(50 marks) Question 1. Consider the circuit shown below. Va Ra Vo Vb Rb Vc Rc Figure 1: Circuit used in questions 1 and 2. a) (30 marks) Suppose $V_b = V_c = 0$. Find the voltage, at the output and how it depends on $V_a$. Note: the more you simplify your answer, the easier it will be to find the next answer. b) (10 marks) Using super position, show that $V_o$ can be understood as some sort of average of $V_a$, $V_b$, and $V_c$. c) (10 marks) What determines which one of the three input voltages has a bigger contribution to $V_o$?

18. There are several autosomal recessive mutations associated with the development of estrogen-responsive cancers such as breast cancer and ovarian cancers. However, these mutations have varying penetrance. For example, mutations in BRCA2 have about a 48\% penetrance in the development of breast cancer by age 80. These mutations, however, are usually dominant in nature. A woman is diagnosed with breast cancer and after genetic testing, her oncologist determines it is a BRCA2 positive cancer. What is the probability that her daughter will develop breast cancer by age 80?

In cats, a particular locus causes white or black fur. The S allele causes white spotting and is codominant with the s allele which causes black spotting. A researcher goes out and measures coat color of the population and finds that 9% of the population are full white and 51% of the population is full black. The remaining part of the population has black and white spots. Based on the genotypic frequencies, is the population in Hardy-Weinberg equilibrium.

3. A turbine that uses steam drives an electric generator. The inlet steam flows through a 10-cm diameter pipe to the turbine at the rate of 1.5 kg/s at 550°C and 1000kPa. The exit stream discharges through a 25-cm diameter pipe at 400°C and 100kPa; at a point 5m below the turbine inlet. Heat loss from the turbine is estimated to be $10^3$ kcal/h. a. Draw a flowchart for the process b. What is the shaft work delivered by the turbine in kW? c. Would the shaft work be higher or lower if the process was adiabatic? By how much? (40 marks)
