The aging process of the human body is slowed by motion at:
Correct answer: C. Very high speed along a circular path
- A. Very slow speed
- B. Very high speed
- C. Very high speed along a circular path
- D. None of these
Explanation
This is based on the concept of time dilation from Einstein's theory of relativity. When an object moves at a very high speed, especially near the speed of light, time appears to pass more slowly for that object relative to a stationary observer.

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.
