A model depicts two balloons of the same size with identical negative charges being moved toward one another at the same speed. How will the balloons interact with each other? A.) They will repel, moving in opposite directions at the same speed.

B.) They will repel, moving in the same direction at different speeds.

C.) They will attract, moving in the same direction at the same speed.

D.) They will attract, moving in opposite directions at different speeds.

The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e

What is required for an electric charge to flow through a wire? zero resistance in the wire a balance of electric potential high resistance in the wire a difference in electric potential

Cells in the nervous system have a potential difference of 70 mv across the cell membrane separating the interior of the cell from the extracellular fluid. this potential difference is maintained by ion pumps that move charged ions across the membrane. is this an emf? select the correct answer and explanation. 1)no. the ion pumps cannot separate charges; thus, they cannot create a potential difference. 2)yes. the ion pumps cannot separate charges, but they still can create a potential difference. 3)yes. the ion pumps can actively separate charge; thus, they can create a potential difference. 4)no. the ion pumps can separate charges, but they cannot create a potential difference.
