Q: Hubble's law is related to ...............
  • A. Heat
  • B. Sound
  • C. Astronomy
  • D. Pressure of wind
Correct Answer: Option C - Hubble's law is related to astronomy. Hubble showed that galaxies are receding away from Earth with a velocity that is proportional to their distance from Earth. More distant galaxies recede faster than nearby galaxies. Hubble's law is used for understanding the motion of the astronomical objects due to the expansion of the universe.
