1. Suppose you're working at a constant temperature , when you exert more pressure on an object
vova2212 [387]

Answer:

Decrease

Explanation:

Working at a constant temperature when more pressure is exerted, the volume decreases.

This is known as Boyle's law.

 According to Boyle's law;

       "the volume of a fixed mass of a gas varies inversely as the pressure changes, if the temperature is constant".

  Mathematically;

          P₁V₁  = P₂V₂

P and V are pressure and volume

1 and 2 are initial and final states.

When Danny Diver who weighs 500 N steps off a diving board 10 m above the water, he hits the water with kinetic energy of
Andreas93 [3]

Answer:

5000 J

Explanation:

Given that,

Weight of Danny Diver, F = 500 N

He steps off a diving board 10 m above the water

We need to find the kinetic energy of the water with which it hits. Let its is K. It is given by :

E = mgh

Where g is acceleration due to gravity

E=500\ N\times 10\ m\\\\=5000\ J

So, he hits the water with kinetic energy of 5000 J.
