Gas in a cylinder similar to the one shown in the figure moves a piston with area 0.223 m2 as energy is slowly added to the system. If 2.80 103 J of work is done on the environment and the pressure of the gas in the cylinder remains constant at 1.01 105 Pa, find the displacement of the piston.
Much of the material making up Saturn's rings is in the form of tiny dust grains having radii on the order of 10-6 m. These grains are located in a region containing a dilute ionized gas, and they pick up excess electrons. As an approximation, sup..
A light bulb is connected to a 260V potential, and produces 120-Watts of light and heat. What is the resistance of the wire in the light bulb and how much current does it sends through the heart
