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

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
