mars rover when the mars rover was deployed on the surface of mars in july 1997, radio signals took about 12 min to travel from earth to the rover. part a how far was mars from earth at that time? express your answer using two significant figures.

The distance from Mars to Earth at that time is  2.2x 10¹⁰m. To find the distance, apply the given concept:Since radio signals are a form of electromagnetic wave, so the speed of the wave(v)v= 3x10⁸ m/st= 12 min = 12x 60= 720 sd is the distance between Mars and Earth at that timed=vxtd= 3x10⁸ x720d= 2.16x10¹¹ mTherefore, the distance is 2.16x 10¹¹ m.To answer it in two significant figures, we will have to take an approximate valueSo, the distance is 2.2x 10¹⁰ mTo learn more about distance, visit https://brainly.com/question/1326811#SPJ4
