Consider two points in an electric field. The potential at point 1, VI, is 23 V. The potential at point 2, ½, is 154 V. An electron at rest at point 1 is accelerated by the electric field to point 2. 25% Part (a) Write an equation for the change of electric potential energy ?? of the electron in terms of the symbols given.

Lets say that an object of a certain volume has a certin mass. what happens to its mass when you double its volume?

In a stagnant pool of water, a crayfish may spend much of its time lying with one side of its carapace near the surface of the water. in this position, it will move the walking legs on that side in a rhythmic back-and-forth motion. explain the likely function of this behavior.

When you jump from an elevated position you usually bend your knees upon reaching the ground. by doing this, you make the time of the impact about 10 times as great as for a stiff-legged landing. in this way the average force your body experiences is a) less than 1/10 as great. b) more than 1/10 as great. c) about 1/10 as great.d) about 10 times as great.
