Part B Determine the energy released per kilogram of fuel used. • Given MeV per reaction, calculate energy in joules per kilogram of reactants.
• Consider 1 mole of tritium plus 1 mole of deuterlum to be a mole of "reactions" (total molar mass = 5 grams). ​

A0.580-kg rock is tied to the end of a string and is swung in a circle with a radius of 0.500 meters. the velocity of the rock is 4.50 m/s. what is the centripetal force acting on the rock? 15.5 n 5.22 n 69.8 n 23.5 n

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?

What is the speed of an object at a given moment?
