Explanation:
From the question we are told that:
Bowling ball Speed
Beach ball Speed
Let The Mass be equal i.e
Therefore
Generally the equation for Velocity of beach ball after collision is mathematically given by
Since Velocity is Vector Quantity
Therefore
The heat required to change 1.25 kg of steak is 2825 kJ /kg.
<u>Explanation</u>:
Given, mass m = 1.25 kg, Temperature t = 100 degree celsius
To calculate the heat required,
Q = m L
where m represents the mass in kg,
L represents the heat of vaporization.
When a material in the liquid state is given energy, it changes its phase from liquid to vapor and the energy absorbed in this process is called heat of the vaporization. The heat of vaporization of the water is about 2260 kJ/kg.
Q = 1.25 2260
Q = 2825 kJ /kg.
