Please explain your answer. The total momentum for any system of objects is constant so long as the following is true. (Select all that apply.)O so long as no unbalanced (or net) external forces act on the objects in the systemO so long as only conservative forces act between the objects in the systemThe total momentum for any system of objects is always constantKinetic energy for any system of objects is constant so long as the following is true. (Select all that apply.)O so long as no unbalanced (or net) external forces act on the objects in the systemso long as only conservative forces act between the objects in the systemThe total momentum for any system of objects is always constant.Using ratios to study collisionsAs long as a system of objects begins with non-zero momentum, we can use the ratio of the magnitude of the total momentum after the collision to themagnitude of the total momentum before the collision,to show the degree to which momentum was conserved during the collision.For example, consider a collision between a stationary cart and a moving cart on a low friction surface. We would expect the ratio p/p, to be which ofthe following?O equal to 1much greater than 1O much less than 1equal to 0Considering a collision where only conservative forces act between objects in the system, we'd expect that the ratio of KE/KE, would be equal to whichof the following?equal to 1much greater than 1much less than 1O equal to 0When considering the momentum of objects moving on a horizontal surface, we can ignore the effects of the vertical forces, such as the force of earth'sgravity and the force of the surface, because of which of the following?They do not sum to an unbalanced force.They are external to the system.They are conservative forces.They are too small to affect the motion.
