A pendulum swings through an angle of 20° each second. If the pendulum is 60 inches long, how far does its tip move each second? If necessary, round to two decimal places.

i dont know sorry

step-by-step explanation:

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:

no
