Compute the power of the water exiting the penstock.

  Determine what is the no load speed of a shunt motor

A shunt motor with an armature resistance of 0.15ohms is running 1200rpm for a load which requires an armature current of 50A from 230V source. At no load, the armature current of 5A.

  What are the 2nd- and 3rd-order harmonics

A recording trace r(t) is definedas r(t) = s(t) + n(t), where s(t) =10sin(20?t) (i.e., a 10 Hz sine wave, given f= 2f) is the signal and n(t) = sin(120t) (i.e., the 60 Hz electromagnetic noise) the noise.

  Calculate the probability that the magnitude of the voltage

(b) This voltage is measured using a defective voltmeter, which always indicates a lower reading than the actual value. Suppose the voltmeter reading is 2.5*10^(-4). Calculate the probability that the error is not more than 0.5 *10^(-4).

  What effect would the signal source impedance

What effect would the signal source impedance have on the non-inverting amplifier?

  What is the readout error when the intensity is 60 mw/cm2

Reference the textbook problem 6.12. Design a system using the photoconductive cell in Figure 6.9 to measure and display light intensity. Make the design such that 20 to 100 mW/cm2 produces an output of .2 to 1.0 V. What is the readout error w..

  Determine how far backed-off must the amplifier operate

If the SNR must be greater than 40 dBm, how far backed-off must the amplifier operate. Assume noise comes from a third-order intermodulation between two interferers with the same power level as the wanted signal.

  Explain what number is represented by the binary value

This will allow us to represent 256 numbers in that range, and there are only 6 integers in that range, so we'll be able to represent 250non-integral values, such as, perhaps, 2.5. Assume we will use a representation with 0xff representing 5 and 0..

  Show that any two zero-mass particles have a cm frame

[Hint: As you should explain, this is equivalent to showing that the sum of two forward light-like vectors is forward time-like, unless the spatial parts are parallel.]
