Two neutral species, A and B, with diameters 655 pm and 1820 pm, respectively, undergo the diffusion-controlled reaction A + B → P in a solvent of viscosity 2.93×10-3 kg m-1 s -1 at 40 ℃. Use eqn 15B.3 to calculate the initial rate d[P]/dt, given that the initial concentrations of A and B are 0.170 mol dm-3 and 0.350 mol dm-3 , respectively. Then repeat the calculation by using eqn 15B.4. Comment on the validity of the approximation that leads to eqn 15B.4.

At a corner of the table, place a piece a coin or another small object. Hold a ruler behind it and a piece of chalk or another coin on the end of the ruler, over the edge of the table. Give the ruler a sharp tap. The coin B on the ruler, left behind by its inertia, falls vertically. The coin A on the table has a horizontal velocity. Record your observations about when the coins hit the ground (listening may be easier than seeing.) Alternate: This experiment can be done without the ruler by getting one coin to nudge the other off the table.

Q8. (10 marks) Using Euler's method with a step size of h = 0.1, find the value of X(1.3) for the initial-value problem dx/dt = z(1) = 2F + JP. Note that the calculations incurred in this Question 8 must be with at least five decimal place accuracy. Q9. (10 marks) Find the general solution of the following differential equation: f''(t) + 4x = 3t + 2 Q10.* (10 marks) Figure 1 below depicts an RLC circuit in which R, L, and C are in series. The RLC circuit is with R = 22Î©, L = 0.2H, C = 0.005F. Moreover, denote by i(t) the current inside the circuit. The circuit is connected to a source of voltage E(t) = 200sin(400t). The RLC circuit in Figure 1 is modeled by the following ODE: di(t)/dt + R/L * i(t) + 1/(LC) * âˆ«i(t)dt = E(t) Find the current i(t) in the RLC circuit. Assume that the initial conditions are zero, i.e., i(0) = 0 and d/dt(i(0)) = 0.
