The Equation for the Luminosity of a Star in Terms

question 188

Multiple Choice

The equation for the luminosity of a star in terms of its surface temperature is L = (surface area) σT⁴,where σ is the Stefan-Boltzmann constant.This suggests that,when a plot is made of luminosities versus temperature:

• A) stars of the same temperature but different radii should occupy different points on the plot.
• B) all stars should plot along the line.
• C) larger stars must have higher temperatures.
• D) smaller stars must have higher temperatures.

Definitions:

Pollinators

Organisms that carry pollen from the male structures (anthers) to the female structures (stigmas) of flowers, facilitating plant reproduction.

Nectar-producers

Organisms, typically flowering plants, that generate nectar, a sweet fluid attracting pollinators such as bees and hummingbirds.

Male Part

Refers to the stamen in plants, which is the pollen-producing reproductive organ.

Anther

The part of a flower's stamen that contains the pollen, which is necessary for fertilization.
