While describing a circular orbit 300 mi above the earth a space vehicle launches a 6000-lb communications satellite. Determine the additional energy required to place the satellite in a geosynchronous orbit at an altitude of 22,000 mi

Explanation:

While the satellite is in the space vehicle, it has the next potential energy

             where G is the gravitational constant

                         m is the satellite's mass in kilograms

                        Me is the earth's mass

                        r is the orbit's radius from to the earth's center in meters

The additional energy required is the difference between this energy and the energy that the satellite would have in an orbit with an altitude of 22000 mi

Then

a, c, d, e are all applying about success strategies.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
