AI Thread Summary

The discussion centers on rearranging the differential mode equation Vo=(V2-V1)*(Rf/R1) to isolate V1. The solution involves dividing by Rf/R1, leading to the equation V2-V1=Vo/(Rf/R1). By subtracting V2 and multiplying by -1, the final rearranged formula is V1=(-Vo/(Rf/R1))+V2. This transformation clarifies the relationship between the variables in the equation. The conversation effectively resolves the original query about isolating V1.

Hi, I was wondering how you would re-arrange the differntial mode equation :
Vo=(V2-V1)*(Rf/R1)
to have V1 as the subject of the formula - its been annoying me for ages.

thanks

Well...first of all, divide by Rf/R1
\frac{Vo}{Rf/R1}=V2-V1 THen we just subtract V2 and multiply by -1:
\frac{Vo}{Rf/R1}-V2=-V1
V1=\frac{-Vo}{Rf/R1}+V2

Thread 'Is space stretching or is new space being created?'

Do we even know? My understanding of dark energy is that particles come into existence, exert and outward force, then vanish. My problem with that is how, of course, then how does dark energy know to push everything in the same direction? The pressure exerted would be in all directions, even if the space was moving so why isn't stuff pushed all over the sky? Thanks - rev

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
