the magnitude of the electric field between the two circular parallel plates in figure below is a = (4.0x 105 ) (6.0x 104 t), with e in volts per meter and t in seconds. at t = 0, e is upward. the plate area is 4.0x102 m 2 . for t 0,what are the (a) magnitude and (b) direction (up or down) of the displacement current between the plates and (c) is the direction of the induced magnetic field clockwise or counterclockwise in the figure?

this is a good question! i'll do some research and come back when i have the answer!

current flows in a wire

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
