstances, a prolonged blast can serve as a request for passage. For instance, if Boat A intends to overtake or pass another vessel, it may emit a prolonged blast to signal its intention and request the other vessel's cooperation in granting safe passage.
Signal for Restricted Maneuverability: Another use of a prolonged blast is to indicate that Boat A has limited maneuverability due to its size, shape, or operational conditions. This signal is often employed by large vessels, such as ships or barges, to alert other vessels to exercise caution when navigating in their vicinity.
It is important to note that the interpretation of sound signals may vary depending on the specific rules and regulations of the maritime jurisdiction in which Boat A is operating. Vessel operators must be familiar with the applicable regulations and conventions to correctly interpret and respond to different sound signals.
To ensure safe and efficient communication among vessels, the International Regulations for Preventing Collisions at Sea (COLREGs) provide standardized guidelines for the use of sound signals. These regulations establish rules for various sound signals, including prolonged blasts, short blasts, and combinations of blasts, to facilitate clear communication and prevent collisions at sea.
In summary, a prolonged blast emitted by Boat A using an efficient sound-producing device can indicate a warning signal, a request for passage, or signal restricted maneuverability. The specific meaning of the signal depends on the context and applicable maritime regulations and conventions.

with the switch open, what is the potential difference between the plates which are separated by a distance d
Answers
If the switch is open, there will be no potential difference between the plates since no current is flowing through the circuit to establish a potential difference.
A potential difference, or voltage, is the electrical energy per unit charge that is transferred between two points in a circuit. In this case, the plates are separated by a distance d and are part of a circuit that includes a switch. When the switch is open, the circuit is not complete and no current flows through it. Therefore, there is no transfer of electrical energy between the plates, and no potential difference exists between them.
When a switch is open, it acts as a gap in the circuit, interrupting the flow of electrical current. This means that there is no electrical energy being transferred from one plate to the other.
Potential difference, also known as voltage, is the measure of the electric potential energy per unit charge between two points in a circuit. It is calculated as the work done per unit charge to move a small test charge from one point to another in an electric field.

of the following factors, ________ drives tfr down.
Answers
Of the following factors, Economic development drives the Total Fertility Rate (TFR) down.
Hence, the correct option is a.
Total Fertility Rate is a measure that represents the average number of children born to a woman over her reproductive lifetime in a given population. Various factors influence the TFR, including social, cultural, and economic factors. However, economic development has been consistently identified as a key factor associated with declining fertility rates.
As countries experience economic development, several changes occur that tend to lower fertility rates. These include:
1. Increased access to education: Economic development often leads to improved educational opportunities, especially for women. When women have access to education, they are more likely to pursue careers and delay or limit childbearing, leading to lower fertility rates.
2. Urbanization and industrialization: Economic development is often accompanied by urbanization and industrialization. As people move from rural to urban areas and engage in industrial and service sectors, there is a shift in lifestyle and economic demands. Urban environments usually offer better access to healthcare, family planning services, and employment opportunities, which can lead to lower fertility rates.
3. Improved healthcare and family planning: Economic development often leads to advancements in healthcare systems, including access to reproductive health services and family planning.
4. Changing social norms and aspirations: Economic development can bring about changes in societal values and aspirations. As individuals and families achieve higher living standards and economic security, there may be a shift in preferences towards smaller family sizes. Economic opportunities and financial considerations play a role in decision-making regarding childbearing, leading to lower fertility rates.
Overall, economic development influences various socio-economic factors that affect fertility rates. As countries progress economically, fertility tends to decline due to factors such as increased education, urbanization, improved healthcare, and changing societal norms and aspirations.

