The combination of an applied force and a constant frictional force produces a constant total torque of 35.7 N·m on a wheel rotating about a fixed axis. The applied force acts for 6.05 s. During this time the angular speed of the wheel increases from 0 to 9.8 rad/s. The applied force is then removed, and the wheel comes to rest in 60.2 s. (a) Find the moment of inertia of the wheel. kg·m2 (b) Find the magnitude of the...

Which of the following statements are true? Enter all the correct items, e.g., enter AD. If none is correct, enter N: The uncertainty of the average counts-per-minute is always about 1 count per minute. β- radiation is equivalent to an electron expelled from an atomic nucleus. Background counts can be significant if the distance between the source and the Geiger counter is large. γ radiation readily penetrates lead (Pb) foil.
