Describe three risks or disadvantages of nuclear
power.

due to the properties of radioactive elements like penetration power and ionization effect they can cause gene mutations, kill living cells and cause cancer. They also have the advantages. They are used to make nuclear energy

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
