- 4. The correct unit for a joule is a) 1kg-m/s b) 1kg-m^2/s^2 c) 1g-cm/s d) 1kg-cm^2/s^2
- Which statement best describes what occurs to create a lightning strike? Negative charges in the cloud attract negative charges in the ground. Ice particles bump into each other Excess electrons settle at the bottom of a storm cloud and polarize the ground Positive streamers leave the clouds and connect to loose electrons in the air
- Irregular galaxies are different than Spiral and Elliptical galaxies in that they do not have a distinct shape do not have an age do not have stars do not exist
- Two identical objects A and B of mass M move on a one-dimensional, horizontal air track. Object B initially moves to the right with speed V_(0) Object A initially moves to the right with speed 3v_(o) so that it collides with object B. Friction is negligible. Express your answers to the following in terms of M and v_(0) a. Determine the total momentum of the system of the two objects. b. A student predicts that the collision will be totally inelastic (the objects stick together on collision). Assuming this is true, determine the following for the two objects immediately after the collision. i. The speed ii. The direction of motion (left or right) When the experiment is performed the student is surprised to observe that the objects separate after the collision and that object B subsequently moves to the right with a speed 2.5v_(0) C. Determine the following for object A immediately after the collision. i. The speed ii. The direction of motion (left or right) d. Determine the loss of kinetic energy in the actual experiment. __
