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

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.

Ascientific blank must be testable and capable of being proven false?

Ashot putter releases the shot some distance above the level ground with a velocity of 12.0 m/s, 51.0 ∘above the horizontal. the shot hits the ground 2.08 s later. you can ignore air resistance. how far did she throw the shot?
