An amateur scientist directs a radio signal pulse at Mars, which is 1.5 x 10m away at the time. Then, 800 seconds later, while peering through a telescope, she observes an explosion on Mars. Could the explosion somehow have been caused by her act of sending the radio pulse?

    No.

    Explanation:

    A radio wave is an electromagnetic wave and all electromagnetic waves move at the speed of light, 3 * 10^8 m/s.

    We can find the time it will take for the signal to get to Mars from Earth:

    Time = distance/speed

    Time = (1.5 * 10^11) / (3 * 10^8)

    Time = 500 secs

    Hence, it would be impossible for the explosion (which occurs 300 secs later) to have been caused by her radio signal pulse.
