Because sounds are made up of waves of compressed and decompressed air, and when two waves meet that are exactly out of phase, or opposite each other, then the total sound produced is zero. See "sound cancellation" in the link below.

I believe the best answer for you would be the 18th andthe 21st amendments would be what you are looking for. They refer the the beginning, and the later repeal, of prohibition.

When sounds overlap, they can create interference patterns known as interference or inharmonicity. This can result in a phenomenon called constructive interference, where the sounds reinforce each other, or destructive interference, where the sounds cancel each other out. The interference can change the overall quality and perceived loudness of the sounds.
When two sounds are exactly out of phase and have the same amplitude, they undergo destructive interference, causing them to cancel each other out. This occurs when the peaks of one sound wave align with the troughs of the other, resulting in a reduction or complete elimination of sound.
Never, they always cancel each other
Complementary colors cancel each other out in the color wheel.
They do not cancel each other out. Each serves a different purpose in cooking and baking.
Balanced forces, that are of equal strength.
Forces that cancel each other out are called balanced forces.
They react and cancel each other out. The process is called neutralization and it causes them to cancel out.
If they cancel, then their magnitudes must be equal.
Forces that don't cancel each other out are called unbalanced forces. When two or more forces act in opposite directions and do not cancel each other completely, they create a net force that results in an acceleration of the object.
They do not cancel each other out but there is evidence that lansoprazole (Prevacid) may decrease the effectiveness of clopidogrel (Plavix).
no, calories and a treadmill do not cancel each other. Calories are burned by excercising. If you eat more calories than you burn, you will most likely lose weight. If you eat more than you burn, you will gain weight. They dont cancel each other, but a treadmill can be an effective way to burn calories and in essence "cancel" the calories
