Do the two cars ever have the same velocity at one instant of time? if so, between which two frames? check all that apply. check all that apply. cars have the same velocity at one instant of time between dots 1 and 2. cars have the same velocity at one instant of time between dots 2 and 3. cars have the same velocity at one instant of time between dots 3 and 4. cars have the same velocity at one instant of time between dots 4 and 5. cars have the same velocity at one instant of time between dots 5 and 6. cars never have the same velocity at one instant of time.

How is the gravitational force related to the distance between two objects?

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.

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
