Weather Satellites

Please help - need answer for tom.

The weather pictures on TV come from a spacecraft in a stationary position relative to the surface of Earth, 35700 km above Earth's equator. Explain how it can stay exactly the sameposition day after day. What would happen if it were closer?

Thanks

when the satellite is put in orbit, it is put in such a way that its angular velocity is the same as that of the earth, so it stays 'stationary'.
