a lightyear
100km is a distance, not a measurement of time. (kilometres)
Accurate measurements of time become possible after accurate measurement of length and mass because time taken by a heavy body to move a certain distance is more,and time taken by a light body to move a certain distance is less.
Measurement always deals with a distance of a line or a distance between to objects, distance between 2 points, and so on.
A minute is a measurement of time. A light minute is a measurement of distance. it's the distance light would travel in one minute. (That's about 10 million miles!)
Yes.
a mega lightyear
A lightyear is a unit of distance, not time. It represents the distance that light can travel in one year, which is about 5.88 trillion miles.
Lightyear isn't about time, it's distance. One lightyear is ten trillion kilometers.
A lightyear is a much larger distance.
a lightyear
"Lightyear" is a noun. It is a unit of distance used to measure interstellar space.
None, a furlong is a measurement of distance, and a year is a measurement of time.
Hour = measurement of time. Miles = measurement of distance.
100km is a distance, not a measurement of time. (kilometres)
a Lightyear, around 1013 kilometres.
buzz lightyear (FTW!)
