The inertial frame has:
Correct answer: D. All of these
- A. Constant velocity
- B. Zero velocity
- C. Zero acceleration
- D. All of these
Explanation
An inertial frame can indeed have objects with constant velocity, zero velocity, and zero acceleration. These characteristics are all consistent with the definition of an inertial frame, which is a reference frame in which Newton's laws of motion are valid and where objects not subject to external forces move with uniform velocity or remain at rest.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
