This problem explores the behavior of charge on conductors. we take as an example a long conducting rod suspended by insulating strings. assume that the rod is initially electrically neutral. for convenience we will refer to the left end of the rod as end a, and the right end of the rod as end b. in the answer options for this problem, "strongly attracted/repelled" means "attracted/repelled with a force of magnitude similar to that which would exist between two charged balls.

a small metal ball is given a negative charge, then brought near (i. e., within about 1/10 the length of the rod) to end a of the rod. what happens to end a of the rod when the ball approaches it closely this first time?

Acar moves a distance of 50.0 km west, followed by a distance of 64.9 km north what was the magnitude of the displacement of the car, in units of kilometers?

Which statement correctly describes the relationship between frequency and wavelength?

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
