The ultimate source of electromagnetic waves are the radio sets. The answer is letter C. <span>One example of an
electromagnetic radiation is the visible light. And visible light can be radio
waves, infrared light and X - rays. The rays of the sun are a form of visible
light. It has an electromagnetic radiation of UV (ultra violet) rays. That is
why the radiation at day is greater than at day due to sun’s rays.</span>
Since the plant is falling, the gravitational energy decreases, so it means b) kinetic energy is increasing.
Hope this helps!! :)

When touching the bar magnet ,the nail gets attached to the magnet from its metallic field is used to connect when taylor touched the nail to the bar magnet,the magnetic fields were ranged,and made a temporary magnet.
Explanation:
Answer:
the conversion of matter into energy
Explanation:
A nuclear reaction is a reaction in which there is a change in the nuclei of the atoms involved. The two most important examples of nuclear reactions are:
- Nuclear fission: it occurs when a heavy, unstable nucleus breaks apart into two or more lighter nuclei
- Nuclear fusion: it occurs when two lighter nuclei fuse together into a heavier nucleus
In both cases, the total mass of the final products is smaller than the total mass of the initial nuclei: this means that part of the mass of the initial nuclei has been converted into energy, according to Einstein's formula:

where
is the variation of mass and c is the speed of light. Since the value of c is very large, we can see from the formula that even a small amount of
is able to produce a huge amount of energy, and this is a typical feature of any nuclear reaction.
