To convert 1 meV to Å using the equation 1 (E)1/2 = 9.045Å-1, it is necessary to solve for Å by substituting E with 1 meV. The Å represents the unit of length, specifically angstroms, commonly used in atomic and molecular scales. The values 1 and 9.045 are coefficients in the equation, with 9.045 being a conversion factor. The discussion highlights the need to convert energy units from meV to Joules for standard calculations, but the specific conversion to Å is not straightforward. Clarification on the units and the equation's context is essential for accurate calculations.

Homework Statement


Hi

I am told that 1 (E)1/2 = 9.045Å-1, where E is the energy in meV. How do I find out what 1 meV is in Å from that? All I can get is the correspondence between meV and Å-2, not meV and Å.

What does the Å represent?
Do the 1 and 9.045 have units?
Maybe your job is just to solve the equation for Å, and put in 1 MeV for E. Not a clear question in my opinion - if you have posted all of it. Normally the 1 MeV would be changed into standard units of energy (Joules) but I don't know what you should do in this case.
 

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
