The starter motor of a car engine draws an electric current of 146 A from the battery. The diameter of the copper wire is 6.00 mm and the wire is 1.42 m long. The starter motor runs for 0.45 s before the car engine starts up. How much electric charge passes through the starter motor

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
