5. Carbon-14 undergoes beta emission to form nitrogen-14. The half-life for this reaction is 5700 ± 30 yr. The 14C/12C ratio in living organisms is 1.3 × 10^−12, with a decay rate of 15 decays per minute/g of carbon. In 1990, the remains of an apparently prehistoric man were found in a melting glacier in the Italian Alps. Analysis of the 14C content of samples of wood from his tools gave a decay rate of 8.0 dpm/g carbon. How long ago did the man die?

Example 4.1.10. Let $X_1$ and $X_2$ be discrete random variables. Suppose the conditional pmf of $X_1$ given $X_2$ and the marginal distribution of $X_2$ are given by $p(x_1|x_2) = \binom{x_2}{x_1} (\frac{1}{2})^{x_1}$, $x_1 = 0, 1, \dots, x_2$ $p(x_2) = \frac{2}{3}(\frac{1}{3})^{x_2 - 1}$, $x_2 = 1, 2, 3, \dots$ Find the mgf of $X_1$.

c. We now place at B a point charge $q_2 = 6 \times 10^{-10} C$. 1- Calculate the electric force exerted by $q_1$ on $q_2$. 2- Is this force repulsive or attractive? Justify. Second Exercise (8 marks) A point charge $q_1 = 9nC$ is placed at the origin O. Another point charge $q_2 = 4nC$ is placed on the x-axis at point C (x = +20 cm). a. Calculate the electric fields $E_1$ and $E_2$ created respectively by $q_1$ and $q_2$ at point M of abscissa x = +7 cm.
