A space probe of the surface of Mars sends a radio signal back to the Earth, a distance of 3.91 x 108 km. Radio waves travel at the speed of light (3.00 x 108 m/s).(a) How far away is the space probe?(b) How many seconds does it take for the signal to reach the Earth?(c) How many hours is this?
The distance between Saturn and the sun is approximately 8.9 × 108 mi. The speed of light is approximately 1.9 × 105 miles per second.
How long does it take light to travel from the sun to Saturn? Answer in units of sec.
The speed of light is 3 x 108 m/s. If it takes sunlight 8 minutes to reach earth, how far away is the sun?

Charged pions are unstable particles that decay into muons with a half-life of 1.8 x 10-8 s.
