A long, straight wire carrying a current of 3.45 A moves with a constant speed v to the right. A 5-turn circular coil of diameter 1.25 cm, and resistance of 3.25 µΩ, lies stationary in the same plane as the straight wire. At some initial time, the wire is at a distance d = 20.0 cm from the center of the coil. 4.70 s later, the wire is at a distance 2d from the center of the coil. What is the magnitude and direction of the average induced current in the coil? Note that while the magnetic field varies over the diameter of the coil, it is very small and we will disregard this variation.

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.

Which compound is held together by the electrostatic force between two ions? a. co2 b. cci4 c. h2s d. mgf2
