Coding problems: HW4_3: The following system of equations is designed to determine concentrations (in gm/m³) in a series of coupled reactors as a function of the amount of mass input to each reactor (in g/day): $$15c_1 - 3c_2 - c_3 = 3800$$ $$-3c_1 + 18c_2 - 6c_3 = 1200$$ $$-4c_1 - c_2 + 12c_3 = 2350$$ Write a PYTHON code to solve this problem using Gauss-Seidel method correct to 3 significant figures. Display the final answers using formatted printing.
The S.I. unit used in expressing magnetic field strength is the __________.
How do I solve this? Please show all steps and answer all questions. The effective neutron multiplication factor, k, for any nuclear system is defined as: number neutrons in current generation k= number neutrons in last generation In a fast reactor, the mean neutron lifetime is dominated by the delayed neutrons, because the fission neutrons undergo minimal down-scattering before they are absorbed. The mean lifetime of delayed neutrons is 12 ms and the delayed neutron fraction if 0.0065 1.1 a[5pts] Calculate the mean neutron lifetime of a fast reactor 1.2 b[10pts] Suppose a fast reactor has a power of 10 MW.If k = 1.0000003 how long does it take the reactor power to increase to 20 MW? 1.3 c [10pts] Suppose the hydraulics that move the control rods have a response time of 100 ms. What is the maximum k the reactor should ever be operated at such that the power does not more than double before the control rods move Useful values Nuclide Mass [amu] n 1.0086648 1H 1.0078250 2H 2.0141017 3H 3.0160491 3He 3.0160292 4He 4.0026032 Table 1.1 Some important fusion reactions and parameters of the cross-section factoriza tion 1.21.

Question Solve $u_{xx} + u_{yy} = 0$, $0 < x < a$, $0 < y < b$ $u(0, y) = 1$, $u(a, y) = 0$ $u(x, 0) = 0$, $u(x, b) = 0$
2-5 Suppose that $Y_1, Y_2, \dots, Y_n$ are random variables with a common mean $\mu_Y$; a common variance $\sigma_Y^2$; and the same correlation $\rho$ (so that the correlation between $Y_i$ and $Y_j$ is equal to $\rho$ for all pairs i and j where $i \neq j$)\\ a) Show that $cov(Y_i, Y_j) = \rho \sigma_Y^2$ for $i \neq j$\\ b) Suppose that $n=2$ show that $E(\bar{Y}) = \mu_Y$ and $var(\bar{Y}) = \frac{1}{2}\sigma_Y^2 + \frac{1}{2}\rho\sigma_Y^2$.
