A. Which of the four thermal processes describes the pressure-volume relationship at a constant temperature?

Answer:

Boyle's law, which describes the relationship between the pressure and the volume of a gas when the temperature remains constant.

Explanation:

Boyle's law says that the pressure of a gas in a closed container is inversely proportional to the volume of the container that contains it, when the temperature is constant. This means that if the pressure increases, the volume decreases, and if the pressure decreases, the volume increases.

The formula that describes this law is as follows:

P1 * V1 = P2 * V2

Where P1 is the gas pressure in the initial state, V1 is the volume of the gas in the initial state and P2 and V2 is the pressure and volume in the final state.

The inside of a race car often looks very different from the inside of a normal car. Race car teams often remove seats and other
Digiron [165]

Explanation:

A race car's main target is how to have rapid acceleration by scaling its speed. Acceleration of car is mostly a product of the force of the car engine.

According the newtons second law"The acceleration of body in motion depends on two main variables, the net force acting on it and the mass".

   It is also written mathematically as:

    F = m x a

F is the net force produced by the engine

m is the mass of the car

a is the acceleration.

Re-writing the equation:

 Now   Acceleration = \frac{Force }{mass}

We can see that acceleration is directly related to increasing force but inversely proportional to the mass.

A race car needs to have a good acceleration so as to attain top speed.

  The more the mass, the less the acceleration.

This is why extra weight like the seats are expunged.

A duck floating on a lake oscillates up and down
slega [8]
<span>The answer is (2) 0.50 Hz. The frequency (f) of oscillation is the number of oscillations (n) per time (t) in seconds: f = n/t. A duck floating on a lake oscillates up and down 5.0 times (n = 5.0) during a 10.-second interval (t = 10.0 s). So, the frequency of duck's oscillations is: f = 5.0/10.0 s = 0.50 1/s = 0.50 Hz.Hope I helped! :) Cheers!</span>

goldenfox [79]

According to Newton's 3rd law, there will be equal and opposite force on the astronaut which is  -6048 N

<h3>What does Newton's third law say ?</h3>

The law state that in every action, there will be equal and opposite reaction.

Given that a rocket takes off from Earth's surface, accelerating straight up at 69.2 m/s2. We are to calculate the normal force (in N) acting on an astronaut of mass 87.4 kg, including his space suit.

Let us first calculate the force involved in the acceleration of the rocket by using the formula

F = ma

Where mass m = 87.4 kg, acceleration a = 69.2 m/s2

Substitute the two parameters into the formula

F = 87.4 x 69.2

F = 6048.08 N

According to the Newton's 3rd law, there will be equal and opposite force on the astronaut.

Therefore, the normal force acting on the astronaut is -6048 N approximately

Write about the similarities and differences between kinetic and potential energy. Include specific, real world example in your
lord [1]

Answer:

Energy is transformed from potential to kinetic and vice versa

Explanation:

The energy is transformed from mechanical to kinetic energy when the object changes its position with respect to a reference point, where it loses height but increases its speed. When the object is at maximum height with respect to a reference point, it will have its maximum potential energy value. When the object passes through the reference point it will have potential energy equal to zero, but this energy will become kinetic energy.

The most characteristic and real example is that of a pendulum at one end, as can be seen in the attached image.

When the pendulum is located at the top end, as shown in Figure 1, at that point the maximum potential energy will be held. Then the pendulum is released and when it passes through the reference point and its height is zero, with respect to that point, all potential energy will have become kinetic energy in the same way at this point the maximum speed of the pendulum will be set.
