Answer:
diameter = 5m
radius = 2.5m
distance in 1 revolution = 2 (pi) r = 2 * 22/7 * 2.5
distance in 3 revolutions = 3* 22/7* 2* 2.5 (we could take the value of 22/7 as 3.14)
= 3* 3.14* 5 = 9.42* 5 = 47.10
as the body comes back to the same position the displacement is 0
Explanation:
Answer:
Acceleration
Explanation:
The quantity of the rate of change of velocity is termed the acceleration of the body.
Acceleration is the rate of change of velocity with time;
A =
A is the acceleration
v is the final velocity
u is the initial velocity
t is the time taken

Answer:
Condenser
Explanation:
The refrigerator work on a simple cycle:
1- When the cold air inside the refrigerator starts to get warm, it loses its thermal energy ot the cold refrigerant which is flowing inside an evaporator. This thermal energy converts the refrigerant into a gas.
2- The refrigerant, in a form of gas, goes to the compressor. The compressor compresses it and increases its temperature even more.
3- Then it goes to the condenser where it loses its most of the thermal energy to the condenser coils. When it loses the energy. it comes back to liquid form.
4.The refrigerant flow back to the evaporator
Cycle continuous
