Answer:
5 m
Explanation:
30 m/s / 6.0 cycles/s = 5 m/cycle
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.
ANY force at all, acting in the right direction, will stop him.
But smaller forces will take longer.
In order to either speed him up or slow him down at the rate
of 20 m/s every second, the force required is
(mass) x (acceleration) = (120 kg) x (20 m/s²)
= (2400 kg-m/s²) = 2400 N .
The force can either increase or decrease his speed at that rate,
depending on the direction in which it acts on him.
If the force is exerted opposite to the direction in which he's already
moving, then it can stop him if it continues long enough.
