P073 The weight of a star is usually balanced by two forces: the gravitational force, acting inward, and the force created by nuclear reaction, acting outward. Over a long period of time, the force due to nuclear reactions gets weaker, causing the gravitational collapse of the star and crushing atoms out…
radius, problem A machinist with normal vision has a near point at 25 cm. The machinist wears eyeglasses in order to do close work. The power of the lenses is +2.25 diopters. With these eyeglasses, the near point of the machinist, in cm, is closest to?a-13 b-19 c-16 d-10 e-22
A machinist with normal vision has a near point at 25 cm? While driving at a constant speed of 80 km/h, you are passed by a car traveling at 124 km/h. If the frequency of light emitted by the taillights of the car that passes you is 4.3 multiplied by 1014 Hz, what frequency will […]
help Bohr radius Muonium Muonium is a hydrogen-like atom in which the electron is replaced with a muon, a fundamental particle with a charge of -e and a mass equal to 207me . (The muon is sometimes referred to loosely as a “heavy electron.”) What is the Bohr radius of muonium? Will the wavelengths in […]
