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 181 j of thermal energy is generated by the resistor during 9.99 s of operation while connected to a 12.0 v battery, find the correct value of this resistance (and avoid a cold, cold fate).
