Answer:

Explanation:
given,
In first case Volume remains constant.
Work done in the first case is zero.
In Second case Volume change
V₁ = 0.2 m³
V₂ = 0.11 m³
Pressure, P = 5.5 x 10⁵ Pa
Work done = Pressure x change in volume
W = P ΔV



Hence, Work done when volume changes is equal to 
Answer:
The signal will move down by 1 division
Explanation:
We have two signals here:
- An AC signal (sine wave), centered at 0 V, with amplitude 2 V (it means that it goes from a maximum of +2 V to a minimum of -2 V)
- A DC signal, which appears in the oscilloscope as a flat line, of 1 V
If we add these two signals together, we are adding a constant offset of +1 V to the sine wave, so the sine wave will move up by one division
Now, if we readjust the position so the trace is centered again at 0 V, we are moving the signal down by 1 division
Then, if we switch the signal in channel B from DC to AC, we are removing the constant offset of 1 V - so the signal will be now centered at -1 V. Therefore, the signal will move down by 1 division.
Density is mass divided by volume, you would have to solve for the volume of the ball and rearrange the equation to density divided by volume equals mass
The distance between the two masses is d = 1.35 m
The force between the masses is

Let the mass of object 1 be m.
Let the mass of object 2 be 2m.
The formula of force can be written as

Here, the universal gravitational constant is

The mass can be calculated as

The mass of object 2 is

The mass of the first object is 8.45 kg.
The mass of the second object is 16.9 kg.
Answer:
Temperature:-it is the measure of kinetic energy of of matter .
- It determines the direction of heat energy .
- SI unit of temperature is kelvin.
- Temperature is measured by thermometer.
Heat is related to total kinetic energy whereas temperature is related to average kinetic energy.
