There is a uniform magnetic field of magnitude 2.1 T in the +z direction. Find the magnitude F1 of the force in a particke of charge -1.1 nC if its velocity is 2.0 km/s in the yz plane in a direction that makes an angle of 34 degrees witb the z axis. Find the magnitude F2 of the force on the same particle if its velocity is 2.0 km/s in the xy plane in a direction that makes an angle of 34 degrees with the x axis.

8. Let $\vec{F}(x, y) = (2xy + 3, x^2 - 3y^2)$. a. Determine whether $\vec{F}$ is conservative. Show all work that leads to your conclusion. b. If $\vec{F}$ is conservative, find a potential function and use it along with the Fundamental Theorem for Line Integrals to evaluate $\int_C \vec{F} \cdot d\vec{r}$, where C is the curve given by $\vec{r}(t) = (t^2 \sin t, 2 - t^2 \cos(\frac{t}{2} - \frac{2t}{\pi}))$, $0 \le t \le \pi$. If $\vec{F}$ is not conservative, evaluate the line integral directly.

The formic acid produced by oxidation of formaldehyde. However, under the reaction conditions some undesirable reactions take place to produce CO$_2$, H$_2$, CO and H$_2$O. The reactions that occur are: CO$_2$ + H$_2$ k$_2$ k$_1$ HCHO + 1/2 O$_2$ HCOOH k$_3$ CO + H$_2$O The reaction rate for oxidation of formaldehyde reaction is first order for formaldehyde and zero order for oxygen. These reactions are carried out in a batch reactor in which feed contains 67% HCHO and 33% O$_2$. The reaction rate constants $k_1$, $k_2$ and $k_3$ are 0.001 s$^{-1}$, 0.003 s$^{-1}$ and 0.002 s$^{-1}$, respectively. a) Derive an equation for concentration of HCHO as a function of time and calculate the ratio $C_{HCHO}$/$C_{HCHO,0}$ after 3 min. b) Derive an equation for concentration of HCOOH as a function of time and calculate the concentration of HCOOH after 4 min if $C_{HCHO}$ equals to 0.15 mol/dm$^3$ and $C_{O_2,0}$ equals to 0.07 mol/dm$^3$. c) Sketch the concentrations as functions of time. What time gives the maximum concentration of HCOOH? d) If the series reaction is carried out in a CSTR, determine the reactor volume that will maximize the production of HCOOH for a volumetric flow rate of 15 dm$^3$/min. NOTE: Use numerical method (Classical RK-4) for your solutions.

The prime rate is the interest rate at which banks can borrow from the Fed. False would be an excess supply of money. A decrease in the money supply will tend to reduce investment. When people expect inflation, they assume that prices are going to increase at a certain rate and factor this into their decision making. To increase the level of output, the Fed should conduct an open market sale. The outside lags related to monetary policy tend to be quite long. 12)+ If the actual interest rate in the money market is higher than the equilibrium interest rate, there 13)+ If your assets are highly liquid, this means you can make transactions on short notice. 17)+ Spending on consumer durables decreases as the interest rate increases. 18)+ If the Federal Reserve raises the discount rate, banks will be inclined to borrow additional 19)+ reserves and the money supply will increase. When the public expects inflation, real and nominal interest rates will differ because inflation needs to be accounted for in calculating the real return from lending and borrowing. When the Fed conducts an open market sale, it leads to a higher level of investment and output in the economy. An increase in the money supply will appreciate a country's currency. When the Federal Reserve decreases the money supply, it generally does so by purchasing bonds. When the public expects inflation, real and nominal rates of interest will be the same.
