You are originally 1.0 m beneath the surface of a pool. if you dive to 2.0 m beneath the surface, what happens to the absolute pressure on you?
a. it does not change.
b. it less than doubles.
c. it more than doubles.
d. it quadruples.
e. it doubles.

It less than doubles.

Explanation:

It is given that,

You are originally 1.0 m beneath the surface of a pool, h = 1 m

If you dive to 2.0 m beneath the surface, h' = 2 m

The absolute pressure acting on the person is given by :

is the atmospheric pressure

If h = 1

If h = 2

When the height becomes doubles, the absolute pressure on you becomes less than doubles. Hence, the correct option is (B).

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
