We want to get an idea of the actual mass of 235U involved in powering a nuclear power plant. A 1,000 MW electric power plant has a thermal power of approximately 3,000 MW. a. What rate of fission reactions is required to produce this power

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
