A 10.0-kg rod has a varying linear density that is symmetric about the midpoint of the rod. The moment of inertia about an axis perpendicular to the rod that passes through the rod 30.0 cm from its midpoint is 5.00 kg?m2
What is the moment of inertia about an axis perpendicular to the rod that passes through the rod 20.0 cm from its midpoint? A) 7.50 kg?m2 B) 4.50 kg?m2 C) 5.10 kg?m2 D) 4.90 kg?m2 E) Answer depends on whether the new axis is on the same side of the midpoint as the 30.0 cm distant axis or if its on the opposite side of the midpoint.
Three different resistance lightbulbs are connected to a 120-V outlet. The most power will be consumed by the circuit
A. when the most resistive bulb is in parallel with a series of the other two. B. when the bulbs are in parallel. C. when the bulbs are in series. D. when the least resistive bulb is in parallel with a series of the other two. E. The arrangement is unimportant because the voltage is the same in all cases.
