Question

two quantities that have the same units have the same dimensionality.

True or False

Answer 1

True

Answer 2

ok?

Answer 3

True, because the dimensions tell you what someone is talking about. So, if they are the same you are talking about the same thing. For example ft, is 1 dim. while area ft2 is two dimensions, and volume ft3 is three dimensions. I can use dimensions only, and you'd
know exactly what I was talking about.
