How to know 1 light year?me..

Explanation:

one light year is the distance traveled by the light in 365.25 days. Thus,

1 year is 365.25 days.

1 day is 24 hour

1 hour is 60 minute

1 minute is 60 second

thus, 365.25*24*60*60 is 31557600 second.

1 light year is approximately 9.4607 trillion km

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
