The iceberg kid, infamous for imposing a deep freeze on whoever disagrees with him, discovers that in his advanced teenaged years his hands constantly feel chilled. as he is a cool physics student, the iceberg kid quickly calculates the resistance of the resistor needed to warm his hands. given that 161 j of thermal energy is generated by the resistor during 6.03 s of operation while connected to a 12.0 v battery, find the correct value of this resistance (and avoid a cold, cold fate).

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?
