A camel runs until reaching its top speed. A graph of its velocity over time is shown below.

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.

The three classes of rocks are sedimentary, metamorphic, and igneous. how are rocks classified into one of these three groups?

Boiling water is an example of physical change. true or false
