Answer:
The frequency of the wave is, f = 1 Hz
Explanation:
The half-wavelength of the wave can be found from the successive compression or rarefaction.
This is equal to the successive crest or trough.
The one wavelength is the wave that completes one cycle of vibration.
Therefore, the frequency of the wavelength is defined as the number of such vibrations per second. It is given by the formula
f = 1 /T or v/λ ( v - velocity of the wave)
= 1 / 1
= 1 Hz.
The unit of frequency is Hertz.
Since the rabbit is moving at constant velocity, therefore
the acceleration is zero, hence the increase in distance over time would simply
be:
x = v t
where v is velocity and t is time, x is distance
Since we are starting at x = 8.1 m, the equation of motion
would therefore be:
<span>x = 8.1 – 1.6 t</span>
I’m pretty sure you times them so 1 with A, 2 with e, 3 with C, and 4 with B
