12. A ball of modeling clay has a mass of 240 g and a diameter of 11 cm with an axis of rotation through the center. 13. A wooden dowel rod has a mass of 0.88 kg and a length of 1.2 m with an axis of rotation through the end.

14. A bolt in a table saw needs to be tightened. Jim applies a force of 82 N with a wrench that is held 60° from the perpendicular and is 42 cm long. What torque does the wrench exert on the bolt?

15. Christopher, who weighs 240 N, and Thomas, who weighs 185 N, are sitting on opposite ends of a balanced seesaw. If Thomas is sitting 1.2 m from the balance point, how far is Christopher sitting from the balance point?

step-by-step explanation:

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
