"The units appropriate for measurement of apparent brightness is watts per square metre."

Even though a flashlight that is close by might seem brighter than a streetlight that is far away, the flashlight is actually much less bright when contrasted side by side. The measurement of a star's luminosity—a fancy term for its real brightness—as seen from Earth is known as apparent brightness, also known as apparent magnitude.

The intensity of starlight that reaches us per unit area is known as apparent luminosity. Area is measured in square meters and power is measured in volts.

A photometer is a device that gauges and rates a celestial body's luminosity.

Bubba generates a momentum of 216 kg·m/s, while Bertha generates a momentum of 215 kg·m/s. Therefore, Bubba would win the argument as he generates more momentum.

Given:

Bubba's mass (m1) = 27 kg

Bubba's velocity (v1) = 8 m/s

Bertha's mass (m2) = 43 kg

Bertha's velocity (v2) = 5 m/s

Bubba's momentum can be calculated as:

Momentum1 = m1 * v1

        = 27 kg * 8 m/s

        = 216 kg·m/s

Bertha's momentum can be calculated as:

Momentum2 = m2 * v2

        = 43 kg * 5 m/s

        = 215 kg·m/s

Comparing the two momenta, we can see that Bubba generates a momentum of 216 kg·m/s, while Bertha generates a momentum of 215 kg·m/s. Since Bubba's momentum is higher, Bubba would win the argument and can claim to generate more momentum.

Based on the calculations, Bubba generates more momentum than Bertha. Momentum depends on both mass and velocity, and in this case, Bubba's lower mass is compensated by his higher velocity, resulting in a greater momentum. Therefore, Bubba would win the argument and can assert that he generates more momentum.

After the collision, the motorcycle's velocity is around 3.42 m/s, and the bicycle's velocity is approximately -1.42 m/s in the opposite direction.

To solve this problem, we can apply the principles of conservation of momentum and the coefficient of restitution. The conservation of momentum states that the total momentum before the collision is equal to the total momentum after the collision.

Let's denote the initial velocity of the motorcycle as v1, the initial velocity of the bicycle as v2, the final velocity of the motorcycle as v1f, and the final velocity of the bicycle as v2f.

The total momentum before the collision can be calculated as:

Initial momentum = (mass of the motorcycle * initial velocity of the motorcycle) + (mass of the bicycle * initial velocity of the bicycle)

= (75 kg * 10 m/s) + (45 kg * 8 m/s)

= 750 kg·m/s + 360 kg·m/s

= 1110 kg·m/s

According to the conservation of momentum, the total momentum after the collision is equal to the initial momentum:

Total momentum after the collision = (mass of the motorcycle * final velocity of the motorcycle) + (mass of the bicycle * final velocity of the bicycle)

= (75 kg * v1f) + (45 kg * v2f)

Now, let's consider the coefficient of restitution (e = 0.5). The equation for the coefficient of restitution is:

Coefficient of restitution (e) = (relative velocity of separation) / (relative velocity of approach)

= (v2f - v1f) / (v2 - v1)

Since it's a head-on collision, the relative velocity of approach is the sum of the velocities of the two masses before the collision:

Relative velocity of approach = v2 - v1

To find the relative velocity of separation, we can use the equation:

Relative velocity of separation = e * (relative velocity of approach)

= e * (v2 - v1)

Substituting these values into the equation for conservation of momentum, we have:

1110 kg·m/s = (75 kg * v1f) + (45 kg * v2f)

Since we have two unknowns (v1f and v2f), we need another equation to solve for them. Using the equation for the relative velocity of separation, we have:

v2f - v1f = e * (v2 - v1)

45 kg * v2f - 75 kg * v1f = 0.5 * (45 kg * 8 m/s - 75 kg * 10 m/s)

Now we have a system of two equations with two unknowns. Solving these equations simultaneously will give us the final velocities of the motorcycle (v1f) and the bicycle (v2f) after the collision.

