An Oscillating LC Circuit Has a Resonant Frequency of 1

question 47

Multiple Choice

An oscillating LC circuit has a resonant frequency of 1.2 × 10⁶ Hz. The diagram shows the system at t = 0 s when there is no charge on the capacitor and the current is in the direction shown. At this time, the energy stored in the inductor is 2.5 × 10^-7 J.
-Determine the numerical value of the capacitance.

• B)3.6 × 10^-11 F
• C)4.4 × 10^-11 F
• D)6.8 × 10^-11 F
• E)8.8 × 10^-11 F

Natural Environment

The surroundings or conditions in which a person, animal, or plant lives or operates, not significantly altered by human activity.

Control Group

In experimental research, the group of participants that does not receive the experimental treatment or intervention, used as a baseline to compare the effects of the treatment.

Comparison Group

A group of subjects not exposed to the experimental treatment or intervention in a research study, used as a benchmark to assess the effect of such treatment.

Standard Group

A standard group, often comparable to a control group, refers to a group of subjects in an experimental setting who are exposed to the usual or benchmark conditions, enabling comparison to experimental outcomes.
