Answer:
the force is very strong between
Answer:
Correct
Explanation:
The logs and the slope helped the men to lift the nearby stone.
The radius of the track in the circular motion is 0.164 mm.
<h3>Magnetic force of the of charge</h3>
The magnetic force of the charge is calculated as follows;
F = qvB
<h3>Centripetal force of the charge</h3>
The centripetal force experienced by the charge is calculated as follows;
<h3>The magnetic force is equal to the centripetal force</h3>
<h3>The radius of the track</h3>
The radius of the track is calculated as follows;
Thus, the radius of the track in the circular motion is 0.164 mm.

Answer:
A) Air
Explanation:
In refrigerator system the compressor will compress the gas at high pressure so that its temperature is too small and if is passed through the air inside the refrigerator.
When this low temperature gas is passed through the air inside the refrigerator then it will extract the heat from the space or air at high temperature and hence it is the source of energy inside the refrigerator.
Heat pumps are used in in cold atmosphere where we require thermal energy to keep the temperature high. Here compressor will work on the gas so that it will absorb the heat from surrounding air and release it to the room or inside space.
So here in both cases the source of energy here is Air which will give heat to the system.