FITT principle:
Frequency-is how regular or often a person does the plan of a target health-related physical activity. It depends on how determined you want to accomplish your target. The more often you train, the faster the result.
Intensity - is how hard a person exercise during a physical activity period. It can be measured in different ways, depending on the health-related component. For example, monitoring heart rate is one way to measure the intensity during aerobic endurance activities, but does not indicate intensity during flexibility activities. The harder you work, the faster your heart beats.
Time - is the duration of the physical activity. Together with the other aspects of the FITT principle, time varies depending on the target health-related fitness component. For example, in developing flexibility, stretching may take 10-30 seconds for each activity, while the minimum time for performing an aerobic exercise is 20 minutes of continuous action.
Type - refers to the physical activity chosen to improve a specific component of health-related fitness. Different events require different training programs. For example, if a person wants to increase core muscles, he or she must do exercises that target the oblique muscles, while another person wishing to improve his or her cardiovascular endurance needs to jog, run, swim or perform some other aerobic activities.

if the universe is 13.8 billion years old, how can we see 46 billion light years away
Answers
if the universe is 13.8 billion years old, how can we see 46 billion light years away because space has also been expanding?
When total distance to distant cosmic objects like galaxies is taken into account, their measurement is referred to as cosmological distance. This distance accounts for universe's ongoing expansion. Space itself stretches as a result of the universe's expansion, causing two things' distances to grow even when they are not physically moving apart.
One may observe objects that are currently positioned farther distant than the age of the universe thanks to this stretching of space. For a very long time, light emanating from these far-off objects has been travelling through space. Light has essentially travelled a greater distance than the actual physical distance between us and the object because of the universe's expansion during that time.

12. For what value(s) of \( x \) is the instantaneous rate of change in \( f(x)=2^{x} \) positive? Explain.
Answers
The instantaneous rate of change of \(f(x) = 2^x\) is positive for all values of x.
The instantaneous rate of change of a function f(x) at a specific point is given by the derivative of the function evaluated at that point. In this case, we have \(f(x) = 2^x\), and we want to find the values of x for which the instantaneous rate of change is positive.
To find the derivative of \(f(x) = 2^x\), we can use the power rule for differentiation. The derivative of \(a^x\) with respect to x is \(a^x * ln(a)\), where a is a constant. Applying this rule to our function, we have f'(x) = 2^x * ln(2).
Now, we want to find the values of x for which \(f'(x)\) is positive. Since \(ln(2)\) is a positive constant, the sign of \(f'(x)\)is determined solely by the term 2^x. Recall that \(2^x\) is positive for any real value of x.
Therefore, the instantaneous rate of change of \(f(x) = 2^x\) is positive for all values of x.

A flat car of mass $m_0$ starts moving to the right due to a constant horizontal force $F$. Sand spills on the flat car from a stationary hopper. The velocity of the loading is constant and is equal to $\mu$, with units $\mathrm{kg/s}$. What is the velocity of the car in the process of loading as a function of time
Answers
The velocity of the car in the process of loading can be described as a linear function of time, increasing steadily over time due to the constant horizontal force applied.
As the car starts moving to the right due to the constant horizontal force applied, sand spills onto the car from a stationary hopper. The velocity of the loading process remains constant and is denoted as $\mu$, with units of kg/s.
Since the velocity of the car is directly related to the amount of sand loaded onto it, and the rate of loading is constant, we can express the velocity of the car as a linear function of time. The velocity will increase linearly with time as more sand is loaded onto the car.
Mathematically, we can express the velocity of the car as:
$v(t) = \mu t$
Where $v(t)$ represents the velocity of the car at time $t$. As time progresses, the velocity of the car increases linearly at a rate of $\mu$ kg/s.
It's important to note that this linear relationship assumes that there are no external factors affecting the motion of the car, such as friction or additional forces. In a real-world scenario, these factors may need to be considered for a more accurate analysis.

Translation-Adding more gas to a tank, the internal pressure will increase because by increasing the number of particles?
Adding more gas to a tank, the internal pressure will increase because by increasing the number of particles increases collision between particles.
The frequency of collisions between gas particles and the container walls determines the gas pressure. The number of collisions and consequently the pressure will rise if we fill the container with more gas particles.
The Avogadro Principle (V N) states the frequency of collisions with the container walls must increase as the number of gas particles increases. The pressure of the gas then rises as a result of this. Pressure rises as the number of gas molecules rises while the volume of the container stays the same. Gas pressure rises as container volume decreases. The pressure rises as the temperature of a gas inside a rigid container rises.

