g A 400 turn circular coil with a radius of 0.3 m is rotated through a quarter turn in 0.417 ms (this corresponds to 60 revolutions per second). Suppose the plane of the loop was initially perpendicular to a uniform magnetic field. If the average induced voltage is 10 kV, what is the magnitude of the magnetic field

The modern-day generator works on the principle of electromagnetic induction discovered by michael faraday in 1831-32. faraday discovered that the above flow of electric charges could be induced by moving an electrical conductor, such as a wire that contains electric charges, in a magnetic field.

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero. 

Did you ever figure out the right answers since you asked?
