<h2>Answer: Medium
</h2>
The medium is the main factor that differentiates a mechanical wave from an electromagnetic wave, since the first can not propagate without its existence, while the second can propagate regardless of whether the medium exists or not.
In addition, it is the medium that will define, the propagation speed of the wave, according to its specific physical characteristics.
Therefore, the <u>correct answer</u> is a.
Answer:
V = 0.074 m/s
Explanation:
given,
mass of the receiver, M = 96 Kg
mass of the ball, m = 0.42 Kg
initial speed of the ball, v = 17 m/s
initial speed of the receiver = 0 m/s
final speed.V = ?
using conservation of momentum
M u + m v = (M + m) V
0 + 0.42 x 17 = (96+0.42) V
96.42 V = 7.14
V = 0.074 m/s
hence, Speed after catching the ball is equal to 0.074 m/s
