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

The specific heat capacity of the calorimeter used in mixing the water is determined as 21.87 J/g⁰C.
<h3>Conseervation of energy</h3>The heat capacity of the calirometer is determined by applying the principle of conservation of energy.
Heat lost by the hot water = Heat gained by the calirometer
where;
- M is mass
mass = density x volume = ρV
Density of water = 1 g/ml
Mass of hot water = 1 x (50) = 50 g
Mass of water in calorimeter = 1 x (60) = 60 g
<h3>Equilibrium temperature</h3>Thus, the specific heat capacity of the calorimeter used in mixing the water is determined as 21.87 J/g⁰C.
