The image below shows a loop of wire passing through a magnetic field at constant speed. Which of the following statements best describes the current in the wire as the wire passes through the field?
Moving loop
A. The current remains constant and in the same direction as the wire loop moves across the magnetic field.
B. The current steadily increases as the loop approaches the midpoint directly above the magnet, and then decreases steadily as the loop continues.
C. The current decreases to zero as the loop approaches the midpoint, and then changes direction and increases as the loop continues past the midpoint.
D. There is no current in the loop as the loop crosses the magnetic field at a steady speed.

Sort the images based on whether there's a force of attraction or repulsion between the magnets shown. attraction repulsion

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
