Answer:
It is the force that opposes motion between two surfaces touching each other. ( OR ) The force between two surfaces that are sliding or trying to slide across each other.
Explanation:
Internal energy is<span> the </span>energy<span> associated with the random, disordered motion of molecules. This energy </span><span>can not be transferred. whereas. </span>thermal energy<span> is the </span>energy<span> due to temperature </span>difference<span>. </span>
Thermal energy<span> is the </span>energy that comes due to temperature difference. It comes from heat generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated.
The relationship between the heat, the internal energy and the thermal energy is the motion, whether of molecules (internal energy) or of particles (thermal energy).
Answer:
Newton' second law and third law describes the situation.
Explanation:
According to the Newton's second law, the force applied on a body is proportional to the rate of change of momentum of the body.
According to the Newton's third law, for every action there is an equal and opposite reaction.
When ice skater pushes harder means more force is applied so he moves fast and more be the action force more be the reaction force.
Thus, Newton' second law and third law describes the situation.
The radius of the track in the circular motion is 0.164 mm.
<h3>Magnetic force of the of charge</h3>
The magnetic force of the charge is calculated as follows;
F = qvB
<h3>Centripetal force of the charge</h3>
The centripetal force experienced by the charge is calculated as follows;
<h3>The magnetic force is equal to the centripetal force</h3>
<h3>The radius of the track</h3>
The radius of the track is calculated as follows;
Thus, the radius of the track in the circular motion is 0.164 mm.
