Answer:
Alpha, beta, and gamma particles
Explanation:
A shield of aluminium can effectively block off any form of radiation be it alpha, beta or gamma particles.
Radiations are products of nuclear reactions. These radiations produced are quite harmful and injurious to life.
A thick and appropriate material must be used to block off these radiations so as to properly interact with them in an advantageous way.
A shield of aluminium, a block of lead and any material with a high thickness and density is appropriate for neutralizing these forms of radiation.
Answer:
b energy is being released from the atoms
Explanation:
Seeing light from fireworks implies that energy is being released from the atoms. This is an excitation as the electrons within the atom moves from a higher energy level to a lower energy level.
- When electrons undergo this kind of transition, energy is released.
- The radiation produced is dispersed out and it is seen as colorful lights.
- Most times such processes are exothermic
the produce would be water and some form of salt
hope this helps
