Answer:
Explanation:
Let the hails are coming down with speed "v" and then rebound with the same speed in opposite direction
So here the change in the momentum of the hails is given as
now we know by Newton's 2nd Law
here we have
now plug in all data

His weight on the moon would be less due to gravity and i also believe during your time under little gravity your spine decompresses so you get taller <span />
Answer:
Explanation:
The process is isothermic, as P V = constant .
work done = 2.303 n RT log P₁ / P₂
= 2.303 x 5 / 29 x 8.3 x 303 log 2 / 1 kJ
= 300.5k J
This energy in work done by the gas will come fro heat supplied as internal energy is constant due to constant temperature.
heat supplied = 300.5k J
specific volume is volume per unit mass
v / m
pv = n RT
pv = m / M RT
v / m = RT / p M
specific volume = RT / p M
option B is correct.
