question 22

Multiple Choice

An uncharged parallel plate capacitor with an air gap is connected to a 6.0-V battery.After charging,the energy stored in the capacitor is 40 nJ.Without disconnecting the capacitor from the battery,a dielectric material is inserted into the air gap and an additional 200 nJ of energy flows from the battery to the capacitor.What is the dielectric constant of the material?

• A)0.2
• B)1.0
• C)3.0
• D)5.0
• E)6.0

Definitions:

Positive Constants

Fixed values greater than zero that appear consistently within a mathematical equation or expression.

Isoquant Slope

The slope of an isoquant curve represents the rate at which one input can be substituted for another while maintaining the same level of output in production theory.

Input

Resources such as labor, materials, and capital that are used in the production process to create goods or services.

Returns To Scale

The speed at which production levels rise in reaction to an equal rise in all resources, including labor and capital.
