Question

How do you best determine whether j/m^2 and m*s^2/n are equivalent units?

a. compare the written form of the units to see if they look the same.
b. determine if the formulas that each unit came from are the same.
c. notice that one unit contains joules and the other newtons.
d. express them both in terms of si base units.

Answer 1

I think the correct answer from the choices listed above is option D. The best way to determine whether  j/m^2 and m*s^2/n are equivalent units would be to  express them both in terms of si base units. Hope this answers the question. Have a nice day.

Answer 2

The best way is to break all secondary units into the primary (base) units. For example, N is a secondary unit which can be broken down into m kg s^-2, and so on. and joule is N-m, or to the base, m^2 kg s-2 So you can compare the base units to see if they are equivalent.
