Given that the average number of fast neutrons emitted following the thermal-neutron induced fission of 235U is 2.42 per fission event; use the following data to calculate the mean number of fission neutrons produced per initial thermal neutron in a large volume sample of (a) pure 235U (b) natural uranium 238U, and (c) uranium enriched to 3% in the 235U isotope. Note: The microscopic absorption cross section for 235U is 694 barns. The cross section for 238U is 2.71 barns....

1.Which statement is true about nuclear fission or bombs? A moderator slows down neutrons to make fission less likely. The nuclear bomb dropped on Hiroshima in WWII was called Fat Man. A moderator slows down neutrons to make fission more likely. The nuclear bomb in WWII that used 235U and a gun-type design was called Fat Man. The maximum amount of fissile material that will sustain a chain reaction is called the critical mass. Tries 0/2 The correct ranking of...

Suppose you have a system of two masses strung over a pulley. Mass 1 (6.2 kg) hangs on the right side of the pulley suspended over the ground at height 0.7 m. Mass 2 (2.3 kg) hangs over the left side of the pulley and rests on the ground. The pulley is a uniform disk of mass m and radius 12.5 cm. When the system is released, Mass 1 moves down and Mass 2 moves up, such that Mass 1...

Suppose you have a system of two masses strung over a pulley. Mass 1 (6.7 kg) hangs on the right side of the pulley suspended over the ground at height 1.2 m. Mass 2 (2.5 kg) hangs over the left side of the pulley and rests on the ground. The pulley is a uniform disk of mass m and radius 11.3 cm. When the system is released, Mass 1 moves down and Mass 2 moves up, such that Mass 1...

1. All train cars in this problem are identical and have masses of 45,000 kg each. Three cars, coupled together, are rolling east at 2.4 m/s. A fourth car, traveling west at 3.4 m/s collides with the three and couples to make a four car unit. A moment later, the train cars contact a car that was at rest on the tracks, and it couples to make a five car train. a) What is the speed of the five car...

Analysis of an explosion 1. suppose that 2 carts have equal masses, m and that they both have velcro bumpers. Suppose that one of the carts will have a spring that can be compressed, thus mechanical energy stored (can be converted in kinetic). Then, you compress the spring and place both carts at the middle of the track. suppose that you release the spring. a) is the collision elastic? b) what is the total kinetic energy of the system before...

1.Three identical very dense masses of 3500 kg each are placed on the x axis. One mass is at x1 = -120 cm , one is at the origin, and one is at x2 = 300 cm . What is the magnitude of the net gravitational force Fgrav on the mass at the origin due to the other two masses? Take the gravitational constant to be G = 6.67×10−11 N⋅m2/kg2 . Express your answer in newtons to three significant figures....
