Consider a cylinder with water filled to a height of 50 cm. at a height of 10 cm is a hole in the side of the cylinder . assuming that there is no viscous drag of the fluid flowing through the hole, what is the velocity of the fluid squirting out of it? (hint: you will need to use bernoulli, and make the assumption that the pressure of the water just as it leaves the hole, since it is in contact with the air, is just atmospheric pressure.)

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.
