A 150 g copper bowl contains 180 g of water, both at 20.0°C. A very hot 470 g copper cylinder is dropped into the water,
causing the water to boil, with 17.5 g being converted to steam. The final temperature of the system is 100°C. Neglect
energy transfers with the environment. (a) How much energy is transferred to the water as heat? (b) How much to the
bowl? (c) What is the original temperature of the cylinder? The specific heat of water is 1 cal/g. k, and of copper is 0.0923
cal/g. K. The latent heat of vaporization of water is 539 Cal/kg.

To create electromagnetic induction, which of the following has to move? a. a wire b. a magnet c. a transformer d. either a or b

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
