A 600 KVA, 3.464 KV 3-phase star-connected 4-pole synchronous generator is operating at full load and 0.866 power factor lagging, and field current of 18 Amps. The machine has a synchronous reactance of 10 ohms and negligible armature resistance. 50 points a. Find the generator full load power angle. b. With the same prime mover torque, and field current, if the machine synchronous reactance is doubled, what will be the new machine current, power factor, and power angle

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
