The electric field at point p due to a point charge q a distance r away from p has magnitude e. in order to double the magnitude of the field at p, you could the electric field at point p due to a point charge q a distance r away from p has magnitude e. in order to double the magnitude of the field at p, you could double the charge to 2q and at the same time reduce the distance to r/2. reduce the distance to r/4. double the charge to 2q. reduce the distance to r/2. double the distance to 2r.

Chemical energy is a form of energy. a. heat b. kinetic c. potential d. electromagnetic

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?

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)
