Why did you test the resistance of the wire?
a. the current flowing through the lightbulb was too low. decreasing resistance would increase the current.
b. the current flowing through the lightbulb was too high. increasing resistance would decrease the current.
c. the current flowing through the lightbulb was too high. decreasing resistance would decrease the current.
d, the current flowing through the lightbulb was too low. increasing resistance would increase the current.

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:
