Arear window defroster consists of a long, flat wire bonded to the inside surface of the window. when current passes through the wire, it heats up and melts ice and snow on the window. for one window the wire has a total length of 12.0 m, a width of 1.8 mm, and a thickness of 0.12 mm. the wire is connected to the car's 12.0 v battery and draws 12.0 a. what is the resistivity of the wire material?

Asap and show ! a 14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
