A to-scale figure of the space station is 4 inches long. if you know the scale for the space station is 1 inch to 5 yards, how long is the actual space station?

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:

43

step-by-step explanation:

not sure if this is supposed to be a trick question. 43 is the only one that makes any sense.
