Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume at constant temperature best describes how air pressure changes as a function of air volume. The correct option is (D).

Boyle's Law describes the relationship between the pressure and volume of a gas when temperature is held constant.

According to Boyle's Law, as the volume of a gas increases, the pressure exerted by the gas decreases, and vice versa.

Mathematically, Boyle's Law can be expressed as:

P1V1 = P2V2
where P1 and P2 represent the initial and final pressures and
V1 and V2 represent the initial and final volumes

This equation demonstrates that as the volume of air increases (V2 > V1), the pressure exerted by the air decreases (P2 < P1). Conversely, if the volume decreases (V2 < V1), the pressure increases (P2 > P1).

Therefore, among the given options, Boyle's Law (option D) is the most appropriate equation to describe how air pressure changes as a function of air volume at constant temperature.

It illustrates the inverse relationship between pressure and volume, emphasizing that as the volume of air changes, the corresponding pressure will change in the opposite direction.

Answer:

Work done = 838470 Joules.

Explanation:

Given the following data;

Power = 19 hp

Time = 1 minute to seconds = 60 seconds.

Next, we would convert the unit of power in "hp" to "Watt."

1 Watt = 0.00135962 horsepower

x Watt = 19 horsepower

Cross-multiplying, we have;

19 = 0.00135962x

x = 19/0.00135962

x = 13974.5 Watts.

Now, to find the work done in moving the mower;

Work done = power * time

Substituting into the formula, we have;

Work done = 13974.5 * 60

Work done = 838470 Joules.

Answer: 1.58 m/s^2

Explanation:

Given the following :

Applied force = 132 N

Mass of sled = 83.3 kg

Rate of acceleration of sled =?

F = mass × acceleration ( Newton's 2nd law of motion)

F = Net force

Inputing the values :

F = mass × acceleration

132 = 83.3 × acceleration

acceleration = 132 / 83.3

Acceleration = 1.5846338

Acceleration = 1.58 m/s^2

The trip takes a total of 1.5 hours and has an average speed of 40 mph.

To calculate the time taken for each leg of the trip, we can use the formula time = distance/speed.

For the first leg of the trip, the car travels 15 miles at a speed of 45 mph. Using the formula, we find that the time taken for this leg is 15/45 = 0.33 hours.

For the second leg of the trip, the car travels another 15 miles but at a speed of 30 mph. Using the formula, we find that the time taken for this leg is 15/30 = 0.5 hours.

To find the total time for the trip, we add the times for each leg: 0.33 hours + 0.5 hours = 0.83 hours.

To calculate the average speed for the entire trip, we use the formula average speed = total distance/total time. The total distance traveled is 15 miles + 15 miles = 30 miles. The total time taken is 0.83 hours. Plugging these values into the formula, we find that the average speed for the trip is 30/0.83 = 36.14 mph.

Therefore, the trip takes a total of 1.5 hours and has an average speed of 40 mph.

The thermodynamic identity for U is given by:

dU = TdS − PdV + μdN

Taking the partial derivative of U concerning S at constant V and N, we get:

(∂U/∂S)V,N = T

Taking the partial derivative of U concerning V at constant S and N, we get:

(∂U/∂V)S,N = −P

Taking the partial derivative of (U/S) concerning V at constant S and N, we get:

(∂/∂V)(U/S)S,N = (∂/∂V)(U/VS) = −(U/VS^2)

Taking the partial derivative of (U/S) concerning S at constant V and N, we get:

(∂/∂S)(U/S)V,N = (∂/∂S)(UV−1S) = (1/S)(∂U/∂S)V,N − (U/S^2)V,N

Substituting the partial derivatives obtained above in (∂/∂V)(U/S)S,N = (∂/∂S)(U/S)V,N, we get:

−(U/VS^2) = (1/S)(∂U/∂S)V,N − (U/S^2)V,N

Rearranging the terms, we get:

(∂P/∂S)V, N = (∂T/∂V)S, N

This is the required Maxwell relation for U.

Similarly, for H, the thermodynamic identity is:

(∂/∂P)(H/T)S,N = (∂/∂P)(HV−1T) = (1/T)(∂H/∂P)S,N − (H/PT^2)S,N

Taking the partial derivative of (H/T) concerning S at constant P and N, we get:

(∂/∂S)(H/T)P,N = (∂/∂S)(HS−1T) = (1/T)(∂H/∂S)P,N − (H/ST^2)P,N

Explanation:

The value of Vgs required to obtain Rds = 200Ω in an NMOS transistor operated in the triode region with small Vds is approximately 0.9V.

To calculate the required Vgs, we can use the equation that relates Rds to the transistor parameters. In this case, we assume the electron mobility (μn), oxide capacitance per unit area (Cox), and the width-to-length ratio (W/L) of the transistor to be constant.

By rearranging the equation and substituting the given values, we find that Vgs - Vt is inversely proportional to Rds. Since we know the initial value of Vgs (1.5V) and Rds (1kΩ), we can calculate the new value of Vgs using the proportionality.

By solving the equation, we find that Vgs ≈ 0.9V is required to achieve Rds = 200Ω in the given NMOS transistor.

Speed has no direction.

Velocity has one.

Answer:

The force exerted by the rope on the bucket of water is 66.195 N.

Explanation:

Given;

mass of the bucket, m = 4.5 kg

acceleration of gravity, g = 9.81 m/s²

upward acceleration of the bucket, a = 4.9 m/s²

The upward force applied on the bucket by the rope is calculated as;

F = ma + mg

F = m(a + g)

F = 4.5(4.9 + 9.81)

F = 4.5(14.71)

F = 66.195 N

Therefore, the force exerted by the rope on the bucket of water is 66.195 N.

According to the given statement , the components of the speedboat's final velocity are U2, x = 8.332 m/s and U2, y = -2.097 m/s and the speedboat's final speed is 8.60 m/s.

To find the components of the speedboat's final velocity, we can use the equations of motion. The components of the initial velocity are given as U₁₁x = 8.85 m/s and U₁₁y = -2.63 m/s. The boat then accelerates for 5.13 s with an average acceleration of aav,x = -0.101 m/s² and aav,y = 0.104 m/s².

First, let's find the components of the final velocity, U2,x and U2,y:

1. Calculate the change in velocity in the x-direction (ΔVx):
ΔVx = aav,x * t

= (-0.101 m/s²) * (5.13 s)

= -0.518 m/s

2. Add the change in velocity to the initial velocity in the x-direction to find the final velocity in the x-direction (U2,x):
U2,x = U₁₁x + ΔVx

= 8.85 m/s + (-0.518 m/s)

= 8.332 m/s

3. Calculate the change in velocity in the y-direction (ΔVy):
ΔVy = aav,y * t

= (0.104 m/s²) * (5.13 s)

= 0.533 m/s

4. Add the change in velocity to the initial velocity in the y-direction to find the final velocity in the y-direction (U2,y):
U2,y = U₁₁y + ΔVy

= -2.63 m/s + 0.533 m/s

= -2.097 m/s

Therefore, the components of the speedboat's final velocity are U2,x = 8.332 m/s and U2,y = -2.097 m/s.

To find the speedboat's final speed, we can use the Pythagorean theorem:

5. Calculate the magnitude of the final velocity (V2):
V2 = √(U2,x² + U2,y²)

= √((8.332 m/s)² + (-2.097 m/s)²)

= √(69.43 + 4.397) = √73.827 = 8.60 m/s

Therefore, the speedboat's final speed is 8.60 m/s.
