3) Earth is about 150 million km from the Sun, and the apparent brightness of the Sun in our sky is about 1,300 watts per square meter. Determine the apparent brightness we would measure for the Sun if we were located five times Earth's distance from the Sun. Answer: The Sun would appear 1/25 times as bright.
Answer:
See the answer below
Explanation:
The two correct options are:
1. <em>The student traveled the fastest between 4 and 5 minutes</em>
<em>2. The average speed of the student is 4 meters per minute</em>
Between 4 and 5 minutes, the approximate distance of 7 meters covered by the student is the longest of all the distances covered per minute. Since speed is a measure of distance covered relative to time, <u>it means that the student traveled the fastest between these periods.</u>
<em>The average speed is calculated by dividing the total distance traveled by a body by the total time taken to cover the distance. </em>
From the graph:
Total distance covered = 20
Total time taken = 5
Average speed = 20/5 = 4 meters per minute
<em>All the remaining conclusions are incorrect or indeterminate going by the information on the graph.</em>
Surface tension and surface energy are two very important concepts discussed in physics. The concepts of surface tension and surface energy are widely used in fields such as fluid mechanics, fluid dynamics, aerodynamics and various other fields. Surface tension is the net intermolecular force on the surface molecules of a liquid. Surface energy is the relevant energy of these bonds. In this article, we are going to discuss what surface tension and surface energy are, their applications, the definitions of surface tension and surface energy, their similarities, and finally the difference between surface tension and surface energy.
