Have a universal record base. Everyone is able to understand the data compiled since the same measurement systems are being used around the world. This is just to simplify all of the information.
The angle of reflection is 42 degrees because it says the angle of incidence is equal to the angle of reflection
Answer:
<h3><u>Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields. ... They are deflected neither by the electric field, nor by the magnetic field.</u></h3>

The graph of the potential energy pass through zero origin, cuts across positive x-axis and negative x-axis.
<h3>Slope of the graph</h3>
The slope of the graph when the potential energy of a particle constrained in on x-axis is determined as follows;
F = -dU/dx
-dU = Fdx
dU = -Fdx
U = -∫(kx + ax³)dx
U = kx²/2 - ax⁴/4
When, x = 0, U = 0
When U = 0;

The graph of the potential energy pass through zero origin, cuts across positive x-axis and negative x-axis.
Complete question is below:
Suppose that the potential energy of a particle constrainedon x-axis and subjected to a force in the same direction, at a fuction of F(x) = -kx + ax³.
Find the functional form of the potential energy.
