Answer:
The effect of this rotation on the person on the surface is the sky is moving, like an apparent diurnal motion.
Explanation:
<em>For an observer at a fixed position on Earth, the rotation of earth makes it appear as if the sky is revolving around the earth. In other words, if a person is standing for long enough in a field at night, it looks like the sky is moving, not the person. This motion is called "apparent diurnal motion." </em>
<em>Diurnal means having to do with a day, in a sense of a 24- hour period.</em>
Hello!
When hydrogen runs out in a star, it can no longer perform nuclear fusion where hydrogen nuclei combine to create helium. This will stop fusion.
Hope this helps!
The amount of work done by the student in carrying the backpack is 30.6 J
<h3>Definition of workdone </h3>
Workdone is defined as the product of force and distance moved in the direction of the force.
Work done (Wd) = Force (F) × distance (d)
Wd = Fd
Also,
Force (F) = mass (m) × acceleration (a)
F = ma
Therefore,
Wd = (ma) × d
With the above formula, we can obtain the work done by the student.
<h3>How to determine the Workdone </h3>
From the question given above, the following data were obtained:
- Mass (m) = 12 Kg
- Acceleration (a) = 0.51 m/s²
- Distance (d) = 5 m
- Workdone (Wd) =?
Wd = (ma) × d
Wd = 12 × 0.51 × 5
Wd = 30.6 J

Answer:
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.Explanation:
