Answer:

  1. (Answer of part B) First of all diameter of Mars in ordinary number = 6780 km
  2. Now radius = Diameter/2
  3. = 6780/2
  4. = 3390
  5. So radius of Mars in ordinary number = 3390 km
  6. (Answer of part C) Mass of earth = 5.97 × 10³⁴
  7. Mass of mercury = 3.3 × 10²³
  8. Difference between the masses of Earth and Mercury = (5.97 × 10³⁴) - (3.3 × 10²³)
  9. = 2.67 × 10¹¹
  10. So, difference = 2.67 × 10¹¹
