    Resistance and Resistivity of tungsten wire

    please check my work someone. A tungsten wire has a radius of .075mm and is heated from 20.0 to 1320 degrees C. The temperature coefficient of resistivity is 4.5x10^-3 (C)^-1. When 120V is applied across the ends of the hot wire, a current os 1.5A is produced. How long is the wire? Neglect...

    Initial Velocity of Diver: Mag & Dir

    Can someone please help me A diver spings upward from a board that is three meters above the water. At the instant she contacts the water he speed is 8.90m/s and her body makes an angle of 75 degrees with respect to the horizontal surface of the water. Determine her initial velocity, both...
