UEFS-BA) Considere duas placas planas e paralelas, dispostas horizontalmente e uniformemente eletrizadas com cargas de sinais opostos, conforme a figura a seguir. O campo elétrico entre as placas é uniforme e tem intensidade 3 x 105 N/C. Uma pequena esfera P, de carga q e peso 6 x 10-1 N está em equilíbrio entre as placas. Determine a carga q da esfera em Coulomb

The step-down transformer gives a current of 10a at 24v if the primary voltage is 240v calculate the 1_primary current 2_the power input 3_the power output

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference

When electrons are added to the outermost shell of a carbon atom, it forms--an anion that has a larger anion that has a smaller cation that has a larger cation that has a smaller radius.
