question 96

Multiple Choice

An ideal parallel-plate capacitor consists of two parallel plates of area A separated by a distance d. This capacitor is connected across a battery that maintains a constant potential difference between
The plates. If the separation between the plates is now doubled, the magnitude of the charge on the
Plates will

• A) be cut in fourth.
• B) double.
• C) quadruple.
• D) not change.
• E) be cut in half.

Probability Density

A function that describes the relative likelihood for a continuous random variable to occur at a specific point.

Normally Distributed

A statistical distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

Standard Normal
