Please help I’ve been stuck on this for a while! Todd purchased a jumper for his infant son. The jumper clamps to the top of a door frame and has a spring from
which the body of the jumper hangs to allow the infant to jump up and down. Included with the jumper are small
weights, each identical in
weight and size. The weights allow the user to adjust the initial height of the jumper by
stretching the spring a certain distance. Todd adds 8 of the weights and notes the spring stretches 2 centimeters.
a. According to Hook's Law, the amount that a spring is stretched, s, varies directly with the force applied to the
spring by the weights, F. Write an equation that relates F and s for the spring on the jumper
b. Using your equation from part a, find the stretch in the spring if Todd applies 14 of the included weights to the
spring
c. Using your equation from part a find the number of weights necessary for the spring to stretch 7 centimeters.

"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).
