A 14.0 V battery-operated bottle warmer heats 60.0 g of glass, 2.00 ? 102 g of baby formula, and 2.50 ? 102 g of aluminum from 25.0°C to 95.0°C. (Hint: Assume that the specific heat of baby formula is about the same as the specific heat of water. (a) How much charge (in C) is moved by the battery? C
(b) How many electrons per second flow if it takes 4.00 min to warm the formula? electron(s)

What are similarities and differences of reflection, refraction, diffraction and absorption?

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy

The temperature in gavin's oven is a sinusoidal function of time. gavin sets his oven so that it has a maximum temperature of 280°f and a minimum temperature of 240°. once the temperature hits 280°, it takes 20 minutes before it is 280° again. gavin's cake needs to be in the oven for 30 minutes at temperatures at or above 270°. he puts the cake into the oven when it is at 260° and rising. how long will gavin need to leave the cake in the oven? (round your answer to the nearest minute.)
