Two point charges are fixed on the y axis: a negative point charge q1 = -25 μc at y1 = +0.18 m and a positive point charge q2 at y2 = +0.34 m. a third point charge q = +8.4 μc is fixed at the origin. the net electrostatic force exerted on the charge q by the other two charges has a magnitude of 25 n and points in the +y direction. determine the magnitude of q2.

The characteristics of groundwater is said to be: are weak turbiditya constant temperaturechemical composition and almost overall absence of oxygen.

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.
