A charged particle moves between two parallel current-carrying wires, separated by 3cm, in the direction parallelto both of them. CurrentI2is three times larger than currentI1and runs opposite to it. At what distance, x,from the wire carryingI1would the particle be undeflected by the combined magnetic field of the wires?Hint:Thewires do exert force on each other but that is not relevant to this proble

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?

What is the scientific definition of energy that relates to work

Agas expands from an initial volume of 0.040 m^3 and an initial pressure of 210 kpa to a final volume of 0.065 m^3 while its temperature is kept constant. how much work is done by the system?
