$(78)$
​

Answer 1

Explanation:

We know that pressure=force/area. When the string of the school bag is thin, its area is small and as such the pressure exerted on shoulders or the hands supporting the bag is large. In this case, the force acting on the shouldfers or the hand which support the bag is equal to the weight of the bag.

Answer 2

Answer:

It is difficult to hold a school bag having a strap made of thin and strong string, because the thin string has very less contacting area in case of a school bag having a strap made of thin and strong string which increases pressure which is un comfortable to carry the school bag.
