7. (10%) Resistors of 10 and 30 ohms are connected in parallel. What is the resistance of thisnetwork?

48. What is the status of the C and Z flags after the following code? to sin LDAA #$FF ADDA #1

25. Explain the difference between Prandl layer and Ekman layer: (2%)

9. (10%) If a homeowner with an R 4.0 house paid $350/month for his natural gas bill and the house next door had an R 14.0 house of the same area, what would you expect for the natural gas bill for the R 14.0 house?

32. Identify the addressing mode for each of the following: (a) STAA PORTB (b) LDAA #$50 (c) STAA $800 (d) LDAA #0 (e) CLRA (f) ABA

8. (10%) Heat flow is given by the equation Q/t = A x AT/R, where the heat flow per time is Q/t, the thermal resistance is R, the area is A. The difference in temperature on the two sides of the wall is AT in degrees Celsius. If A and AT are constant, and the R value is improved from 4.0 to 14.0, what is the relative heat flow as a percentage in the R 14.0 wall compared with the R 4.0 wall?

55. Of C and Assembly language, which is more efficient in terms of code generation (i.e., the amount of ROM space it uses)?
