A Telescope Is Set Up in Introductory Physics Lab Using $\times$

question 41

Multiple Choice

A telescope is set up in introductory physics lab using a 10 cm lens and a 50 cm lens.Since both lenses are the same diameter it is not evident which one to use as the eyepiece and which one to use as the objective.If one uses the 50 cm lens as the eyepiece,what power results?

• A) 500\(\times\)
• B) 5\(\times\)
• C) 0.2\(\times\)
• D) 0.002\(\times\)
• E) one cannot look through the system in this direction

Definitions:

RLC Series Circuit

An RLC series circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C) connected in series, exhibiting both resistive and reactive properties.

True Power

The actual power consumed by an electrical device in watts, calculated as the product of voltage, current, and the cosine of the phase angle between them.

Applied Voltage

The external voltage applied across a component or circuit, driving current through it according to Ohm's Law.

Apparent Power

The total power in an AC circuit, represented as the product of voltage and current without factoring in the phase angle, measured in Volt-Amperes (VA).
