A long string carries the wave; a segment of the string measuring 6.00 meters in length and weighing 180 grams contains four full wavelengths. The string vibrates sinusoidally at a 50.0 Hz frequency with a 15.0 cm peak-to-valley displacement. The vertical distance between the farthest positive and negative positions is known as the "peak-to-valley" distance. The function that describes this wave traveling in the positive x direction is .
If phase constant is then
equation is
∴ equation is
- A wave is a disturbance that moves from one location to another, carrying energy but not always matter.
- The square of the equation provides a probability density map of the locations where an electron has a specific statistical likelihood to be at any given moment in time. Wave functions have no direct physical meaning.

I think you're fishing for "temporary magnet" or something like that,
but I don't agree with it.
Credit card strips, refrigerator magnets, recording tape, bar magnets,
and big heavy horseshoe magnets are permanent magnets ... you don't
have to keep an electric current circulating around them to make them
magnetic.
But that doesn't mean that they stay magnetic no matter WHAT you do
to them. They can be DEmagnetized by being heated, dropped on the
floor, hit with a hammer, or in the presence of another, stronger magnet.
Answer: A) kilograms
Explanation:
The amount of matter in a body is defined as mass, which is a physical quantity that expresses the measure of inertia of a body, determined by the acceleration produced when a force acts on it.
The unit of mass in the International System of Units (SI) is the <u><em>kilogram</em></u>, which was defined for many years from a standard object (the international prototype of the kilogram located at the International Office of Weights and Measures). However, since of May 20, 2019, its definition became linked to Planck's constant
