Question

2. Mars is currently 35.8 million miles away from Earth. How long would it take to send a radio signal to the Curiosity rover on Mars and receive an answer from the rover, assuming that the rover answers instantly? In other words, what is the round trip travel time for an electromagnetic wave to Mars right now? Recall that c = 3.00 x 108 m/s. Also, 1 mile = 1.61 km. Answer in minutes. 13

Answer 1

an Aim: to determine the sound trip travel time for electro- magnetic wave to mars. Answer: Given information, distance between Mars and Earth is da 35.8 million miles (1 million = 106) = 35.8 X10 x 106 miles I mile = 1.61 km :, di (35.8 x 1.612 x 100 km 6 i. d = 57.638 *10 km 1 km = 103 m 57,63x10 m For the sound taip (9 journey to one and back again). distence covered by the gydio signal will be ad = I 2x 57.63 x10 m 9 115.26 X10 m Radio waves move at the speed of light. Speed of light ca 3x109 mis

as we know that, Speed - distance time 20 t solving for 'time ť, 20 с 9 t 115.26x10 3*108 :. t 384. 2. seconds I minute 60 seconds .: t I (384.2) minutes 60 :It 6.403 minutes. for The sound trip travel time to Mars is 6.403 minutes. an electro-magnetic wave
