Laboratory angular momentum purpose to investigate conservation of angular momentum by indirectly measuring the moments of inertia and directly measuring the angular velocities for initial and final configurations of a system.
1. as a the square mass is moved closer to the axis of the rotation, will the angular velocity of the rotating platform increase, decrease, or remain the same?
2. what will be the angle between the tension force in the string and the radius (lever arm) of the spindle in part ii?
3. derive a formula for the moment of inertia you will calculate in part ii in terms of the quantities you will measure in this lab.

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
