Well the basic equation for velocity is v=d/t where d is distance and t is time. So v=2m/50s and the answer is v=0.04meter/second.
Answer:
2nd option
Explanation:
Static electricity the charges are at rest and they are accumulating on the surface of the insulator.
Current electricity the electrons are moving inside the conductor.
Answer:
Everything around you is made of matter, including the clothes you wear, the food you eat, and everything you touch. Even the air you breathe is made of matter. Air is a mixture of several kinds of atoms and molecules, including oxygen molecules. Skin is mostly made of collagen molecules.

The thermal energy used by the tires is 1.14 J.
Here, the thermal energy used will be the work done by Mark.
Given,
Distance = 140 m
Force exerted = 160 N
Thermal energy = ?
We know,
Work = force * displacement
But here the thermal energy of tires is asked.
In this question, the thermal energy used is the energy consumed to do the work.
So, using the formula of work we can find the thermal energy.
W = 160 / 140 = 1.14 J
Therefore the thermal energy used by the tires is 1.14J
