Learning Goal: To practice Problem-Solving Strategy 30.1 Electromagnetic Induction. A coil of wire contains N turns and has an electrical resistance R. The radius of each turn is a. The coil is short-circuited. Initially, inside the coil there exists a uniform magnetic field of magnitude B0 parallel to the axis of the coil. The magnetic field is then reduced slowly. The current induced in the coil is I. How long does it take for the magnitude of the uniform field to drop to zero?

Suppose while hauling rocks, you accidentally drop one. it breaks apart in flat, planar sections. what type of rock did you just drop? 20 points

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.

In an experiment, how can i change human errors? be specific.
