Answer:

Explanation: heat of fusion

Answer:

4N to the left. No it is not balanced.

Explanation:

8 -4 = 4 N of force

Balanced would be if they equaled zero, so 8 to the left and 8 to the right

The load of 1.8 N will give it an extension of 12cm.

Amount of force required to increase unit length of a spring is known as spring constant. Si unit of spring constant is Newton/meter.

Given parameters:

Loads on the spring; F₁ = 7.5 N.

Increase in length of the spring; x₁ = 50 cm = 0.5 m.

So, spring constant of it; k = F₁/x₁ = 7.5/0.5 N/m = 15 N/m.

Hence, to extent it of 12 cm; required load

= spring constant × increase in length

= 15 N/m × 12 cm.

= 15 N/m × 0.12 m.

= 1.8 N.

So, the required load is 1.8 N.

We need to use the formula: Force = Mass × Acceleration Let's use the given values to calculate the force exerted on the deer when it is hit by the car. The car weighs 235 lb and it is traveling north at 75 mph. The deer weighs 150 lb and it is going 35 mph east. Force = 44045 lbSince the force is a vector quantity, it has both magnitude and direction.

Step 1: Convert the velocities into feet per second.1 mile = 5280 feet1 hour = 3600 seconds So, the velocity of the car is:75 mph = (75 × 5280) ÷ 3600 = 110 feet/secondThe velocity of the deer is:35 mph = (35 × 5280) ÷ 3600 = 51.3 feet/second

Step 2: Find the components of velocity of the deer. The velocity of the deer is in the east direction, so we need to find its horizontal component, vx, and its vertical component, vy. If the angle between the deer's velocity and the x-axis is θ, then: vx = v × cosθandvy = v × sinθv = 51.3 feet/secondθ = 90° - arctan(0 / 110) = 90°So,vx = 51.3 × cos90° = 0 feet/second vy = 51.3 × sin90° = 51.3 feet/second

Step 3: Find the net velocities of the car and the deer. Since the car is moving north and the deer is moving east, the net velocity of the car and deer together can be found using the Pythagorean theorem. Net velocity = √[(vx + 110)² + vy²]Net velocity = √[(0 + 110)² + (51.3)²]Net velocity = √(12100 + 2631.69)Net velocity = √14731.69Net velocity = 121.3 feet/second

Step 4: Find the net momentum of the car and the deer. Net momentum = (mass of car × velocity of car) + (mass of deer × velocity of deer)Net momentum = (235 × 110) + (150 × 121.3)Net momentum = 25850 + 18195Net momentum = 44045 lb ft/second

Step 5: Find the force exerted on the deer. Force = Net momentum ÷ time Here, time is the duration of the collision which is not given in the problem. We will assume it to be 1 second. Force = 44045 ÷ 1

Force = 44045 lb Since the force is a vector quantity, it has both magnitude and direction. The direction of force is along the line of impact which is not given in the problem.

The physical method of controlling microbial growth that applies pressure to water to create steam is called "autoclaving" or "sterilization by autoclave."

Autoclaving is a widely used method for sterilization in various industries, including healthcare, laboratories, and food processing. It involves subjecting materials or objects to high-pressure saturated steam at elevated temperatures. The combination of pressure and heat effectively kills microorganisms, including bacteria, viruses, fungi, and spores.

Autoclaves consist of a sealed chamber that can withstand high pressures, along with a source of heat and a means to generate steam. The process involves placing the items to be sterilized inside the autoclave chamber and then raising the temperature and pressure to the desired levels. The high-pressure steam penetrates the materials and destroys the microorganisms present, ensuring effective sterilization.

The typical conditions for autoclaving include temperatures ranging from 121 to 134 degrees Celsius (250 to 273 degrees Fahrenheit) and pressures between 15 and 30 pounds per square inch (psi). These conditions are maintained for a specified period, usually around 15 to 30 minutes, depending on the size and nature of the items being sterilized.

Autoclaving is advantageous because it provides a reliable and efficient method for achieving sterility. It can be used to sterilize a wide range of materials, including laboratory glassware, surgical instruments, medical equipment, media and solutions, textiles, and more. The high temperatures and pressure ensure thorough sterilization, and the process is relatively quick compared to other methods.

However, it is important to note that not all materials can be autoclaved, as some may be sensitive to heat or moisture. Additionally, certain biological substances, such as certain types of infectious waste or toxins, may require specialized treatment beyond autoclaving.

Overall, autoclaving is a highly effective method for controlling microbial growth by applying pressure to water to create steam. Its widespread use in various industries is a testament to its reliability and efficiency in achieving sterilization.

The spectral width AA of the laser is , 0.15 pm, and the separation AA of the modes in wavelength is , λ² / 200 cm.

Since, The separation between adjacent modes in a laser cavity is given by:

Δλ = λ² / (2L)

where λ is the wavelength of light, and L is the length of the cavity.

Here, In this case, L = 50 cm.

Since the laser cavity has 99% reflectance at both ends, the effective length of the cavity is twice the physical length, or L = 100 cm.

