Answer
given,
time of disk stayed a loft = 16.7 sec
height reached = 18.4 m
mass = 72 kg
now work done is equal to change in potential energy
W = 12983.04 J
Positive sign means that work is in the direction of motion.
P = 777.42 Watts
Work done per unit time :- a. force b. power c. energy d. momentum

Answer:Decreases
Explanation:
Given
Volume is held constant that is it is a isochoric process.
We know that
PV=nRT
as n,V& R are constant therefore only variables are
P & T
so
As is decreasing therefore Pressure must also decrease so that ratio remains constant.
