Answer:
<h3>The answer is 45 kg • m/s</h3>
Explanation:
The momentum of an object can be found by using the formula
<h3>momentum = mass × velocity</h3>
From the question
mass = 15 kg
velocity = 3 m/s
We have
mass = 15 × 3
We have the final answer as
<h3>45 kg • m/s</h3>
Hope this helps you
Explanation:
The displacement of the string in the x direction is given by :

Where
A is the amplitude of wave
k is the propagation constant
1. Here, the phase of the wave is 
2. The propagation constant of a wave is given by :


3. Since, 

Time period, 

4. Speed of this wave is given by :



Hence, this is the required solution.
The answer is b) control variable
