In a uranium fission reaction, uranium splits into two smaller atoms and energy. where did the energy come from? a. chemical bonds are broken, and chemical energy is released. b. when the uranium splits, mass and energy are created making the two new atoms. c. some of uranium's mass is converted into energy, so the smaller atoms have less mass. d. the energy had to be the kinetic energy of the atom of uranium before it split. i know its not b or a because i got them ; -; ! i'm thinking its d

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.

If you visited mount shasta city (elevation 900 m [3000 ft.]) and found the outside air temperature to be 27°c (81°f), what would be the air temperature at the summit of mount shasta (elevation 4200 m [14,000 ft.]) at that moment-assuming that the temperature conditions with altitude change at an average, or normal, lapse rate?
