Cover Test. While there are many ways for your eye doctor to check how your eyes work together, the cover test is the simplest and most common. During a cover test, your eye doctor will ask you to focus on a small object across the room and will then cover each of your eyes alternately while you stare at the target.
Hooke's Law states that the restoring force of a spring is directly proportional to a small displacement. In equation form, we write. F = -kx. where x is the size of the displacement.
In 1665 Hooke published Micrographia, a book describing observations made with microscopes and telescopes, as well as some original work in biology. Hooke coined the term cell for describing biological organisms, the term being suggested by the resemblance of plant cells to cells of a honeycomb.uch of Hooke's scientific work was conducted in his capacity as curator of experiments of the Royal Society, a post he held from 1662, or as part of the household of Robert Boyle.
