the velocity of a car is 15m/s but its velocity is zero. how do you express such a situation of a moving body?​

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.

No because a circle or pie graph usually shows percentages you'd need a line graph

Sorry i don’t know what to do
