Energy of wave depends on its amplitude and it is given as
here k = constant
A = amplitude
so energy will increase or decrease depends on the amplitude of the wave
So here if we need to check which wave has lower energy then we need to compare the amplitude.
If the amplitude is less then energy must be less
So please check in the figure that which wave out of A and B has lesser amplitude to find out the wave of lesser energy
The line leading a bracket around the balls, labeled A, represents the nucleus of the atom.
<h3>What is nucleus?</h3>
The nucleus constructs the major part of the atom where all the mass of atom is concentrated. The nucleus of the atom lies at the center, where protons and neutrons are placed.
2 red and 2 blue overlapping balls in the center are surrounded by a green, fuzzy, circular cloud with a white line running through it. 2 green balls sit on the white line, and a line leading a bracket around the balls is labeled a. a line leading to a bracket overlapping the white line is labeled b.
The red balls and the two overlapping balls in the center are representing the protons and neutrons.
Thus, the line leading a bracket around the balls, labeled A, represents the nucleus of the atom.

Answer: 0.9
Explanation:
For an inclined surface the coefficient of friction (n) is the ratio of the moving force (Fm) to the normal reaction (R) acting on the body.
n = Fm/R
Fm = WSintheta = mgsintheta
R = Wcostheta = mgcostheta
n = Wsintheta/Wcostheta
n = sintheta/costheta
n = tan theta
n = tan 42°
n = 0.9
Therefore, minimum coefficient of static friction between the vehicle’s tires and the road is 0.9
