Create a library file named weather.js that contains the definitions of your dew point and wind chill functions. Then, create a Web page named indexes.html that has text boxes where the user can enter the temperature, humidity, and wind speed. The page should load the weather.js library and call the appropriate functions to display the dew point or wind chill at the click of a button.

Question

Use your page to determine the dew point under the following conditions:

temperature = 85 F humidity = 60%
temperature = 95 F humidity = 75%
temperature = 100 F humidity = 90%

Use your page to determine the wind chill under the following conditions:

temperature = 20 F wind speed = 10 mph
temperature = 10 F wind speed = 20 mph
temperature = 0 F wind speed = 30 mph

Answer 1

```
function WindChill(temp, wind)
// Assumes: temp is a temperature in Fahrenheit,
// wind is wind speed in miles per hour
// Returns: the wind chill index (what the current conditions feel like)
{
return 35.74 + 0.6123*temp + (0.4275*temp - 35.75)*Math.pow(wind, 0.16);
}

function DewPoint(temp, humidity)
// Assumes: temp is a temperature in Fahrenheit,
// humidity is the relative humidity (0-100%)
// Returns: the temperature at which water vapor condenses
{
return (temp - (100 - humidity)/2.778);
}
