Most likely, the equation is
<em>Acceleration over a period of time = </em>
<em>(change in speed during the period of time)</em>
<em>divided by</em>
<em>(length of the period of time) .</em>
for any piece of the graph.
Technically? It's not wrong. A star is a ball of gas that is held together by it's own gravity of which it constantly struggles against. Gravity constantly works to try and make the star collapse. However, stars are extremely hot at their cores which help the star push against it's own gravity creating a sort of equilibrium. So long as the star continues to push against gravity, it will not collapse, however eventually a star will lose its energy and eventually collapse into a black hole.
When object distance is smaller than the focal length of a convex lens, then the rays diverge.
Here, object distance = 20 cm
focal length = 25 cm
20 < 25
Thus, the lens are <u>diverging</u>

<h3>
What is focal length?</h3>
The fundamental description of a camera lens is its focal length, which is often expressed in millimeters (mm). It is not a measurement of the physical length of a lens.
But rather a calculation of the optical distance between the focal plane of the camera's digital sensor or 35mm film to the location where light rays converge to make a sharp image of an object. When a lens is focussed to infinity, its focal length can be calculated.

Answer:
480 m
Explanation:
If the shoe is falling for 6 seconds and the helicopter is falling at 80 m/s you would mutiply 6*80=480
