We can rearrange the equation R=ρLAR=ρLA to find the cross-sectional area A of the filament from the given information. Then its diameter can be found by assuming it has a circular cross-section. Solution The cross-sectional area, found by rearranging the expression for the resistance of...
For example, if use of the equation expressing a particular concept is worth one point, and a student’s solution contains the application of that equation to the problem but the student does not write the basic equation, the point is still awarded. 4. The scoring guidelines typically show ...

I'd have to solve the Schrödinger equation and find the the wavefunctions for the hydrogen atom to find out something like that." Here are those wavefunctions and energy levels all spelled out for you. If you were just wondering what the energy levels of the hydrogen atom are,and how ...
For the 2021-2022 session of INPhO, only one qualifier examination was conducted known as the Indian Olympiad Qualifier for Physics (IOQP). This examination had two parts: Part 1: National Standard Examination for Physics (NSEP) and Part 2: Indian National Physics Olympiad (INPhO). ...
The equation for a torus defined implicitly is, $$(\sqrt{x^{2} + y^{2}} -a)^{2} + z^{2} = b^{2}$$ When solving for the z-axis in the torus equation, we get complex solutions, from the empty intersection: $$z = - \sqrt{b^{2} - a^{2}}$$ $$z = \sqrt{b^{2...
