For a fixed initial speed, the range of a projectile is determined by the angle at which it is fired. For all but the maximum, there are two angles that give the same range. Considering factors that might affect the ability of an archer to hit a target, such as wind, explain why the smaller angle (cl

Consider a state with a fixed prison capacity of 1,000. When a law is passed establishing a minimum term of 10 years, (twice the current average term), the state cuts the number of prisoners in half, cutting the probability of imprison- ment for crime in half. Use a graph like Figure 133 to illustrat

Abundant trans bonds make partially hydrogenated vegetable oil a very unhealthy food choice. Vegetable oil can also be hydrogenated until it becomes fully saturated with hydrogen atoms. Would the physical properties of the hydrogenated and partially hydrogenated oils differ? If so, how and why would
