Q. The rotational inertia of a collapsing spinning star changes to 1/3 its initial value. What is the ratio of the new rotational kinetic energy to the initial rotational kinetic energy (KEnew / KEi)?

Q. A collimated beam of microwaves impinges on a metal screen that contains a long horizontal slit that is 20 cm wide. A detector moving parallel to the screen in the far-field region locates the first minimum of irradiance at an angle of 36.87° above the central axis. Determine the wavelength of the radiation.
