A satellite of mass 20 kg is in orbit around the Earth. At the height of the satellite’s orbit, the gravitational field strength is one quarter of its strength on the surface of the Earth. The gravitational field strength on the surface of the Earth is 10 N/ kg. What is the weight of the satellite as it orbits the Earth?

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
