Awire is made from a material having a temperature coefficient of resistivity of 0.0003125 (°c^-1). in an experiment, we maintain a constant potential difference of 150 volts across the wire and measure the power dissipation in it as a function of temperature ; at a temperature of 20° c, the power dissipation is 300 watts. what is the (%) change in the power dissipation as the wire's temperature rises from 20°c to 1820°c?

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
