Which statement best summarizes niels bohr's complementarity principle? light incident on a metal surface results in the emission of a photon. light incident on a metal surface results in absorption of energy. the wave theory and the particle theory of light coexist. the theory of wave-particle duality does not hold true.

The complementarity principle says that when one wishes to study the behavior of light on an atomic scale, the wave and particle natures of light must both be observed simultaneously to present a more complete overall description.(On the other hand, when observing light on a macroscopic scale, one does not typically need to consider both wave and particle natures simultaneously.)

hope this

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
