An ice cube slides around a vertical circular path of diameter d. at the top of the circular path, the ice cube is moving at a speed of vt . (a) what is the speed of the ice cube at the bottom of the circular path in terms of given parameters and constants of the universe? (b) find an expression for the ice cube’s speed when it is at an angle θ, where the angle θ is measured counterclockwise from the top of the circular path.

i believe it is b. what was the cause of the big bang

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
