A30-kva 8000/230-v distribution transformer has an impedance referred to the primary of 20 + j100 ω. the components of the excitation branch referred to the primary side are rc =100 kω and xm =20 kω (a) if the primary voltage is 7967 v and the load impedance is zl= 2.0 + j0.7 ω. what is the secondary voltage of the transformer? what is the voltage regulation of the transformer? (b) if the load is disconnected and a capacitor of –j3.0 ω is connected in its place, what is

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
