Speed, frequency and wavelength are interconnected to each other.
<h3>What happens to the wavelength if the frequency increases?</h3>
As a wavelength increases in size, its frequency and energy (E) decrease. As the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.
The wave speed is equal to the product of its frequency and wavelength, which shows the relationship between frequency and wavelength.
So we can conclude that speed, frequency and wavelength are interconnected to each other.

Answer:
0.5 m/s²
Explanation:
according to Newton's second law, we are goven a relationship between force, mass and acceleration, with the formula:
F = m×a
F for force
m for mass
a for acceleration
we use the given data and get:
20 = 40×a
we find a=20/40=0.5m/s²
