Aman (mass=68 kg) on a parachute is falling at terminal velocity (v=59 m/s)
at which rate do the internal energy of the man and of the air around him increase?

Explanation:

It is given that,

Mass of the man, m = 68 kg

Terminal velocity of the man, v = 59 m/s

We need to find the rate at which the internal energy of the man and of the air around him increase. The gravitational potential energy of the man is given by :

Differentiating equation (1) wrt t as :

Since,

So, the internal energy of the man and the air around him is increasing at the rate of 39317.6 J/s. Hence, this is the required solution.

gans

explanation:

vestigial organs (like your appendix) are organs that no longer serve a purpose.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
