Asolid circular disk has a mass of 1.2 kg and a radius of 0.16m. each of three identical thin rods has a mass of 0.16kg. the rods are attached perpendicularly to the plane of the disk at its outer edge to form a three-legged stool (see the drawing). find the moment of inertia of the stool with respect to an axis that is perpendicular to the plane of the disk at its center. (hint: when considering the moment of inertia of each rod, note that all of the mass of each rod is located at the same perpendicular distance from the axis.

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?
