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?

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
