A 0.25kg arrow with a velocity of 12m/s to the west strikes and gets stuck in the center of a 6.8kg target. What is the impulse of the arrow as it hits the target?

f is prop to m1xm2 double m1 double force

so easy. just google the electromagnetic waves and it’ll pop up.

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
