Describe two reasons why an alpha particle is less penetrating than a beta or gamma particle.

Explanation:

Alpha particles are less penetrating than a beta or gamma particle. Alpha particles are doubly charged helium nuclei. It consists of two neutrons and two protons.

The penetration of any ray is given by the following relation :

T = e^-u * L

Where

T is the transmittance of any material

u is the coefficient of penetration

L is the length of penetration

The mass and charge of alpha particle is more as compared to beta and gamma particles. They can produce ions easily. So, they penetrate more when compared to beta and gamma rays.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
