Ideal Gas Law: As shown in the figure, an air pocket at the top of a vertical tube, closed at the upper end and open at the lower, occupies a volume of 560 cm3 at the surface of a lake where the air pressure is 1.0 × 105 Pa and the temperature is 37°C. What is the volume of the air in the pocket if the tube is taken to a depth of 56 meters, where the temperature is 7°C? Assume that none of the air escapes from the tube. The density of the water in the lake is 1000 kg/m3.
Fill in the blank(s) with the appropriate word(s).

A rectangular coil of 100 turns measures 40.0 cm by 20.0 cm. This coil is placed next to an electromagnet which is switched on, increasing the magnetic field through the coil from zero to 0.800 T in 50.0 ms. If the resistance of the coil is 2.0 ohms, what are the induced voltage and current in the coil?
