First, slowly move the magnet into the shorter coil of wire (the coil near the top). What happens to the voltage when the magnetic field lines that are closer together (at the North and South Poles) move through the wire, compared to when the middle of the magnet moves through the coil?

In november 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. the chunk of ice was estimated to be 98 mi long, 25 mi wide, and 750 ft thick. a typical backyard swimming pool contains about 24,000 gallons of water. how many of these pools could you fill from the water in this iceberg? (assume the iceberg is a rectangular solid of the above dimensions and consists of water only). express answer in scientific notation.
