A three-phase, 5-hp, 220V, six-pole, 60Hz induction motor runsat a slip of 0.025 at full load. Rotational and stray-lossesat full load are 5% of the output power. Calculate the power transferred across the air gap, the rotor copper loss at full load,and the electromagnetic torque at full nload innewton-meters.
a 50 kHz squarewave is input to the 60 kHz low pass filter. The filter is effective at rejecting frequencies higher than 60 kHz. a. Does it make sense that the output of the filter is a 50 kHz sinewave

Adding dopants to a sample of silicon is found to reduce the Hall coefficient by a factor of 10 and increase the conductivity by a factor of 5. What effect has this dopant addition had on the mean free path
Suppose you are designing a power amplifier for a loudspeaker which has an equivalent resistance of 150 . What should be the Thevenin equivalent resistance of the power amplifier in order to maximize the power transfer to the loudspeaker
a) Determine if the following expression is valid by using a truth table and by using algebraic manipulation: X1X3' + X2X3 + X2'X3' = ( X1 + X2' +X3)(X1 + X2 + X3')(X1' + X2 + X3) b) Use algebraic manipulation to show if x'(y' + z') = x'y' +x'z'
