A 12.0-V battery-operated bottle warmer heats 50.0 g of glass, 2.50 × 102 g of baby formula, and 2.00 × 102 g of aluminum from 20.0 °C to 90.0 °C . (a)How much charge is moved by the battery? (b) How many electrons per second flow if it takes 5.00 min to warm the formula? (Hint: Assume that the specific heat of baby formula is about the same as the specific heat of water.)
During a lightning flash, -6 C of charge is transferred across a potential difference of about10^7 V. The flash lasts approximately 1 ms. Calculate the average power during the flash –that is, the average rate of electrical energy decrease.
