In introductory physics laboratories, a typical Cavendish balance for measuring the gravitational constant G uses lead spheres with masses of 1.10 kilogram and 11 gram whose centers are separated by about 6 centimeter. Find the gravitational force between these spheres, treating each as a particle located at the center of the sphere.
A diffraction grating with 280 lines per mm is used in an experiment to study the visible spectrum of a gas discharge tube. At what angle from the beam axis will the first order peak occur if the tube emits light with wavelength of 400.0 nm? At what ..
