The following glucose tolerance test results are indicative of what state? Glucose values as assayed by glucose oxidase method are fasting, 130 mg/dL; 60 minutes, 225 mg/dL; and 120 minutes, 205 mg/dL.

Three point charges, -2.00 μC, +4.00 μC, and +6.00 μC, are located along the x-axis as shown in the figure. What is the electric potential (relative to infinity) at point P due to these charges? 

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? 

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.

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

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? 

Two equally charged tiny spheres of mass 1.0 g are placed 2.0 cm apart. When released, they begin to accelerate away from each other at What is the magnitude of the charge on each sphere, assuming only that the electric force is present? 

Four 2.0-µC point are at the corners of a rectangle with sides of length 3.0 cm and 4.0 cm. What is the electric potential (relative to infinity) at the midpoint of the rectangle? 

The length of a certain wire is kept same while its radius is doubled. What is the new resistance of this wire?
