A Celestial Object Called a Pulsar Emits Its Light in Short

question 22

Short Answer

A celestial object called a pulsar emits its light in short bursts that are synchronised with its rotation. A pulsar in the Crab Nebula is rotating at a rate of 30 revolutions/second. What is the maximum radius of the pulsar, if no part of its surface can move faster than the speed of light (3 *108 m/s)?

Definitions:

Inductive Reactance

The opposition to alternating current flow due to the inductance of a component or circuit, measured in ohms.

Reactive Power

Also called wattless power. Calculated by multiplying reactive voltage by reactive current. Can be produced by inductive or capacitive loads.

Inductive Reactance

The opposition an inductor provides to alternating current, directly proportional to the frequency of the current.

Pure Inductive

Refers to a circuit element or circuit that purely has inductance without any resistance, ideally opposing changes in current by generating a magnetic field.
