Write the order of magnitude of the following measurements:

(i)

25,710,000 \mathrm{~m}

(ii)

0.00000521 \mathrm{~kg}

View answer and explanation

Correct option: A

(i) 7; (ii)

-5

Option A is correct because

25,710,000 \approx 10^7

and

0.00000521 \approx 10^{-5}

, so the orders of magnitude are 7 and -5 respectively.
