A spring of equilibrium length L1 L 1 and spring constant k1 k 1 hangs from the ceiling. Mass m1 m 1 is suspended from its lower end. Then a second spring, with equilibrium length L2 L 2 and spring constant k2 k 2 , is hung from the bottom of m1 m 1 . Mass m2 m 2 is suspended from this second spring. Part A How far is m2 m 2 below ceiling

While standing outdoors one evening, you are exposed to the following four types of electromagnetic radiation: yellow light from a sodium street lamp, radio waves from an am radio station, radio waves from an fm radio station, and microwaves from an antenna of a communications system. rank these type of waves in terms of increasing photon energy.

Suppose that 27 j of work is needed to stretch a spring from its natural length of 6 m to a length of 9 m. (a) how much work is needed to stretch the spring from 12 m to 14 m? j (b) how far beyond its natural length will a force of 78 n keep the spring stretched?
