The ends of a massless rope are attached to two stationary objects (e. g., two trees or two cars) so that the rope makes a straight line. For this situation, which of the following statements are true? Check all that apply. 1. The tension in the rope is everywhere the same. 2. The magnitudes of the forces exerted on the two objects by the rope are the same.3. The forces exerted on the two objects by the rope must be in opposite directions.4. The forces exerted on the two objects by the rope must be in the direction of the rope.

An alpha particle with kinetic energy 12.5 mev makes a collision with lead nucleus, but it is not "aimed" at the center of the lead nucleus, and has an initial nonzero angular momentum (with respect to the stationary lead nucleus) of magnitude l = p0 b, where p0 is the magnitude of the initial momentum of the alpha particle and b=1.40×10−12 m. (assume that the lead nucleus remains stationary and that it may be treated as a point charge. the atomic number of lead is 82. the alpha particle is a helium nucleus, with atomic number 2.) what is the distance of closest approach?
