When performing an. experiment similar to millikan's oil drop, a student measured the following load magnitudes: 3.26x10 ^-19 c 5.09x10 ^-19 c 1.53x10 ^-19 c 6.39x10 ^-19 c 4.66x10 ^-19 c i used these measurements to find the charge on the electron

Acoal-fired plant generates 600 mw of electric power. the plant uses 4.8 x 10^6 kg of coal each day, and the heat of combustion of coal is 3.3x 10^7 j/kg. the steam that drives the turbines is at a temperature of 300° c, and the exhaust water is at 37° c. (a) what is the overall efficiency of the plant for generating electric power? (b) how much thermal energy is exhausted each day? (c) what is the change in entropy of the universe for this heat engine? (d) using the same heat reservoirs, what is the maximum possible (carnot) efficiency for a heat engine?

Immediately upon reaching its lowest point, a falling pendulum bob has its greatest amount of energy, which is the initial amount of potential energy. a. heat; less than b. heat; more than c. kinetic; less than d. kinetic; more than

What is part of a line has one endpoint and continues in one direction?
