Explanation:
When a radioactive substance decays then the fast moving electrons emitted by it is known as beta ray. Basically, a number of beta particles are ejected by a beta ray.
Symbol of a beta particle is . A beta ray is a natural decay of a radioactive element. As we know that opposite charges get attracted towards each other. So, a beta ray gets attracted towards a positively charged plate.
Therefore, we can conclude that following are the characterizes a beta ray:
- a product of natural radioactive decay.
- is attracted to the positively charged plate in an electric field.
- is composed of electrons.
A. Lowering the temperature.
because I googled it and are you going there or something
A. The potential energy is always the highest at the top and the kinetic energy is always the lowest at the top.
