A negative charge of -4.0 x 10 -6 C and a positive charge of 7.0 x 10 -5 C are separated by 30 cm. What is the force between the two charges?

Agas expands from an initial volume of 0.040 m^3 and an initial pressure of 210 kpa to a final volume of 0.065 m^3 while its temperature is kept constant. how much work is done by the system?

The nuclear potential that binds protons and neutrons in the nucleus of an atom is often approximated by a square well. imagine a proton conned in an innite square well of length 105 nm, a typical nuclear diameter. calculate the wavelength and energy associated with the photon that is emitted when the proton undergoes a transition from the rst excited state (n 2) to the ground state (n 1). in what region of the electromagnetic spectrum does this wavelength belong?

When flexing to a reflective style, one should be specific, brief and to the point, and maintain a fast and decisive pace?
