Mathematically speaking, the energy of a wave is directionally proportional to the square of the amplitude of the wave Calculate
2 answers:
The energy of the wave is D) 16.0 units squared
Explanation:
The energy of a wave is directly proportional to the square of the amplitude of the wave.
Mathematically, this can be written as
where
E is the energy of the wave
A is its amplitude
For the wave in this problem, the amplitude is
A = 4 units
Therefore, assuming that the constant of proportionality is 1, the energy of this wave is
units squared

The strength of the electric field will be 215760 NC⁻¹. The concept of the electric field strength is used in the problem.
<h3>What is electric file strength?</h3>The electric field strength is defined as the ratio of electric force and charge. Its unit is NC⁻¹.
The given data in the problem is;
E is the Electric Field Strength
k is the Colomb's constant = 8.99 x 10⁹ N.m²/C²
q is the magnitude of charge = 6 μC = 6 x 10⁻⁶ C
r is the distance = 0.5 m
The electric field strength is given by the formula;
Hence the strength of the electric field will be 215760 NC⁻¹.
