Answer:
The temperature of an object increases when the molecules that make up that object move faster. Thermal energy is energy possessed by an object or system due to the movement of particles within the object or the system.
Answer
given,
I = 0.140 kg ·m²
decrease from 3.00 to 0.800 kg ·m²/s in 1.50 s.
a) 
τ = -1.467 N m
b) angle at which fly wheel will turn
θ = 20.35 rad
c) work done on the wheel
W = τ x θ
W = -1.467 x 20.35 rad
W = -29.86 J
d) average power of wheel
Answer:
There is a localization of negative charge near the door handle.
Based on the scenario,
The thing that the result say about distance covered is :
it tells you that the distance covered is equal to the average speed times the travel time
hope this helps
Answer: Option (a) is the correct answer.
Explanation:
When gases, liquids, or solids are in contact with a moving object then friction occurs due to the movement of objects in opposite directions.
During this opposite movement, bonds between the molecules of respective objects break and again their is formation of new bonds.
This breaking or making of bonds results in the formation of energy in the form of heat.
Thus, we can conclude that when gases, liquids, or solids are in contact with a moving object, the flow of heat occurs due to frictional forces.
