A 6.0 V battery is connected to a wire made of three segments of different metals connected one after another: 10 cm of copper wire, then 13 cm of iron wire, then 19 cm of tungsten wire. All of the wires are 0.26 mm in diameter. Find the potential difference across copper wire. Find the potential difference across iron wire Find the potential difference across tungsten wire.
Throughout three hours one winter afternoon, when outside temperature was 9° C, a house heated by electricity was kept at 21° C with the expenditure of 46kwh (kilowatt•hours) of electric energy.
A vessel whose walls are thermally insulated contains 2.00 of water and 0.550 of ice, all at a temperature of 0.0. The outlet of a tube leading from a boiler in which water is boiling at atmospheric pressure is inserted into the water.
Sally travels by car from one city to another. She drives for 30.0 min at 69.0 km/h, 37.0 min at 34 km/h, and 54min at 74.0 km/h and she spends 13.0 min eating lunch and buying gas.
A panicular spring has a spring constant of 86 N/m and a mass of 0.548 kg at its end. When the spring is driven in a viscous medium, the resonant motion occurs at an angular frequency of 12.2 rad/s.
