How does the brightness of a bulb tell you about the energy of electrons passing through it?

1 answer:

8 0

The brightness of the bulb doesn't tell you anything about the energy of the
electrons passing through it.

It tells you how much total energy is lost by the total flow of electrons through
the bulb. You can't tell what part of that is due to a large or small number of
electrons, or what part of it is due to each electron losing a large or small amount
of energy on the way through.

A large body collides with a stationary small body from the rear end. How do the bodies behave if the collision is inelastic?.

alexdok [17]

If the collision is inelastic, there is every possibility that the large body will drag the small stationary body along with it in the direction of the collision. Some amount of heat, light and sound energy will also be produced due to the kinetic energy of the large body. I hope the answer helps you.

What change occurs to the mass of an object when an unbalanced force is applied to it

strojnjashka [21]

The mass of an object always stays the same since it is really just the amount of matter in an object so no matter the force applied, as long as the object does not lose or gain matter, the object stays the same
