Astudent solving for the acceleration of an object has applied appropriate physics principles and obtained the expression a=a1+fm where a1=3.00 meter/second2, f=12.0kilogram⋅meter/second2 and m=7.00kilogram. first, which of the following is the correct step for obtaining a common denominator for the two fractions in the expression in solving for a?

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
