If an object is dropped from a height of h meters and hits the ground in t seconds, then t = *square root of h/4.9* Suppose that an object is dropped from the top of a building that is 266.56 meters tall. How long does it take to hit the ground? Round your answer to the nearest tenth.

t = 7.4 seconds

Step-by-step explanation:

Hi, to answer this question we simply have to substitute h=266.56 in the equation given:

t = √ (h/4.9)

Where t is the time in seconds.

Replacing the value of h and solving for t:

t = √ (266.56/4.9)

t = √ (54.4)

t=7.3756

Since the number after the tenth decimal is greater than 5:

t = 7.4 seconds

"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).

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
