From gauss's law, the electric field set up by a uniform line of charge is given by the following expression where is a unit vector pointing radially away from the line and λ is the linear charge density along the line. = derive an expression for the potential difference between r = r1 and r = r2. (use any variable or symbol stated above along with the following as necessary: ε0 and π.)

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.

Idon't know it i just need my points lol
