Answer:The source of all wave motion is a disturbance in matter or a vibration. Think about a water wave.
Explanation:
<u>Answer</u>
1.26 rad/s
the first step is to find the frequency of the wheel.
The wheel rotates at rate of 5 revolutions in 25 seconds. The frequency is the number of revolutions per second.
frequency (f) = 5/25
= 1/5
= 0.2 Hz
Angular velocity = 2πf
= 2×π×0.2
= 0.4π rad/s or
= 1.26 rad/s
The rate of change of velocity
The answer would be, "Granite".
Answer:
increasing the masses of the objects and increasing the distance between the objects
