4. (a) Given that the instantaneous flux in a magnetic circuit is $\Phi = \Phi_{max} \sin \omega t$ Wb, show that the rms value of induced voltage in secondary winding, $N_2$ of a transformer operating at a frequency of $f$ Hz is given by $E_2 = 4.44 f \Phi_{max} N_2$ volts. (b) A 3-phase 500 kVA 11/0.44 kV 50 Hz star/delta connected transformer gave the following line input readings on light load test: | Type of Test | Voltage (V) | Current (A) | Power (kW) | |---|---|---|---| | Open Circuit | 440 | 16 | 4.8 | | Short Circuit | 400 | 30 | 8.2 | Calculate all the equivalent circuit parameters per phase referred to the primary and also the currents when the secondary is delivering full load current at a power factor of 0.85 lagging.

Exercise 4 (4 points) In this exercise, we explore the concept of marginal rates of substitution further. Suppose I own 3 bananas and 6 apples, and you own 5 bananas and 10 apples. With \"bananas\" on the horizontal axis and \"apples\" on the vertical, the slope of my indifference curve at my current bundle is -2, and the slope of your indifference curve through your current bundle is -1. (2 points each) a) Draw two separate graphs one for me and my indifference curve and one for you, identify the MRS in each graph. (Like in slide 20 Chapter 2) b) Interpret my and your MRS, what does it mean that is -2 for me and -1 for you?

The two blocks in the figure(Figure 1) are connected by a massless rope that passes over a pulley. The pulley is 15 cm in diameter and has a mass of 3.0 kg. As the pulley turns, friction at the axle exerts a torque of magnitude 0.49 N \cdot m Part A If the blocks are released from rest, how long does it take the 4.0 kg block to reach the floor? Express your answer to two significant figures and include the appropriate units.
