Moreover, pressure does not have to be measured along the wall of a container but rather can be measured as the force per unit area along any plane. Air pressure, for example, is a function of the weight of the air pushing down on Earth. Thus, as the altitude increases, pressure decreases.
physical features. The American Bobtail is a powerful and heavy cat with strong bones and muscles. Its medium-length legs complement the torso displaying powerful muscles and strong bones. The tail, which differentiates it from other breeds, is short-being between 2.5 cm to 10 cm (1 inch - 4 inches) in length. The tail should be flexible and can be slightly curled or even 'knotted'. Despite the length, this little tail has a good plume and long, shaggy, thick hair covers the tail.
Bobcats range in length from 65 to 105 cm, with the tail adding an extra 11 to 19 cm (bobcats got their name because of their short tails). They are 45 to 58 cm high at the shoulder and weigh between 4 and 15 kg. Bobcat fur can be various shades of buff and brown, with dark brown or black stripes and spots on some parts of the body. The tip of the tail and the backs of the ears are black. They have short ear tufts, and ruffs of hair on the side of the head, giving the appearance of sideburns.
