Aseparately excited d. generator has armature
resistance of 0.1ohms and brush drop 2v. when
running at 1000 rimp, it delivers a current of
100a at 250v to a load of constant resistance
if the generater speed drop to 700 r. m. p. find
the current delivered to the load.

Use the information presented in the graph to answer the questions. which segments show acceleration? which segment indicates that the object is slowing down? what is the velocity of segment b? what is the acceleration of segment b?

Awind turbine is rotating counterclockwise at 0.5 rev/s and slows to a stop in 10 s. its blades are 20 m in length. (a) what is the angular acceleration of the turbine? (b) what is the centripetal acceleration of the tip of the blades at t=0s? (c) what is the magnitude and direction of the total linear acceleration of the tip of the blades at t=0s?

What is a subatomic particle with a negative charge and very little mass?
