Explanation:

When a person is vertically standing on a cushion the body weight is applied downward with gravitational force acting upon the body hence all the weight is applied to the cushion. Whereas when a person is lying down all the weight is transmitted equally, so all the weight is not on a specific part hence applying less weight to the cushion. Thereby, the depression is more while standing compared to when lying down.

It can be taken in a force and pressure sense, the it would be that the area of cross-section while standing is less, hence the pressure is more whereas the area of cross-section is more while lying hence pressure it

Answer:

1

as we know pressure equals force divided by area

so when we sit on the sofa then force is on one side and muchmore then when we sleep on so only the situation exists

2 the question is wrong

because weightlifter apply powder in their hands before weightlifting this is done to increase friction of hands so that he can grab it easily
