Tot The following report for a collision of two marbles has an error. "Marble 1 has a mass of 12 g, an initial speed of 0.84 m/s left, and a final speed of 0.21 m/s right. Marble 2 has a mass of 23 9, an initial speed of 0.42 m/s right, and a final speed of 0.31 m/s left. What change to the report's data would give a correct verification of momentum conservation?

Suppose a wire with a current is pushed upward by a magnetic field. how would the wire move if the direction of the current reversed? explain your answer.

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
