The distance d that a spring is stretched by a hanging object varies directly as the weight w of the object. if a 27-kg object stretches a spring 53 cm, find the distance when the weight is 13-kg. round your answer to the nearest whole centimeter.

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:

let's fu(!
