Physical quantities are measured as 'nu' where n is the magnitude and u is the unit. For example: A boy measured the length of a room as 3 m. Here 3 is the magnitude and m (metre) is the unit. 3 m can also be written as 300 cm.
No. The only European units I know of who were able to sustain that. kind of speed on foot were Foreign Legion-where the standard was 50. km per day. Other infantry units usually come in under 20 miles a day. (and closer to 12-15 miles per day).
Gee, that's an easy one! The shuttle or anything in low earth orbit has to travel about 17,500 miles per hour, and that is roughly ten times the speed of a rifle bullet. If you think a rifle bullet is moving fast -- just imagine the orbiter.It's moving about ten times that speed.So that should give you some idea.he shuttle or anything in low earth orbit has to travel about 17,500 miles per hour, and that is roughly ten times the speed of a rifle bullet.
