How many kilometers a pulse from a laser beam travels exactly 3.3 hours (s)?
Use the fact that the speed of light in vacuum is about 3.00 108 m / s to determine how many kilometers a pulse from a laser beam travels exactly 3.3 hour (s).
hello, you have multiply 3 * 10 ^ 8 60 * 3.3 * 60 to get the distance. is our normal speed = distance / time formula. this will give ans in meters or so to divide by 1000 to get at Km Hope that helps!
