far ultraviolet light with a wavelength of 180 nm is incident on an unknown solid surface, which releases photoelectrons with a maximum speed of 9.10 ✕ 105 m/s.

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy
