## Study23 2 years ago Really stuck with this problem, not sure what to do: Consider a system where the three fundamentally important quantities are the speed of light c with dimensions [L]/[T], Planck's constant h with dimensions [M][L]^2/[T] and the mass of the proton mp with dimension [M]. What combination of ratios and/or products of c, h, and mp will yield a new quantity of dimensions [L]?

You might want to post this in the physics section

@williamnz I never get a response in physics, and this is sort of math related!

3. williamnz

That sucks. Well i'm guessing this is mechanics related.

Idk, I'm stumped, I tried 'bout 4 ratios, but none of them worked, sorry

Sorry

@raimj512 How do you approach this problem?

8. raimj512

well, you know how to come up with ratios, right? This is a physics question, but, it can be worked into a little bit of an algebraic expression(Kinda). c, h, mp can be used to make a semi-sort of an algebraic expression.
