An electrolyte panel was performed on a patient in the emergency room. The following values were reported: Sodium: 150 mEq/L Potassium: 5 mEq/L Chloride: 110 mEq/L Bicarbonate: 30 mEq/L The anion gap (without using K) for this patient is:

A low plasma osmolality and low sodium would be expected in a patient with:

Assume the same parameters value as in question 21. The equilibrium employment  [increases, decreases, does not change] by ______  percent (to ______ workers ) computed as. . . .

Three identical 3.0-µC charges are placed at the vertices of an equilateral triangle that measures 30 cm on a side. What is the magnitude of the electrostatic force on any one of the charges? 

When a current flows through a metal wire, the moving charges are

Choose the correct shaped graph for the power dissipated by a resistor in series with an AC source. The source switches on at time t=0 and varies as a sine function. Ignore the portion of the graph before t=0.

Two 3.0 μC charges lie on the x-axis, one at the origin and the other at What is the potential (relative to infinity) due to these charges at a point at on the x-axis? 

Which of the following changes will increase the capacitance of a parallel-plate capacitor? (There could be more than one correct choice.)

How much energy is necessary to place three +2.0-µC point charges at the vertices of an equilateral triangle of side 2.0 cm if they started out extremely far away? 

How far apart should two protons be if the electrical force of repulsion on each one is equal to its weight on the earth? Answer to two significant figures in centimeters.
