B) 7
C) 9
D) 10

Question

Quizplus · Accepted Answer

To find the number of orders of magnitude between the two distances, we need to subtract the log of the smaller distance from the log of the larger distance.

log(10⁹ m) - log(10⁰ m) = log(10⁹) - log(10⁰) = 9 - 0 = 9 orders of magnitude.

Therefore, the answer is C, 9.
