Consider the uniform electric field E = 650 V/m or N/C (pointing upward) produced by a parallel plate capacitor as shown in the figure below. The separation distance between plates 1 and 2 is 12.0 cm. A. The plate A is [Select] and the plate 2 is [Select] B. The given E-field in the unit vector notation can be expressed as [Select] below). Choice I) $\hat{0}_i + 650 \hat{0}_j$ N/C Choice II) $650 \hat{0}_i + 0 \hat{0}_j$ N/C Choice III) $\hat{0}_i - 650 \hat{0}_j$ N/C Choice IV) $-650 \hat{0}_i + 0 \hat{0}_j$ N/C Choice V) $650 \hat{0}_i + 650 \hat{0}_j$ N/C C. If a charge with +3.5µC is placed in the middle of the two plates in electrostatic equilibrium, then the electrostatic force on this charge particle will be [Select] mN (milliNewtons) pointing [Select]

Consider first order wave equation $\frac{\partial u}{\partial t} + c \frac{\partial u}{\partial x} = 0$ The Lax-Wendroff scheme for this wave equation is given as: Derive the associated modified equation is: $\frac{\partial u}{\partial t} + a \frac{\partial u}{\partial x} = -\frac{a(\Delta x)^2}{6}(1 - v^2)\frac{\partial^3 u}{\partial x^3} - \frac{a(\Delta x)^3}{8}v(1 - v^2)\frac{\partial^4 u}{\partial x^4} + ...$ and verify that the scheme is conditionally stable for $v \leq 1.$

Greenleaf Manufacturers, Inc. projected sales of 70,000 machines for 2012. The estimated January 1, 2012, inventory is 7,000 units, and the desired December 31, 2012, inventory is 12,000 units. What is the budgeted production (in units) for 2012? Magnolia, Inc. manufactures bedding sets. The budgeted production is for 55,000 comforters in 2012. Each comforter requires 7 yards of material. The estimated January 1, 2012, beginning inventory is 31,000 yards. The desired ending balance is 30,000 yards of material. If the material costs $4.00 per yard, determine the materials budget for 2012. Sweet Dreams, Inc. manufactures bedding sets. The budgeted production is for 52,000 comforters in 2012. Each comforter requires 1.5 hours to cut and sew the material. If cutting and ewing labor costs $11.00 per hour, determine the direct labor budget for 2012.
