Nuclear fusion, like the example here, produces huge amounts of energy. consider the statements below. all but one statement provides more information about nuclear fusion. a) nuclear fusion is the source of energy in our sun. b) nuclear fusion begins when a large, unstable nucleus is bombarded with a smaller particle. c) nuclear fusion is responsible for the formation of the elements we classify in the periodic table. d) nuclear fusion when used as an energy source does not produce particulate matter pollution like fossil fuel combustion.

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
