Alpha particles consist of two protons and two neutrons bound together into a particle identical to a helium nucleus. they have much less energy than either beta particles of gamma waves. suppose a geiger counter was placed 10 cm from an alpha emitter, and clicks were recorded for three minutes.

a) 0 clicks
b) 2 clicks
c) 5 clicks
d) 10 clicks

0 clicks would be detected on the far side of the aluminum shield. Alpha particles are not very penetrating. Paper, clothing or a few centimeters of air can effectively shield against alpha particles. However, if ingested or inhaled, alpha particles can be hazardous.

Explanation:

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
