Answer:E
Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly. Wavelength always increases with speed, as frequency is fixed at source and speed= freq x wavelength
The speed of sound in room temperature air is 346 meters per second.
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>
The object is fixed relative to the motion you are trying to describe.
