A sample from a meteorite that landed on Earth has been analyzed, and the results shows that out of every 1,000 nuclei of potassium- 40 originally in the meteorite, only 125 are still present, meaning they have no yet decayed. How old is the meteorite (in yr)? (Hint: see the figure below) (Note: The half life of potassium- 40 is 1.3 billion years.)

An approximate model for a ceiling fan consists of a cylindrical disk with four thin rods extending from the disk's center, as in the figure below. The disk has mass 2.10 kg and radius 0.200 m. Each rod has mass 0.850 kg and is 0.680 m long. (Need help with part B) a) Find the ceiling fan's moment of inertia about a vertical axis through the disk's center. (Enter your answer in kg · m2.) --> My answer = 0.566 b) Friction exerts a constant torque of magnitude 0.119 N · m on the fan as it rotates. Find the magnitude of the constant torque provided by the fan's motor if the fan starts from rest and takes 15.0 s and 16.5 full revolutions to reach its maximum speed. (Enter your answer in N · m.)