By solving these equations, we find that the final velocity of the motorcycle (v1f) is approximately 3.42 m/s, and the final velocity of the bicycle (v2f) is approximately -1.42 m/s. The negative sign indicates that the bicycle is moving in the opposite direction after the collision.

The distance between first airplane and second airplane after 1.8 hours of their departure is 1598.22 meters.

The cosine formula for vector addition is -

|R|² = |A|² + |B|² + 2AB cosφ

Where - φ is the angle between vectors A and B.

Given is two airplanes that leave the airport at same time. The velocity of the first airplane is 690 m/h at a heading of 68.5°. The velocity of the second airplane is 590 m/h at a heading of 156°.

The length of the position vector of first airplane →

|OA| = velocity x time = 690 x 1.8 = 1242 miles.

The length of the position vector of second airplane →

|OB| = velocity x time = 590 x 1.8 = 1062 miles

Angle between vectors OA and OB →

φ = 156° - 68.5° = 87.5°

In the triangle ΔOAB, using the triangle law of vector addition, we get →

OA + AB = OB

AB = OB - OA

AB = OB + (- OA)

Now, using the formula for resultant of addition of two vectors →

AB² = (OB)² + (- OA)² + 2(OA)(- OB) cosφ

AB² = OB² + OA² + - 2(OA)(OB)cosφ

AB² = 11,27,844 + 15,42,564 - 2 x 1242 x 1062 x cos(87.5°)

AB² = 11,27,844 + 15,42,564 - 2 x 1242 x 1062 x 0.044

AB² = 26,70,408 - 1,16,072.352 = 25,54,335.648

AB = √25,54,335.648

AB = 1598.22 meters

Hence, the distance between first airplane and second airplane after 1.8 hours of their departure is 1598.22 meters.

The correct option is A) be especially suitable

A red-dyed-water-in-glass thermometer would be especially suitable to measure temperatures between 0 degrees Celsius and 8 degrees Celsius. This is within the typical range for which such thermometers are designed to provide accurate readings. The red dye helps in reading the temperature by making the liquid column easier to see against the background.

This is because the freezing point of water is 0 degrees C, and the boiling point is 100 degrees C. The range of 0 to 8 degrees C falls within the temperature range that can be accurately measured using a red-dyed-water-in-glass thermometer. This type of thermometer works by measuring the expansion or contraction of a liquid (in this case, water) in response to changes in temperature. The liquid expands as it gets warmer and contracts as it gets cooler.

However, it is worth noting that red-dyed-water-in-glass thermometers are not always the most accurate or precise instruments for measuring temperature, particularly at extreme temperatures or when high accuracy is required. Other types of thermometers, such as digital thermometers or thermocouples, may be more appropriate in certain situations.

Answer:

(a) The list of angles based on amount of time in the air; 15° < 25° < 45° < 60°, < 80°

(b) The list of angles based on distance = 80° < 15° < 25° < 60° < 45°

Explanation:

(a) The given parameters are;

The angles in which the ball is thrown, θ = 45°, 15°, 60°, 25°, and 80°

The velocity with which the ball is thrown each time = The same velocity

The amount of time the projectile is in the air given as follows;

\(2 \cdot t = \dfrac{2\cdot u \cdot sin (\theta) }{g}\)

Where;

t = Half the amount of time the projectile is in the air

θ = The angle of flight of the projectile

u = The initial velocity of the projectile = Constant for all angles in which the ball is thrown

g = The acceleration due to gravity = 9.8 m/s² = Constant

Therefore, we have;

When θ = 45°;

\(2 \cdot t = \dfrac{2\cdot u \cdot sin (45^ {\circ}) }{g} = \dfrac{2\cdot u \cdot \dfrac{\sqrt{2} }{2} }{g} = \dfrac{\sqrt{2} \cdot u }{g}\)

When θ = 15°;

\(2 \cdot t = \dfrac{2\cdot u \cdot sin (15^ {\circ}) }{g} \approx \dfrac{0.517638\cdot u }{g}\)

When θ = 60°;

