An airforce plane is ascending vertically at the rate of 100 km/h. If the radius of the earth is `rk m ,` how fast is the area of the earth, visible from the plane, increasing at 3 minutes after it started ascending? Given that the visible area `A` at height `h` is given by `A=2pir^2h/(r+h)` .

An airforce plane is ascending vertically at the rate of 100km/h .If the radius of the earth is rkm, how fast is the area of the earth,visible from the plane,increasing at 3 minutes after it started ascending? Given that the visible area A at height h is given by A=2 pi r^(2)(h)/(r+h) .

An Airforce plane is ascending vertically at the rate of 100 km/h. If the radius of the Earth is r km, then how fast is the area of the Earth visible from the plane increasing at 3 min after it started ascending ? Given that the visible area A at height h is given by A = 2pi r^(2) (h)/(r + h) .

A air-foce plane is ascending vertically at the rate of 100 km/h. If the radius of the earth is r km, how fast is the area of the earth, visible from the plane, increasing at 3 min after it started ascending? Note Visible area A=(2pir^(2)h)/(r+h) , where h is the height of the plane above the earth.

What is the condition for setting up an artificial satellite at a height h from the earth’s surface? (Radius of the earth = R, mass of the earth= M).

A ball is thrown vertically upwards with a velocity equal to half the escape velocity from the surface of the earth. The ball rises to a height h above the surface of the earth. If the radius of the earth is R, then the ratio h/R is

An earth satellite of mass m revolves in a circular orbit at a height h from the surface of the earth. R is the radius of the earth and g is acceleration due to gravity at the surface of the earth. The velocity of the satellite in the orbit is given by

A geostationary satellite is nearly at a height of h = 6 R from the surface of the earth where R is the radius of the earth. Calculate the area on the surface of the earth in which the communication can be made using this satellite.
