Question

A radar signal is beamed towards a planet and its echo is received 7 minutes later. If the

distance between the planet and the earth is 6.3 x 1010 m. Calculate the speed of the

signal.​

Answer 1

Explanation:

T = 7/2

$s \: = 6.3 \times{10}^{10}$

v = 6.3×10^10/7/2

= 1.8×10^10

Therefore the speed of the signal is 1.8×10^10m/s