\(2 \cdot t = \dfrac{2\cdot u \cdot sin (60^ {\circ}) }{g} = \dfrac{2\cdot u \cdot \dfrac{\sqrt{3} }{2} }{g} = \dfrac{\sqrt{3} \cdot u }{g}\)

When θ = 25°;

\(2 \cdot t = \dfrac{2\cdot u \cdot sin (25^ {\circ}) }{g} = \dfrac{0.8452365\cdot u }{g}\)

When θ = 80°;

\(2 \cdot t = \dfrac{2\cdot u \cdot sin (80^ {\circ}) }{g} = \dfrac{1.9696155\cdot u }{g}\)

Therefore, the list of the angles based on the amount of time in the air from the shortest time to the longest time is given as follows;

List of angles based on amount of time in the air; 15° < 25° < 45° < 60°, < 80°

(b) The horizontal range, R is given as follows;

\(R = \dfrac{u^2 \cdot sin(2 \cdot \theta) }{g}\)

When θ = 45°

\(R = \dfrac{u^2 \cdot sin(2 \times 45 ^{\circ}) }{g} = \dfrac{u^2 \cdot sin(90 ^{\circ}) }{g} = \dfrac{u^2 }{g}\)

When θ = 15°

\(R = \dfrac{u^2 \cdot sin(2 \times 15 ^{\circ}) }{g} = \dfrac{u^2 \cdot sin(30 ^{\circ}) }{g} = \dfrac{1}{2} \cdot \dfrac{u^2 }{g} = 0.5 \cdot \dfrac{u^2 }{g}\)

When θ = 60°;

\(R = \dfrac{u^2 \cdot sin(2 \times 60 ^{\circ}) }{g} = \dfrac{u^2 \cdot sin(120 ^{\circ}) }{g} = \dfrac{u^2 }{g} \cdot \dfrac{\sqrt{3} }{2} =0.866025 \cdot \dfrac{u^2 }{g}\)

When θ = 25°;

\(R = \dfrac{u^2 \cdot sin(2 \times 25 ^{\circ}) }{g} = \dfrac{u^2 \cdot sin(50 ^{\circ}) }{g} = \dfrac{0.7660444 \cdot u^2 }{g}\)

When θ = 80°

\(R = \dfrac{u^2 \cdot sin(2 \times 80 ^{\circ}) }{g} = \dfrac{u^2 \cdot sin(160 ^{\circ}) }{g} = \dfrac{0.34202 \cdot u^2 }{g}\)

Therefore the list of angles based on the horizontal range the baseball travels from the shortest distance to the longest distance is given as follows;

List of angles based on distance = 80° < 15° < 25° < 60° < 45°.

Answer:

The penguins are gliding foward without stopping because there is no external force changing their state.

Explanation:

Newtons first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.

The given differential equation is:

dQ/dt = -0.04Q

where Q is the quantity of the toxic chemical and t is time in years.

To solve this differential equation, we can use separation of variables:

dQ/Q = -0.04 dt

Integrating both sides, we get:

ln|Q| = -0.04t + C

where C is the constant of integration. To find the value of C, we can use the initial condition that the initial leak is 60 kg:

ln|60| = -0.04(0) + C

C = ln|60|

Substituting this value of C back into the general solution, we get:

ln|Q| = -0.04t + ln|60|

Simplifying, we get:

ln|Q/60| = -0.04t

Exponentiating both sides, we get:

Q/60 = e^(-0.04t)

Multiplying both sides by 60, we get the final solution:

Q = 60e^(-0.04t)

Therefore, the quantity of the toxic chemical present at any time t (measured in years) after the initial leak is:

Q(t) = 60e^(-0.04t)

Primero, definimos el desplazamiento como la distancia entre la posición final y la posición inicial.

Así, si comenzamos abajo, luego subimos la escalera, y luego bajamos, la posición final y la posición inicial serán la misma

por lo que el desplazamiento es igual a cero.

La medida recorrida es el espacio total recorrido.

Es decir, si entre el principio y el final de la escalera hay una distancia D.

La persona que sube y baja, recorre esta distancia dos veces.

