What happens when a current moves through a wire and the wire is placed near a magnet? a. it creates friction which interacts with the magnetic field of the magnet and it causes the wire to move. b. it creates friction which interacts with the magnetic field of the magnet and it causes the wire to stay still. c. it creates a magnetic field which interacts with the magnetic field of the magnet and it causes the wire to change temperature. d. it creates a magnetic field which interacts with the magnetic field of the magnet and it causes the wire to move.

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i. e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i. e. include the distance traveled to the first encounter)

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.

Properties seen when one one substance changes to another are known as properties
