Carlos Measured the link of a book to be 21 cm the actual length of a book is 23cm which of these is closest to the percent error for Diego's measurements

8.70%

Step-by-step explanation:

Percent error is calculated as:

= (Accepted value - Experimental value) / Accepted value × 100

= (23 - 21) / 23 × 100

= 2/23 × 100

= 8.70%

The percentage error is 8.70%

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:
