The period of a pendulum is the time it takes the pendulum to swing back and forth once. If the only dimensional quantities that the period depends on are the acceleration of gravity, g, and the length of the pendulum, L, what combination of g and L must the period be proportional to? Acceleration has dimensions of [L][T−2]. g/L gL gL gL2 L/g

Consider the circuit shown below of a common source amplifier with a current mirror bias. Find the following: a. Find kp and kn. b. Find the drain current of M2 given that Ibias = 2mA and Vout = 2.5V. C. Find the gm and ro, of transistor M1. d. Sketch the small signal model of transistor M3 (Hint: Is there any small signal in any terminal of M3? If yes, then where is it? If no, then what happens to the small signal model?). It is given that the NMOS (M1) parameters are uoCox = 3 mA/V2, VTH,n = 0.5V and lambda = 0.02 and the PMOS (M2 and M3) parameters are uoCox = 1 mA/V2 and VTH,p = -0.6V . The PMOS transistor M3 does not have channel length modulation while PMOS transistor M2 has lambda = 0.02. It is also given that the dimensions of M2 and M3 have equal widths of 5 um and lengths of L2 = 3um and L3 = 1.5um, respectively. M1 has length of L1 = 1um and width of W1 = 2um.

A 65 kg girl is coasting back and forth on a swing as shown in the figure to the right. The ropes holding up the swing have length L and are very light but the seat of the swing is 5 kg. The girl is swinging back and forth such that it takes her 1.2 seconds to go from the backmost part of her swing (position A) to the frontmost part of her swing (position C). In this time she travels a total distance of 3 meters. 1) a) What is the length L of each rope of the swing? b) Some time later, the girl lets go of the swing at point C and the swing continues to oscillate back and forth without the girl. What is the period, T, of the swing after the girl lets go?
