The correct answer is A) Gamma rays only

Answer from: yulimariu27

The correct answer is A) Gamma rays only

Answer from: anna4060

Answer : The correct option is, gamma rays only

Explanation :

Penetration power : It is the movement of rays or the particles through an object.

As we know that the more the energy of a particle, the more will be the penetrating power.

The increasing order of the penetration power of alpha rays, beta rays, and gamma rays will be,

Alpha rays < Beta rays < Gamma rays

The penetrating power of the alpha, beta and gamma rays varies greatly.

The alpha particles are restricted by the paper. The beta particles can pass through the paper but it can not pass through the aluminum foil. The blocking of gamma rays is very difficult. It can be blocked only by concrete, lead, or other heavy shielding.

Hence, the radiation can pass through the sheet of metal and hit the target is, gamma rays only.

Evaporation: this is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas). water vapour droplets join together to make clouds! condensation: this is when water vapour in the air cools down and turns back into liquid water.
