Estimate the change in gravitational potential energy when a person with mass 80 kg rise from bed to a standing position. Assumi
Doss [256]

Answer:

change in gravitational potential energy Δ PE = 392 J

Explanation:

given data

mass of the person m  = 80 kg

height of the centre of mass Δh = 0.50 m

to find out

change in gravitational potential energy

solution

we get here change in gravitational potential energy that is express here as

change in gravitational potential energy Δ PE = m × g × Δh     .........1

put here value we get

change in gravitational potential energy Δ PE = m × g × Δh

change in gravitational potential energy Δ PE = 80 × 9.8 × 0.50

change in gravitational potential energy Δ PE = 392 J

A man weighing 750 n and a woman weighing 500 n have the same momentum. what is the ratio of the man's kinetic energy km to that
miss Akunina [59]
Because weight W = M g, the ratio of weights equals the ratio of masses.

(M_m g)/ (M_w g) = [ (p^2 Man )/ (2 K_man)] / [ (p^2 Woman )/ (2 K_woman)

but p's are equal, so

K_m/K_m = (M_w g)/(M_m g) = W_woman / W_man = 450/680 = 0.662

Why is Saturn almost as big as Jupiter, despite its smaller mass?
gulaghasi [49]

Answer:

c. Jupiter's greater mass compresses it more, thus increasing its density.

Explanation:

The mass of Jupiter is greater in its interior, this mass compresses Jupiter to some extent. Thus, its density is increased. Now, more mass is compressed in the lesser volume. Hence, its size does not increase enormously. On the other hand the mass of Saturn is lesser  and also density lower. this gives Saturn a reasonably higher volume.

Hence, option C is correct.
