The energy yield of a nuclear weapon is often defined in terms of the equivalent mass of a conventional explosive. 1 ton of a conventional explosive releases 4.2 GJ. A typical nuclear warhead releases 250,000 times more, so the yield is expressed as 250 kilotons. That is a staggering explosion, but the asteroid impact that wiped out the dinosaurs was significantly greater. Assume that the asteroid was a sphere 10 km in diameter, with a density of 2500 kg/m3 and moving at 30 km/s. What energy was released at impact, in joules and in kilotons?
It is estimated that the total explosive yield of all the nuclear bombs in existence currently is about 4,000 MT.
(a) Convert this amount of energy to kilowatt-hours, noting that 1 kW ⋅ h = 3.60×106J .
(b) What would the monetary value of this energy be if it could be converted to electricity costing 10 cents per kW·h?
When a star has exhausted its hydrogen fuel, it may fuse other nuclear fuels. At temperatures above 1.0 x 10° K, helium fusion can occur. Write the equation for the following processes.
(a) Two alpha particles fuse to produce a nucleus A and a gamma ray. What is nucleus A? (Enter the mass number in the first raised box, the atomic number in the second lower box, and the
element, with charge if necessary, in the third box.)
(b) Nucleus A absorbs an alpha particle to produce a nucleus "B" and a gamma ray. What is nucleus B? (Enter your answer using the same format as above.)
(c) Find the total energy (Q) released in the reactions given in parts (a) and (b). Note: the mass of 4
= 8.005 305u.
