A satellite orbits the Earth (mass = 5.98 x 1024 kg) once every 43200 s. At what radius does the satellite orbit? Please help, thanks

Could someone . i have tried to solve myself but my calculation is off

Does the earth behave like a magnet how do you prove it

Consider the phase change taking place in the picture. you could use all but one statement to describe what is happening here. that is: a) temperature is increasing. b) kinetic energy is increasing. c) the space between the particles remains the same. d) the attractive force between the particles is decreasing.
