Watersheds provide many of us with our drinking water supply, plus recreational opportunities and aesthetic beauty. Watersheds are areas from which water runs into a public water supply. Thus, much of the water you drink from a public source has passed through a watershed. Because of this, it's important that care be taken to minimize any contaminents that may find their way into a public water supply. A small example of a watershed would be the hills around a reservoir. A larger example would be the portions of Pennsylvania, New York, Virginia, Maryland, Delaware and Washington DC that are designated Chesapeake Bay watershed.
This depends entirely on the type of transformation of energy that is taking place, mechanical to thermal, thermal to mechanical, etc. But energy is always conserved, although it may take a different form.
Answer:
15.3 m/s
Explanation:
Radius of orbit= 6400+6300 = 12700 km
Circumference of orbit= 2*(22/7)*12700 =79796.45*10^3 m
Now,
Speed= Distance / Time
= 79796.45*10^3/(24*60*3600)
= 15.3 m/s
