a. b. c. d. 1.41 The diffusion coefficient of Sn in Cu at two temperatures is D = 1.69 × 10−9 cm2 hr−1 at 400 °C and D = 2.48 × 10−7 cm2 hr−1 at 650 °C. Calculate the rms distance diffused by an Sn atom into the copper, assuming the cooling process takes 10 seconds. What should be the composition of the solder if it is to begin freezing at 250 °C? What are the components (phases) in this alloy at 200 °C? What are the compositions of the phases and their relative weights in the alloy? What is the microstructure of this alloy at 25 °C? What are weight fractions of the α and β phases assuming near equilibrium cooling?

7 1 point A 8% coupon bond has a par value of $1,000 and a yield-to-maturity of 8%. You purchase the bond when it has exactly 15 years remaining until maturity. You hold the bond for 6 months, collect the coupon payment, and then sell the bond immediately. If the bond's yield-to-maturity is 5% when you sell it, what is your percentage return over this 6-month holding period? DO NOT annualize your answer. Enter your answer as a decimal and show 4 decimal places. For example, if

A block of mass $m = 2.50$ kg is pushed $d = 2.60$ m along a frictionless horizontal table by a constant applied force of magnitude $F = 11.0$ N directed at an angle \theta$= 25.0^\circ$ below the horizontal as shown in the figure below. (a).Determine the work done by the applied force. is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. J (b) Determine the work done by the normal force exerted by the table. J (c) Determine the work done by the force of gravity. J (d) Determine the work done by the net force on the block. J
