proof
A parallel beam of light is incident normally on a plane surface absorbing 40% of the light and reflecting the rest . If the incident beam carries 10W of power , find the force exerted by it on the surface .
A certain rifle bullet has a mass of 8.61 g. Calculate the de Broglie wavelength of the bullet traveling at 1289 miles per hour. Physical constants can be found here.
