- How many meters are there in 3.2 light year (s), if the speed of light is 3 x 108 m/s. This number may be very large so do not round or truncate your number. Answer:A space probe with a diameter of 2.50m is moving past Saturn's moon Enceladus. An observational platform on Enceladus measures the shortest length of the ellipsoidal probe to be 1.25m. How fast is the probe moving relative to the moon? a) .999c b) .995c c) .957c d) .883c e) .866cHow many years older will you be 1.30 billion seconds from now? (Assume a 365-day year.) dont provide handwritten solution
