The same boy flies the kite that is now 100 feet above the ground. if the string is pulled out at 10ft/min because the wind carries the kite horizontally away from the boy, what is the rate of change of the angle the kite makes with the vertical when the angle is 30 degrees?

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
