Suppose that plutonium-239, a major nuclear waste product, has major absorption lines at 0.62 micrometers and 1.37 micrometers, with many other minor absorption lines. Using what you know about spectroscopy, describe how such waste disposal in a star could leave lingering evidence in space, even in distant galaxies.

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius ν
=0.381meters and mass ν=3.1νν. initially ν"is on the ground and ν#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of ν#just before it strikes the ground. assume the pulley bearing is frictionless.
