So protons and electrons are a bit like the two different ends of a battery: they have equal and opposite electric charges. Since an atom contains equal number of protons and electrons, it has no overall charge: the positive charges on all the protons are exactly balanced by the negative ...
The MHD equations are evolved using a directionally unsplit staggered mesh solver35, extended to three temperatures36, adding also the Biermann battery effect23,37,38. We include non-ideal effects such as explicit Spitzer resistivity, implicit thermal conduction and heat exchange, as well as multi...

A battery, labeled 50V, with grounds on both sides. A long horizontal wire that is labeled "pull this wire really tight". An AC source that is labeled 240V, shorted out, with a label on the short "Omit this if you're a wimp." An inductor that is labeled with "11kg". A Batman...
We assessed the psychometric properties of the scales through a confirmatory factor analysis (CFA) on each group. A battery of fit indices (Hu and Bentler 1999) calculated with AMOS 25.0.0, indicated a good model fit for non-users and users (see Model 2 and 3 in Table 1). In the next...
Electricity is added to recharge a battery. What is added to ADP to form ATP? Explain the relationship between muscles, ATP energy, and the calcium ion. When protons return via (blank) enzyme ATP is released. In glycolysis, the hydrolysis of ATP to ADP is used to derive the phosphorylati...
adding also the Biermann battery effect23,37,38. We include non-ideal effects such as explicit Spitzer resistivity, implicit thermal conduction and heat exchange, as well as multi-group radiation diffusion with multi-material tabulated opacities and equations of state. The laser energy deposition is...
only work for a finite grid. In addition, the orientation of the battery in physical space has no relation to its behavior in a circuit, only the points of connection matter. Think about what the battery is doing to generate a current. How does electric potential apply over an infinite ...
aFig.6 clearly shows that k = 100 is a turning point for the group size distribution. When k < 100, the group size distribution curve looks almost perfectly linear in the log-log scale, which in turn implies that the distribution follows a power-law as the model predicts. When k > 10...
