Consider the pictured representations of electromagnetic waves. Three pictured waves centered around lines of the same length. Wave A has 1.5 waves on the line. Wave B has 2 waves on the line. Wave C has 1 wave on the line. Which electromagnetic wave corresponds to each description

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
