Two asteroids collide while traveling at constant velocities. Ignoring their gravitational attraction to each other, the forces between them act: 1.) Only before the collision.

2.) Only during the collision.

3.) Only after the collision.

4.) Before, during, and after the collision.

Three resistors are connected in series across a 15-v power supply. if the potential drops across resistors 1 and 2 are 4.1 volts and 3.1 volts, what is the exact potential drop (in volts) across resistor 3?

Two positive charges are equal. which has more electric potential energy?

Which statement is true about an object that is moving in a circular motion due to centripetal force, f, when the radius of its circular motion is doubled? the new force then becomes equal to 2f the new force then becomes equal to f the new force then becomes equal to f/2 the new force then becomes equal to f2 the new force then becomes equal to 1/f
