While Traveling the Galaxy in a Spacecraft, You and a Colleague

question 46

Essay

While traveling the galaxy in a spacecraft, you and a colleague set out to investigate a 10M _$\odot$ black hole. Your colleague hops aboard an escape pod and drops into a circular orbit around the black hole maintaining a distance of 50 km from it, while you remain much farther away inside the spacecraft. After doing some experiments to measure the strength of gravity, your colleague signals the results back to you using a green laser. What would you see, and why?

Identify and apply the concept of the mode as a measure of central tendency and its relative strengths and weaknesses.

Differentiate between the characteristics of a sample (statistic) and a population (parameter).

Recognize and explain the effects of outliers on measures of central tendency.

Understand the implications of using median, mean, and mode for data analysis and hypothesis testing.

Definitions:

Inductive Reactance

The opposition to the change of current flow through an inductor in an AC circuit, measured in ohms.

Series RL Circuit

An electrical circuit consisting of a resistor (R) and an inductor (L) connected in series, used to study the behavior of circuits with resistive and inductive components.

Inductive Reactance

The opposition to the change in current in an inductor, depending on the frequency of the current and the inductance.

Angle Theta

Generally used to express the phase angle difference between voltage and current in a reactive circuit.
