The volume decreases, by a factor of
(the original pressure/(125 kPa).
The layers form from sand dunes
We know, Potential Energy = Force * Height
Here, F = 40 N
h = 5 m
Substitute their values,
U = 40 * 5
U = 200 J
In short, Your Answer would be Option A
Hope this helps!
Well, F = ma
and a= change in vel / change in time
= (2-0 ) / 1 = 2 m^2/s
so, F= 4* 2 = 8 N
and W = F.S = 8 * 2 = 16 J
hope it helped
It would be 5 mph. Hope it helps! :)
