1.

It is more comfortable to sit on a bed than on a force

Answer»

we KNOW that

P=\frac{F}{A}

this shows that if PRESSURE is inversly proportional to the area

this means that if area is increased, then pressure will AUTOMATICALLY decrease

now, on a bed, area is more, i.e., we COVER a larger area while we sit on bed; as compared to other places, therefore pressure applied is less, and thus we comfortably sit on a bed
