Hi!
I believe the answer is A . energy transmitted by the cry of an eagle.
The particles of the medium oscillate only parallel to the motion of the wave transmitted by the cry of an eagle .
Hope it helps and have a wonderful day !

Answer:
Yes . Frictions was not included for the calculation for acceleration .
Explanation:
This is because we're considering the weight of an object which isn't acceleration i:e frictionless.
If friction is included, the equation for acceleration becomes.
F= ma,(Newton second law of motion)
where F=frictional force , m =mass of the object and a=acceleration..
So therefore, a = F/m.
<span>C) It does not change. At the point where the phase of a substance changes, there is no temperature change but only the phase change. After this, the temperature then goes up or down depending on the type of phase change occurring. </span>
Answer:
Explanation:
Speed is the distance covered over the time taken to do so.
s = d/t = 45 m / 3 s = 15 m/s
