Answer:
The opposite wave of same frequency...
Explanation:
Let us take an example. We know the noise cancellation property of most of the modern headphones. When sounds from the environment is picked up by the microphone embed into the headphones, a opposite wave of same frequency is transmitted out that interact destructively and causes destructive interference and cancel out each other in this process.
The boat will move -0.24 m and the negative sign indicates left direction.
<u>Explanation</u>:
mass of people A = 78 kg
mass of people B = 59 kg
mass of rowboat = 88 kg
Let the displacement of the boat be x
![x_{B,G} = x](https://tex.z-dn.net/?f=x_%7BB%2CG%7D%20%3D%20x)
= 2.9 + x
![x_{B,G} = x_{B,Boat} + x_{B,G}](https://tex.z-dn.net/?f=x_%7BB%2CG%7D%20%3D%20x_%7BB%2CBoat%7D%20%2B%20x_%7BB%2CG%7D)
= -2.9 + x
As net external F = 0
∑mx = 0
88 (x) + 78 (2.9 + x ) + 59 (-2.9 + x) = 0
88x + 226.2 + 78x - 171.1 + 59x = 0
225x + 55.1 = 0
x = -55.1 / 225
x = -0.24
The negative sign indicates left direction.
