The atomic bomb that was dropped on Nagasaki in 1945 killed 140,000 people, helping to end World War II on the next day. It released energy equivalent to that of 20,000 tons of TNT explosive
How much mass was converted to energy when this took place? (1000 tons of TNT = 4.3 × 1012 J) Incidentally, modern H-bombs have energy yields 1000 times as much! A)
1 g
B)
10 g
C)
100 g
D)
1 kg
E)

Why will a smaller body (the Moon, for example) cool much faster than a larger body like Earth?
A. A smaller body will have a smaller iron core, which holds heat better than rock. B. A smaller body has a larger surface area for heat to escape through, relative to its volume. C. A smaller body will have a smaller proportion of radioactive elements. D. A smaller body is less likely to have an atmosphere than a larger body.
Earth and Venus both presumably had similar gases outgassed from their volcanoes. Briefly explain how their atmospheres ended up so different
