1. A global positioning satellite
transmits a radio wave with
a wavelength of 19 cm. What is
the frequency of the radio wave?
(Hint: Convert the wavelength
to meters before calculating
the frequency.)

19/100 m/sec Is the answer

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