de densidad en lugar de mercurio, ¿cuál sería la altura que alcanzaría la columna de
aceite?
Answers
Answer:
La columna de aceite tendría una altura de 11,613 metros.
Explanation:
El modelo de Torricelli basa el cálculo de la presión atmosférica mediante el concepto de presión hidrostática, en donde la densidad del fluido (\(\rho\)), en kilogramos por metro cúbico, es inversamente proporcional a la altura de la columna (\(h\)), en metros, para una igual presión atmosférica (\(P\)), en atmósferas. Entonces, podemos estimar la altura de la columna mediante el siguiente modelo:
\(\rho_{Hg}\cdot h_{Hg} = \rho_{o}\cdot h_{o}\) (1)
Donde:
\(\rho_{Hg}\) - Densidad del mercurio.
\(h_{Hg}\) - Altura de la columna de mercurio.
\(\rho_{o}\) - Densidad del aceite.
\(h_{o}\) - Altura de la columna del aceite.
Si sabemos que \(\rho_{Hg} = 13600\,\frac{kg}{m^{3}}\), \(h_{Hg} = 0,760\,m\) y \(\rho_{o} = 890\,\frac{kg}{m^{3}}\), entonces la altura de la columna del aceite es:
\(h_{o} = \left(\frac{\rho_{Hg}}{rho_{o}} \right)\cdot h_{Hg}\)
\(h_{o} = \frac{13600\,\frac{kg}{m^{3}} }{890\,\frac{kg}{m^{3}} }\times (0,760\,m)\)
\(h_{o} = 11,613\,m\)
La columna de aceite tendría una altura de 11,613 metros.

Answers
A uniform beam can be in rotational equilibrium but not translational equilibrium if there is a force acting on the beam that causes a torque but does not cause any net force in any particular direction
Explanation - A uniform beam is rotational equilibrium but not translational equilibrium because in rotational equilibrium, the net torque acting on the object is equal to zero while in translational equilibrium, the net force acting on the object is equal to zero. Here, the following are the given information: Uniform beam It is rotational equilibrium It is not translational equilibriumWhen a uniform beam is placed on two supports, it is in rotational equilibrium because the forces acting on it are balanced. This means that the net torque acting on the beam is equal to zero. However, the beam is not in translational equilibrium because the forces acting on it are not balanced. This means that the net force acting on the beam is not equal to zero.The formula for torque is τ= rF sin θwhere τ is torque, r is the distance from the pivot point to the point where the force is applied, F is the force applied, and θ is the angle between the force and the line of action of the force.In order for the beam to be in rotational equilibrium, the sum of the torques acting on it must be equal to zero. Therefore, the torques acting on one side of the beam must be equal and opposite to the torques acting on the other side of the beam.

aquarium tank. How might you combine the
"Length × Width x Height" formula with the
displacement method to determine the
shark's volume? Explain.
Answers
The displacement method can be used to determine the shark's volume by measuring the corresponding volume of the displaced water in the can.
How to measure the volume of irregular shapeIf the object has an irregular shape , the volume can be measured using a displacement can.
The displacement can is filled with water above a narrow spout and allowed to drain until the water is level with the spout. As the irregular object is lowered into the displacement can, the water level rises.
The level of water displaced is the volume of the irregular shape.
Thus, the displacement method can be used to determine the shark's volume by measuring the corresponding volume of the displaced water in the can.

49.9 kg?
(Unit = m^3)
Answers
Answer:
0.1848
Explanation:
p=m/v
where
p=density
m=mass
v=volume
Substitute the values and solve
the answer is 0.1848
BTW, it is correct for Acellus students
The volume of a substance is its mass divided by density. The volume of Al with mass 49.9 kg and density 270 kg/m³ is 0.18 m³.
What is volume ?Volume of a substance is the space occupied by its particles. All solid and liquid substance have a definite volume. Volume is generally expressed in liters or milliliters. Other units of volume are cm³, m³ etc.
Density of a substance describes how closely its particles are packed within a given volume. Thus, it is mass per unit volume of the substance. Density depends on the pressure and temperature also.
Given that mass of Al = 49.9 kg
density = 270 kg/m³
then, volume = mass/density
v = 49.9 kg / 270 kg/m³ = 0.18 m³.
Therefore, the volume of Al for the given mass is 0.18 m³.
