## Step1For question 19, we need to understand the concept of kinetic energy. Kinetic energy is the energy an object possesses due to its motion. The formula for kinetic energy is , where is the mass of the object and is its velocity. When comparing the kinetic energy of a moving head at 15 mph to that of a sledgehammer or a softball, we need to consider the mass and velocity of each object. A moving head at 15 mph would have significantly more kinetic energy than a softball due to the difference in mass and velocity. A sledgehammer, being much heavier, would also have a higher kinetic energy at the same speed. Therefore, the statement that hitting your head at 15 mph has the same force of impact as being hit with a sledgehammer or a softball is not accurate.## Step2For question 20, we need to understand the legal implications of driving under the influence (DUI) with an underage passenger. In many jurisdictions, DUI laws are strict, especially when an underage passenger is involved. These laws are designed to protect young passengers from the dangers of drunk driving. Given the severity of the offense and the potential harm it can cause, it is plausible that one could face jail time for such a violation.## Step3For question 21, we need to understand the societal cost of underage alcohol use. The cost to society for underage alcohol use is a significant figure that reflects the economic impact of this issue. The options given are in different orders of magnitude: thousand, million, and billion. The correct answer would be the one that accurately represents the scale of the societal cost associated with underage alcohol use.## Step4For question 22, we need to understand the effects of alcohol on human behavior. Alcohol is a depressant that affects the central nervous system. One of its effects is the reduction of inhibitions, which can lead to impaired judgment and risky behaviors. Increased inhibitions or increased elation are not typical effects of alcohol consumption. Instead, alcohol usually leads to a decrease in inhibitions, making individuals more likely to engage in behaviors they might otherwise avoid.
