Table 7.1 Energy of Various Objects and Obj Big Bang Energy released in a supernova Fusion of all the hydrogen in Earth's oceans 10 Annual world energy use Large fusion bomb (9 megaton) 1 kg hydrogen (fusion to helium) 1 kg uranium (nuclear fission) Hiroshima-size fission bomb (10 kiloton) 90,000-ton aircraft carrier at 30 knots 1 barrel crude oil Energy in joules 10 10 68 34 20 4x10 3.8x 10 6.4x10 8.0x 10 4.2x 1013 1.1x 1010 5.9x 10 4.2x 10 1.2x 10 14 13 1 ton TNT 1 gallon of gasoline Daily home electricity use (developed countries) 7x10 Daily adult food intake (recommended) 1000-kg car at 90 kmh 1 g fat (9.3 kcal) ATP hydrolysis reaction 1 g carbohydrate (4.1 kcal) 1 g protein (4.1 kcal) Tennis ball at 100 kmh 1.2x10 3.9x104 3.2x 104 1.7x104 1.7x104 Mosquito (102 g at 0.5 m/s) Single electron in a TV tube beam Energy to break one DNA strand 1.3x10-6 4.0x10- I0FExplanation / Answer
Here ,
single electron in a TV tube beam , ET = 4 *10^-15 J
energy to break one DNA strand , ED = 10^-19 J
Now ,
number of DNA molecules that can be broken = ET/ED
number of DNA molecules that can be broken = 4 *10^-15/(10^-19)
number of DNA molecules that can be broken = 4 *10^4
the number of DNA molecules that can be broken is 40000
