While working on her science fair project Venus connected a battery to a circuit that contained a light bulb. Venus decided to change the battery to a higher voltage, but she kept the same light bulb.
What will happen to the brightness of the bulb?
A.
The brightness will increase because the current will decrease.
B.
The brightness will decrease because the current will increase.
C.
The brightness will increase because the current will increase.

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:
