Five different forces act on an object. is it possible for the net force on the object to be zero? explain

Of course it is !

-- Whatever the resultant of four of the forces is, one more force
with the same magnitude in exactly the opposite direction makes
the overall net force zero.

-- Example: 
4 cheerleaders are in a tug-of-war against the captain of the football team.
The flag in the middle of the rope is stationary.
He's holding off all 4 of the skinny girls.
The net force on the flag is zero.

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.
