State the laws of simple pendulum?

Law of Length: The time period of the simple pendulum is directly proportional to the square root of its length. ... The oscillation of the simple pendulum is isochronous. Law of gravity: The time period of a simple pendulum is inversely proportional to the square root of the acceleration due to gravity at that place.

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
