Answer:
Explanation:
Charles law states that "the volume of a fixed mass of gas varies directly as its absolute temperature if the pressure is constant".
This law is a derivative of the kinetic molecular theory of gases.
- The law explained shows that as the temperature of gases increases the volume of gases increases.
- When gases are heated the average kinetic energy of the molecules increases.
- The molecules are independent of one another and they begin to expand out as their velocity surges.
- They take up more spaces in this way.
The object will speed up and start to spin in different directions.
C. air, fire, water, earth. 4 elements
43.62m
Explanation:
Given parameters:
Energy = 8550J
Mass of bell = 20kg
Unknown:
Height of the bell = ?
Solution:
As this state, the bell possesses potential energy. Potential energy is the energy at rest in a body. It is due to the position of the body.
Potential energy = m g h
m is the mass of the body
g is the acceleration due to gravity of the body
h is the height of the body
The unknown is h and we should solve for it.
g = 9.8m/s²
Input the variables;
8550 = 20 x 9.8 x h
h = 43.62m
