At time t =0, the current to the dc motor is reversed, resulting in an angular displacement of the motor shaft given by è = (198 rad/s)t – (24 rad/s2)t2 – (2 rad/s3)t3 (15 marks) a. At what time is the angular velocity of the motor shaft zero? b. Calculate the...

There are two polarizing filters that are out of alignment by 30 degrees. If the light of intensity 1.00 W/m^2 and initially polarized half-way between the two filters passes through the two filters, what is the intensity of the transmitted light? I know the answer is 0.700 W/...
