Problem 3 An asteroid closely passes the Earth at a range of 17200 mi and relative speed of 7.8 km/s. The diameter is estimated at 30 m with a specific gravity of 3. If this asteroid had impacted Earth, how much energy would have been released? Express this quantity in units of mega- tons (Mton) where a megaton is the energy released by one million metric tons of TNT explosive. A metric ton is 1000 kg and the explosive energy density of TNT is 4184 J/g. Hint: If the asteroid hits the Earth, its relative velocity becomes zero. Ignore any change in asteroid velocity due to gravitational acceleration or air resistance.

How does a nuclear reactor produce energy? O Atoms, such as uranium, undergo fusion in a reactor. This generates heat which turns water to steam in a turbine which generates electricity. Atoms, such as uranium, undergo fission in a reactor. This generates heat which turns water to steam in a turbine which generates electricity. O Atoms, such as uranium, burn in a reactor. This generates heat which turns water to steam in a turbine which generates electricity. O We do not currently have the technology to harness nuclear reactions to generate electricity.

U-235 sphere the size of a Tootsie Pop Assume that a spherical volume of pure U-235 is the size of a Tootsie Pop. The per capita electrical energy usage (i.e., per person per year) in the U.S. is 11,496 kw-hrs a) How many years would this amount of U-235 power the average person if all the U-235 atoms were fissioned? b) What would be the approximate volume of the waste produced, when the entire sample has fissioned? (Describe this qualitatively.) Assumptions to use: • Pop diameter = 1.25 inch • Density of the U-235 sample = 18.95 g/cc . The atomic mass is 235.044 amu • 180 MeV of heat energy are available from each fission . The efficiency for thermal to electric conversion is 0.32 . Avogadro's number = 6.022e23.
