Suppose a solid uniform sphere of mass m and radius r rolls without slipping down an inclined plane starting from rest. the angular velocity of the sphere at the bottom of the incline depends on: ) the mass of the sphere.
b) the radius of the sphere.
c) both the mass and the radius of the sphere.
d) neither the mass nor the radius of the sphere.

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

Argon, neon, and xenon are examples of

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
