When jupiter is a distance of 630 million kilometres from earth (4.2 astronomical units), it has an apparent angular diameter of 46 arcseconds (46/3600 of degree). calculate jupiter's diameter in kilometers, and state how many times larger this is than diameter of earth

Jupiter's diameter is 11 times greater than that of Earth

Explanation:

Given,

The distance between Jupiter and earth is 630 million km = D   km

Let, the angular diameter be  a = 46 arcseconds

Diameter of Jupiter be d

We know that Earth’s diameter = 12,742 km

According to the formula;

a (in arcseconds) =  

Substituting all the values in the equation;

46 =

Calculating for d;

d =  

d = 140,498.8728092502 km

The diameter of Jupiter is 140498.87 km

Therefore, Jupiter’s diameter is 11 times greater than Earth’s diameter.  

"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).
