Why is the distance calculation multiplied by one half in this …
2010年6月24日 · When I learn physics I like to visualize what is happening in my head. I can understand why this problem is multiplied by t^2; from my rational it is to get (m/s^2) just to meters. But why is this equation multiplied by one half? I do not understand why this happens. Can someone please...

matrices - Transpose of inverse vs inverse of transpose
2024年1月25日 · By the way, while what you say is technically true, what the OP asked for wasn't a proof of $(AB)^T=B^TA^T$, but $(A^{-1}))^T=(A^T)^{-1}$, and the latter equality does hold in the $1\times1$ case even when the ring is not commutative. $\endgroup$

Convert cm^-1 to eV: Solve with Solution - Physics Forums
2005年4月14日 · The conversion factor to convert cm^-1 to eV is 1 cm^-1 = 0.00012398 eV. This can be derived from the relationship between energy and wavelength, where energy is equal to Planck's constant (h) times the speed of light (c) divided by the wavelength.
