Name the following Orbits of a satellite between 180 km to 2000 km from earth's surface.

Calculate the K.E, P.E, Total energy and Binding energy of an artificial satellite of mass 2000kg orbiting at a height of 3600 km above the surface of the earth Given: G = 6.67 xx 10^-11 Nm^2//kg R= 6400 km= 6.4 xx 10^6 m M= 6 xx 10^24 kg m = 2000 kg h = 3600 km = 3.6 xx 10^6 m

A train approaching a station reduces its speed from 180 km/hr to 90 km/hr. If the mass of the train is about 20,000 kg then how much is the work done by the train?

Find the gravitational potential energy of a body of mass 10 kg when it is at a height of 6400 km from the earth's surface. [M (earth) = 6xx 10^24 kg, R(earth) =6400 km]

Solve the following questions : If the truck traverses the 10km distance AB in 10 minutes, BC in 20 minutes and CD in 30 minutes , then velocity for the distance AB in km/hr = (10 km / 10 minutes) = (60 km / 60 minutes) = 60 km/hr : Now deduce the velocities for the distances BC and CD .
