Atrain from san francisco to san jose travels at an average speed of 72 miles per hour and takes 45 minutes for the trip. what is the distance from sf to sj?

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:

1260=3*6*7*10=3^2*2^2*7*5 perfect cude = 3^3*2^
