Water at room temperature and pressure flows steadily through the bend in the constant area channel shown below. As a result of the bend, the velocity profile changes from the uniform profile shown at location A to a profile at location B that is linear with a maximum velocity of $V_B$. Circle the correct statement. A. The velocity $V_A$ at location A equals $V_B/2$ B. The velocity $V_A$ at location A equals $2V_B$ C. The velocity $V_A$ at location A equals $1.5V_B$ D. The velocity $V_A$ at location A equals $V_B$ Location B Location A Velocity = $V_A$ Maximum velocity = $V_B$

What capacitance change will cause the 3 m/sec² acceleration in two different capacitive accelerometers: a) a parallel plate accelerometer b) a comb-drive accelerometer? Both accelerometers have the spring constant k=1 N/m, the proof mass m=0.1 mg. a) For the parallel plate accelerometer: the electrode plates is (100 ?m x 20 ?m), separation between electrodes is 2 ?m, k=1N/m Movable electrode m=0.1 mg Fixed electrode b) For the comb-drive accelerometer: A comb-drive accelerometer has hundred interdigitated fingers. The fingers are built from 3 ?m thick polysilicon d=2µm Fixed ? w=5µm I=100?m Movable
