Yes, that is correct. This noise cancellation mainly works for lower frequencies, and is somewhat limited for higher frequencies.
Yes, sound waves can be cancelled out using equal but opposite sound waves through a process called destructive interference. When two sound waves with identical frequencies and amplitudes but opposite phases meet, they can interfere and cancel each other out, resulting in a decrease in overall sound intensity at that location.
The net force on the object will be zero because the forces cancel each other out.
Their magnitudes are exactly equal and their directions are exactly opposite.
The electric field strength exactly midway between two equal charges is zero. This occurs because the electric fields produced by the two charges cancel each other out at that point due to their opposite directions.
If two forces cancel each other out, their magnitudes must be equal and opposite in direction. This means that the size of each force is the same but they act in opposite directions, resulting in a net force of zero.
They are headphones specially designed to cancel out noise in your surrounding area so that all you hear is the music you are listening to. There is no price difference between them and other headphones
Opposite of you
I do not know if it's exactly 'opposite' but Bicycle springs to mind

They is actually not any antonym for the word kneel, because they is not word that means exactly the opposite as the word kneel.
The neck does not exactly have an opposite, but in some circumstances we might contrast it with the body.
A rectangle is a parallelogram, and neither a trapezoid nor an isosceles trapezoid could have exactly two opposite right angles.So, a quadrilateral that is not a parallelogram and could have exactly two opposite right angles must be a kite.
Their magnitudes are exactly equal, and their directions are exactly opposite.
Klipsch s5i kinda up there in price but exactly what you're looking for
If it's the hoodie buddie then turn it inside out. If its not just put the headphones on the inside of the jacket if possible. Then wash. If the Jacket has Headphones they are meant to be water proof.
This isn't exactly the correct answer, but you can plug your headphones into where your microphone would be plugged in at (As long as it isn't headphones that plug into an USB port) and they would work as a microphone. (Download audacity if you want a good test of this.)
What exactly do you mean when you say "the opposite of a whole number" . . .
