Hi there!
Recall the equation for weight.

W = Weight (N)
M = Mass (kg)
g = acceleration due to gravity (m/s²)
The weight of an object depends upon its MASS and the strength of the GRAVITATIONAL field. We can solve for weight:

Answer: D. Albedo
Explanation:
The proportion of total light incident on surface that is reflected back is called its albedo. These are typical features of an astronomical body. It is a dimension less quantity and its value ranges from 0 to 1. Light surfaces reflect larger amount of light than dark surfaces. This feature can be clearly seen on planet Mars and the Moon.
Thus, the fraction of the total radiation that is reflected by any surface is called its <u>Albedo.</u>

<em>-------------------------------------------------------------</em>
<u><em>Loudness</em></u><em> refers to how a sound seems to a listener, whether it's loud or soft. </em>
<em>___________________________</em>
<u><em>Intensity </em></u><em> is the sound power per unit area. It is independent of the sensitivity of the human ears.</em>
<em>___________________________</em>
<em>The loudness of a sound relates the intensity of any given sound to the intensity at the threshold of hearing. It is measured in decibels (dB).</em>
