Answer:
Electrons
Explanation:
Ionised atoms loose and gain electrons.
hope it helps!
Answer:
the action of polarizing or state of being or becoming polarized: such as the action or process of affecting radiation and especially light so that the vibrations of the wave assume a definite form. Polarization, in Physics, is defined as a phenomenon caused due to the wave nature of electromagnetic radiation. There are two types of waves, transverse waves, and longitudinal waves.

Answer: the same as Lily's
Explanation:
Angular velocity has to do with the speed at which an object will be able to rotate. We are informed that Bob and Lily are riding on a merry-go-round.
Since we are further told that Bob rides on a horse near the outer edge of the circular platform, and Lily rides on a horse near the center of the circular platform and that he merry-go-round is rotating at a constant angular speed.
Based on the above analysis, Bob's angular speed will be thesame as that of Lily.

The energy that the man has gained in being lifted is 3000J which is in the form of potential energy.
<u>Explanation:</u>
Given:
Work done, W = 3000J
Height, h = 2.5m
Time, t = 0.4 seconds
Energy gained = ?
As the man gets lifted, it gains potential energy.
Potential energy will be equal to the work done by the elevator.
We know,
potential energy = mgh
Thus, the energy that the man has gained in being lifted is 3000J which is in the form of potential energy.
