Question 41 Philip Zimbardo's study of a simulated prison environment that used college students as prisoners and prison guards: O all of these O indicated that social interactions are not influenced by social structure characteristics. O demonstrated that a social structure can influence the type of social interactions that occur. O indicated that it is impossible to replicate a "real life" situation in a laboratory.

(a) A water trough (pictured below) has a horizontal length of 4 meters and cross sections perpendicular to the length are equilateral triangles with sides of length 2 meters. The acceleration due to gravity is 9.8(m)/(s^(2)) and water has a density of 1000k(g)/(m^(3)). Write down an integral which expresses how much work is required to empty the full trough by pumping the water out through the top? (b) How does your answer change if the trough is only filled up to a height of 1m ? (c) How does your answer change if the water is not only pumped to the top of the tank, but to 2 meters above the top of the tank? 10.

ECE 2011 Experiment 5 Prelab Name Section Keep a copy of this for use in the Laboratory. 1. Compute the period of a waveform which has frequency 2.5 kHz. 2. Compute the frequency of a square wave which is low for 20 µs and high for 20 µs of each cycle. 3. Compute (a) the peak voltage and (b) the RMS voltage of a sinusoid wave that has peak-to- peak voltage 3 V. 4. A square wave has amplitude 0 V for the low voltage and 4 V for the high voltage. Calculate the average voltage by integrating over one period of the waveform. Hint: the equation for a square wave will be a piecewise function and it will be convenient to start the integration where the voltage changes; for example in this problem we could define that during the first half of the period the voltage is 0 V and for the second half of the period the voltage is 4 V.
