Take a look at the figure. the distance h a body will move in free fall is expressed by the formula shown. if g = 980 centimeters per second2 and t = 20 seconds, what is the distance? a. 368,000 centimeters b. 9,800 centimeters c. 49,000 centimeters d. 196,000 centimeters

Option D 196000 cm is the answer.

Step-by-step explanation:

By the given formula we have to calculate the distance h a body will move in free fall.

Here h = height, covered in t seconds

        g = 980 cm / second

and  t = 20 seconds

So by putting these values in the formula

h = (980) (20)²

  = × 400 × 980

  = 200 × 980

  = 196000 cm

Option D 196000 cm is the answer.

"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).
