Problem 2. The circuit of Fig. 2 is composed of two transformers operating at 50 Hz. The voltage source is 240 V rms with phase 30 degrees. a. Move all the circuit to the primary of the transformer 1 (i.e. by eliminating both transformers). (5 marks) b. Calculate the load current and the load impedance. (10 mark) c. If we want to correct the power factor of the total load connected to the secondary of the second transformer to 1, what should be the size of the capacitor connected between terminals a and b? (10 marks) d. If we want to be sure that the source is not producing any reactive power, what should be the size of the capacitor connected between terminals a and b? (5 marks) $V_{rms} = 240 <30^{\circ}$ $n_1 = 30$ $n_2 = 10$ $n_1 = 2$ $n_2 = 4$ $R = 10 \Omega$ $L = 0.01 H$ Load PF=0.8 Lag P=10kw

According to Amartya Sen, development should be seen as a non-political concept that focuses on the net income of a country. It should be viewed as a purely economic process. It should be assessed by material output measures such as GNI per capita. It should be seen as a process of expanding the real freedoms that people experience.

1. A researcher compared the effects of three different instructional techniques to a control condition and each other (k=4). She tested students' ability to do statistics problems. For each condition, she tested four students. The results are summarized below (Note: SST is provided to use as a check, do not use it to calculate either SSB, or SSW): CC IT1 IT2 IT3 T?=20 T?=32 T?=20 T?=8 SS?=12 SS?=14 SS?=12 SS?=10 SST=120 Run a complete hypothesis test, with ? = .05, to determine if there were any reliable differences between the treatment groups. Do the results show that technique 1 is better than technique 2? Explain your answer. If she had done a t-test instead, what t and df would she have found? 2. The following SPSS tables summarize the results of a two-factor ANOVA evaluating an independent-measures experiment with three levels of Herbal Treatment crossed with two levels of Patient Attitude. Do hypothesis tests, with ? = .05, for main effects and interactions. Summarize the results in a matrix table, including row, and column means. Then, summarize the results in a graph to illustrate whether or not there is an interaction. Describe any main effects and interactions that were found.
