You are measuring the pressure with a sensor embedded in a bridge. The bandwidth of the sensor is only 30 Hz, which means it can only measure changes less than 30 times a second. However, there is a 60 Hz high power power line nearby that might affect the signal acquisition. To reduce the induced noise to minimum, which type of filter should be used?Design a filter that can filter out all the noises with a 10 kΩ resister.

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
