Ayudenme con esto porfavor es para un examen! Se muestra un objeto sumergido en agua y en reposo. Considerando que la densidad del objeto es 0,750 g/cm3, Determine: a) La masa del objeto, considerando el volumen del cuerpo igual a 700 cm3. b) La magnitud de la fuerza de empuje sobre el objeto, usando el resultado de la parte A.(g=9,81m/s2) c) El volumen sumergido del objeto.

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?
