HW Question E1, when do we convert units?

Postby Cienna Henry 1J » Wed Oct 03, 2018 7:47 pm

In the solutions manual, the answer for question E1 from the homework was converted to kilometers. What wording in the question hints that I am supposed to convert units?

Hi!

So in this question, it doesn't explicitly say what unit of distance was expected. SI says distance is in meters, so that would be your safest bet if the units weren't specified. I suppose km makes more sense because it's such a large distance, but I don't think your answer's wrong. As long as you had 1.73 * 10^14 m, you should be good to go.

Hope that helps!
