Compute the work required to launch a 1000-kg satellite vertically to a height of 1000 km. You may assume that the earth’s mass is 5.98 x 10^24 kg and is concentrated at its center. Take the radius of the earth to be 6.37 x 10^6 m and G = 6.67 x 10^11 Nm2/kg2 .

Explanation:

In order to calculate the work from r = a to r = b we only need to convert 1000 km into 1,000,000 m.

Since, the given data is as follows.

           G =

        = 1000 kg

           a =

           b =

              =

Now, we will calculate the work as follows.

              W =

                   =

                   =

thus, we can conclude that work required to launch the satellite is .

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
