If you jumped out of a plane, you would begin speeding up as you fall downward. Eventually, due to wind resistance, your velocity would become constant with time. After this occurs, the magnitude of the force of wind resistance is a. equal to the force of gravity acting on you. b. is slightly smaller than the force of gravity acting on you. c. is much smaller than the force of gravity acting on you. d. is greater than the force of gravity acting on you.

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

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