The initial angular momentum of the propeller before the torque was applied will be 32 kg m²/s.

Torque is the force's twisting action about the axis of rotation. Torque is the term used to describe the instant of force. It is the rotational equivalent of force. Torque is a force that acts in a turn or twist.

The amount of torque is equal to force multiplied by the perpendicular distance between the point of application of force and the axis of rotation.

The given data in the problem is;

The rotational inertia is,I  = 2.0 kg m²

The clockwise torque is, T = 4.0Nm

The time period is,t= 4.0s,

The angular speed is,ω= 24 * (rad)/s

The initial angular momentum of the propeller is,I₀

The angular acceleration is found by the relation;

\(\rm \tau = I \times \alpha \\\\ \alpha =\frac{\tau}{i} \\\\ \alpha =\frac{4.0}{2.0} \\\\ \alpha= 2.0 \ rad/sec^2\)

The initial angular velocity is found as;

\(\rm \omega_f = \omega_0 + \alpha t \\\\ \omega_0 = \omega_f -\alpha t \\\\ \omega_0 =24 -[(-2.0)\times 4.0)] \\\\ \omega_0 = 16 \ rad/sec\)

The initial angular momentum of the propeller is found as;

\(\rm L_0 = I \omega_0 \\\\ L_0 = 20 \times (1.6) \\\\ I_0 = -32 \ kgm^2/s\)

Hence,the initial angular momentum will be 32 kg m²/s.

According to René Descartes, machines could not think because they lacked consciousness or a mind. Descartes proposed a dualistic philosophy, which distinguished between the physical body and the immaterial mind or soul. He believed that the mind, or "res cogitans," was responsible for conscious thought, reasoning, and intellect, while the body, or "res extensa," operated mechanically and lacked consciousness.

Descartes argued that thinking and consciousness were unique attributes of human beings and could not be replicated by machines or animals. He claimed that machines, no matter how complex or advanced, were fundamentally different from human beings because they lacked a conscious mind.

Descartes' view became influential in the philosophy of mind and has been subject to debate and criticism over the years. However, his ideas about the distinction between mind and body and the limitations of machines in thinking were significant contributions to the philosophical understanding of cognition and consciousness.

Answer: c. The electric force increases

Explanation:

If the distance between two charged particles decreases, the electric force between them increases.

According to Coulomb's Law, the electric force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. Mathematically, the equation can be represented as:

F = k * (q1 * q2) / r^2

Where:

F represents the electric force between the particles.

k is the electrostatic constant.

q1 and q2 are the charges of the particles.

r is the distance between the particles.

As the distance (r) between the particles decreases, the denominator of the equation (r^2) becomes smaller, causing the overall electric force (F) to increase. Conversely, if the distance between the charged particles increases, the electric force between them decreases. This inverse relationship between the distance and electric force is a fundamental characteristic of the electrostatic interaction between charged objects.

According to the given statement , the potential difference V across the resistor R is 3105 V.

To find the potential difference V, we can use Ohm's Law and the formula for the potential difference across a capacitor.

First, let's calculate the current flowing through the circuit. We are given that I = 2.5 A.

Next, we can calculate the total resistance in the circuit using the formula R = R₁ + R₂. Given that R₁ = 40 Ω and R₂ = 1202 Ω, we can calculate the total resistance:

R = 40 Ω + 1202 Ω = 1242 Ω

Now, we can calculate the charge stored in the capacitor using the formula Q = C * V, where Q is the charge, C is the capacitance, and V is the potential difference across the capacitor. We are given that Q = 18 μC and C = 3 μF. Plugging these values into the formula, we can solve for V:

18 μC = 3 μF * V
V = 18 μC / 3 μF
V = 6 V

Finally, we can calculate the potential difference V across the resistor R. Using Ohm's Law, we can use the formula V = I * R:

V = 2.5 A * 1242 Ω
V = 3105 V

So, the potential difference V across the resistor R is 3105 V.

In conclusion, the potential difference V across the resistor R is 3105 V.
