First law is Conservation of Energy
Second is that entropy of an isolated system will always increase with time.
Entropy is the change of disorder through time. The best statement which relates to the 2nd law is C. Thermal energy flows from areas of higher to lower temperature
Since the process occurs at constant pressure, the work done by the gas on the piston is given by

where
W is the work
p is the pressure

is the final volume

is the initial volume
In our problem, we have



(where the negative sign means the work is done by the piston on the gas)
We can re-arrange the previous equation and use these values to find the pressure:
Answer:
Height of tower = 480 meter
Explanation:
Given:
Initial velocity = 20 m/s
Time taken to reach ground = 8 second
So,
Final velocity = 0 m/s
Acceleration due to gravity = 10 m/s²
Find:
Height of tower
Computation:
s = ut + (1/2)(g)(t)²
s = (20)(8) + (1/2)(10)(8)²
s = 160 + (1/2)(10)(64)
s = 160 + (10)(32)
s = 160 + 320
s = 480 meter
Height of tower = 480 meter