The separation between adjacent modes can be calculated as:

Δλ = λ² / (2L)

= λ² / (2 x 100 cm)

= λ² / 200 cm

The spectral width of the laser can be approximated by the linewidth of the gain medium.

For a He-Ne laser, this is typically around 1.5 GHz.

Converted to wavelength, this is approximately 0.15 pm.

For time-independent potentials, the solutions of the time-dependent Schrödinger equation can always be written as the product y(r,t) = f(r)g(t) of two functions.

In quantum mechanics, the time-dependent Schrödinger equation describes the evolution of wave functions over time. It is given by:

iħ∂ψ/∂t = -ħ²/2m∇²ψ + Vψ

where i is the imaginary unit, ħ is the reduced Planck's constant, ∂ψ/∂t represents the partial derivative of the wave function with respect to time, m is the mass of the particle, ∇²ψ is the Laplacian of the wave function, V is the potential energy, and ψ is the wave function itself.

When the potential energy V is time-independent (i.e., V = V(r)), we can separate the variables in the wave function as y(r,t) = f(r)g(t), where f(r) depends only on the spatial variables and g(t) depends only on the temporal variable.

By substituting y(r,t) into the time-dependent Schrödinger equation and performing the separation of variables, we obtain two separate equations: one involving the spatial variables and the other involving the temporal variable. The equation involving the spatial variables is the time-independent Schrödinger equation, which can be solved to find the spatial part of the wave function f(r). The equation involving the temporal variable is an ordinary differential equation that determines the time evolution of the temporal part of the wave function g(t).

Therefore, for time-independent potentials, the solutions of the time-dependent Schrödinger equation can always be written as the product y(r,t) = f(r)g(t) of two functions, where f(r) is the spatial part and g(t) is the temporal part of the wave function.

Answer:

\(\boxed {\boxed {\sf 96 \ m/s}}\)

Explanation:

We are asked to find the final velocity of the car given the acceleration and time. We can use the following kinematics equation to calculate the final velocity.

\(v_f=v_i+(a \times t)\)

The car starts from rest, so the initial velocity is 0 meters per second. It accelerates a rate of 40 meters per square second over a period of time of 2.4 seconds.

Substitute the values into the formula.

\(v_f= 0 \ m/s + ( 40 \ m/s^2 \times2.4 \ s)\)

Solve inside the parentheses.

\(v_f= 0 \ m/s + (96 \ m/s)\)

Add.

\(v_f= 96 \ m/s\)

The final velocity of the car is 96 meters per second.

The acceleration of the boxes is 1.57 m/s².

Acceleration is rate of change of velocity with time. Due to having both direction and magnitude, it is a vector quantity. Si unit of acceleration is meter/second² (m/s²).

Given parameters:

Horizontal force acting on the boxes: F = 36.0 N.

Mass of box a: M₁= 10.0 kg

Mass of box b: M₂ = 12.0 kg.

Mass of the cord: m = 1.00 kg

We have to find : the acceleration of the boxes: a = ?

Total mass of the system = M₁ + M₂ + m =  10.0 kg + 12.0 kg +1.00 kg = 23.0 kg.

So, the acceleration of the boxes:

a =  Horizontal force acting on the boxes / Total mass of the system

= 36.0 / 23.0 m/s²

= 1.57 m/s².

Hence,  the acceleration of the boxes is 1.57 m/s².

Explanation:

Q = charge in C(coulombs)

I = current in A(amps)

t = time in s(seconds)

Q = I × t

t = Q/I

Substitute in the given values.

t = 450C/15A = 30

t = 30s

Hope this helps! ^^

The heater was switched on for 30 seconds to allow 450 C of charge to flow through it.

To find the time the heater was switched on, we can use the equation Q = It,

where Q represents the total charge in coulombs, I is the current in amperes, and t is the time in seconds.

Given that the current (I) is 15 A and the total charge (Q) is 450 C, we can rearrange the equation to solve for time (t):

t = Q / I

Substitute the values:

t = 450 C / 15 A

t = 30 seconds

Therefore, the heater was switched on for 30 seconds to allow 450 C of charge to flow through it.

Explanation:

First, let's calculate the total number of watts used per day:

100 watts (while in use) + 10 watts (while idle) = 110 watts

To convert watts to kilowatts, we divide by 1000:

110 watts / 1000 = 0.11 kilowatts

So, the TV uses 0.11 kilowatts per hour.

To find the total number of kilowatts used in one year, we need to multiply the kilowatts per hour by the number of hours in a year:

0.11 kilowatts/hour * 1 hour/day * 365 days/year = 40.15 kilowatt-hours per year

Therefore, a TV watched one hour per day would use approximately 40.15 kilowatt-hours per year.

In one year, one hour of television use per day would use 36.5 kilowatts.

This is calculated by multiplying the daily wattage (100 watts while in use and 10 watts while idle) by 365 days in a year. Because most televisions are in standby mode when not in use, the 10 watts of power used while idle will be the majority of the total power used over the course of the year.

This means that even though the television is only used for one hour a day, the amount of electricity used while idle adds up over the course of a year. To reduce power consumption, it is important to keep televisions in standby mode when not in use and to unplug them when they are not going to be used for extended periods of time.
