Answer:
it should be changes in velocity
Explanation:
I hope this helps!
Albert Einstein created this equation. It means that the formula shows that mass can be converted into energy, and energy can be converted into mass. Einstein made this equation 100+ years ago, and yes, he was right with the theory.

A triangle is the symbol used to indicate a fulcrum in a lever, a triangle has three sides and three vertices.
<h3>What is a fulcrum?</h3>
A fulcrum is a pivot that has a base and a point that serves as a balance for a lever.
<h3>What is a lever?</h3>
Basically a lever is a simple machine that is a beam with two sides pivoted to fulcrum.
A lever has Load, Effort and the last part is fulcrum

Given data:
- It is a graphical display where the data is grouped in to ranges
- A diagram consists rectangles, whose area is proportional to frequency of a variable and whose width is equal to the class interval.
- It is an accurate representation of the distribution of numerical data.
<em>From Figure:</em>
Each box in the graph (small rectangle box) is assumed to be one download. So, in the graph the time between 8 p.m to 9 p.m, the number of downloads are 8.75 approximately (because the last box is incomplete, therefore 8 complete boxes and 9th is more than half).
<em>So, We conclude that the total number of downloads are approximately 9 in the time span of 8 p.m. to 9 p.m.</em>
From the calculations, the mass of the pole is 82 Kg.
<h3>What is potential energy?</h3>
The term potential energy has to do with the energy that is possessed by a body by virtue of its position.
Given that;
height = 6.15 m
PE = 4942 J
mass = ??
g = 9.8 m/s^2
Now
PE = mgh
m = PE/gh
m = 4942 J/9.8 m/s^2 * 6.15 m
m = 82 Kg
