A 1.5 kg pendulum swings from point A of height yA = 0.04 m to point B of height YB = 0.12 m. The heights are relative to the lowest height.

What is the change in gravitational potential energy from A to B?​

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.

Wave functions describe orbitals in a hydrogen atom. each function is characterized by 3 quantum numbers: n, l, and ml. if the value of n = 2: the quantum number l can have values from to . the total number of orbitals possible at the n = 2 energy level is .

The radius of an atom is closest in size to a
