Answer:
9,800 watts
Explanation:
The first step is to calculate the force
F= mg
= 500 × 9.8
= 4,900 N
The next step is to calculate the work done
= 4,900 × 100
= 490,000 joules
Therefore the power can be calculated as follows
Power= work done /time
= 490,000/50
= 9,800 watts

Sorry if this didn't help- I'm not quite sure what you're asking.
Initial volume of the gas (V1) = 10 inches^3
Initial pressure (P1) = 5 psi
Final pressure after compression of the gas (P1) = 10 psi
Let us assume the final volume of the gas (V2) = x
According to Boyle's Gas law, the pressure and volume of a gas remains constant under ideal condition. Then
P1V1= P2V2
5 * 10 = 10 * x
50 = 10x
x = 50/10
= 5 cubic inches
So the volume of the gas after it was compressed was 5 cubic inches. I hope the procedure is clear enough for you to understand.
