Find the y, g, and h parameters. The second set of measurements gives V=30/0V, I=1.530A. V=0V, I=0.250A. Therefore, Vi = 30/0, 120/30, 1V = 0, 0.25/150, 11 - 1.5/30 = 6/60, 12V = 0, 0.25/150. a12 a21 The following measurements were made on a two-port resistive circuit. With 50mV applied to port 1 and port 2 open, the current into port 1 is 5A, and the voltage across port 2 is 200mV. With port 1 short-circuited and 10mV applied to port 2, the current into port 1 is 2A, and the current into port 2 is 0.5A. Find the g parameters of the network.

GM's pension fund has liabilities worth $100 billion today and with a duration of 14 years. Suppose for simplicity that the value of its assets is also $100 billion today. The interest rate is 5% at all maturities. Suppose the fund's assets can only be 10-year or 30-year zero coupon bonds. If the fund wants to minimize its exposure to interest rate risk, it should have % (answer an integer, e.g. 13) of its assets in 10-year zero-coupon bonds.
