Some compounds are classified as acids or bases. The ph scale shows how acidic or how basic these compounds are the lower the ph the more acidic a compounds is the higher the ph the more basic it is.

A cylindrical can holds 1 liters (1000 cm^3) of liquid. How should the height and radius be chosen to minimize the amount of material needed to manufacture the can?

Ball A has a mass of 0.200 kilograms. Ball A, traveling at a velocity of 2 meters/second in the + x direction, hits a stationary ball B of the same mass. After the collision, ball B bounces off at a positive angle with respect to the + x-direction.
