Two particles with masses m and 3m move towards each other with the same initial speed vi. after the elastic collision the particle m moves to 900 from the original direction. a. find the speed of the particles after the collision. b. what is the angle of the particle 3 m after the collision relative to its direction original movement?

small = small current large mag large current

c) up

hope this

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
