1. Calculate the total binding energy of Be nucleus assuming that it's mass - 8.00531 u. (Atomic mass unit: 1 u = 1.66053886 107 kg, and 22 - 931.494013 Mevlu). 2. Assuming that a single proton is a sphere of radius 1 fm and two protons are fired at each other with the same kinetic energy E, calculate (a) the final Ein these particles are brought to rest by their mutual Coulomb repulsion when they are just touching each other? Taking this value of as a representative measure of the height of the Coulomb barrier, calculate (b) the temperature of a gas of protons that have this average kinetic energy and thus have equal to the height of the Coulomb barrier? by - 1.38 10-20 J/K. 3. The ratio of 2350 to 200 in natural uranium deposits today is 0.0072. What was this ratio 2 billion years ago if known that the half-life of the two isotopes is 7.04 10 years and 4.47 10 years, respectively?
