The photo shows a pair of figure skaters performing a spin maneuver. The axis of rotation goes through the left foot of the skater on the left. What
change could the pair make that would result in no change to their angular
velocity?
O A. The skater on the right extends her left leg to the right.
B. The skater on the left allows the distance between the pair to
increase.
O C. The skater on the left pulls the skater on the right closer to him.
D. The skater on the left points his right arm down instead of 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
