Temperature & Times for Cooking Chicken. When cooking chicken, make sure to cook thoroughly, so there is no pink and the flesh is opaque all the way through. If you are using a meat thermometer, you can use it to determine when the meat is done; chicken should be cooked to 165 degrees.
Hooke's law. When studying springs and elasticity, the 17áµÊ° century physicist Robert Hooke noticed that the stress vs strain curve for many materials has a linear region. Within certain limits, the force required to stretch an elastic object such as a metal spring is directly proportional to the extension of the spring.
(The elastic limit is the point at which the spring no longer returns to its original shape. Treat these springs gently!). In this activity, you will use Hooke's Law to graphically determine the spring constant of a helical spring. You will NOT be using the dual-range force sensor or the motion sensor in this activity.
