1) Maxwell the dog is trying to catch the cat, Shadow, using induction. He glues a strong magnet to Shadow’s collar, then puts a coil of wires consisting of 100 turns each with an area of 0.2m^2 next to some cat food. When Shadow walks through the coil, a current is induced in the loops which triggers a switch to drop a cage on Shadow. A minimum current of 0.2A is needed to spring the trap. The coils have a resistance of 120ohms. If the change in magnetic field is 0.3T in 0.2s as shadow walks through the coils, does the trap spring? If not, what can Maxwell do to fix his design? 2) Next Maxwell is trying to build an AC circuit to send a signal to a shock collar he put on Shadow while Shadow was sleeping. He has a 110Vrms source with variable frequencies. The circuit uses a 3mH inductor and 0.4mF capacitor. What frequency setting on the power supply will give the biggest power output of the circuit? Maxwell uses this frequency to drive the circuit, but misreads

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
