No - a piece of string can be any length you like.
If the wire is stretched it must mean that both ends are attached to something and are not free to move. As such a condition on any possible oscillation is that the end points remain stationary. If it is also a standing wave the first harmonic is formed by the oscillation which has only two stationary points (the ends). Only half of one wavelength fits on the wire therefore the wavelength of the first harmonic is twice 2.3 meters equaling 4.6 meters.
It is most impossible to pour water down a string unless the string is not a string and is a tube. water can only go down hollow things for heaven's sake!
No. Only the length of the string and the value of g does.
Only if you rub it on a piece of cloth.
No, the force in tension of a string is not conservative. The only non-conservative force acting is the tension force, but it acts perpendicular to the path of the object at every instant, and so it does zero work.
Only if it happens to be a 2 foot long piece of string.
Diameter is not a unit of length and so the only appropriate answer is, perhaps, "As long as the piece of string!"
piece of string
You actually only need one piece of string to string a racquet. The string has to be about 10m long though! it all depends on what you are looking for from the string. The most you should use though is two, one for the main strings (lengthways) and one for the crosses.
I would say that this is akin to how long is a piece of string. At the end of the day it is only limited by the imagination of people!
the boat weren't long there only 5 meters
Sqm (or square meters as they are known) are a measure of area. You use it to show the size of a room or a plot of land. When something is 2000 square meters, it could be a piece of land that is 1 meter wide and 2000 meters long, or 20 meters wide and 100 meters long. Since an area only indicates the size of a plot of land or a room and not the shape, you can't convert it to meters. Remember: you can't convert a value that indicates area to a value that indicates length.
That depends on the species of rhino. The largest rhino, the white rhino, is 3.4 meters to 4 meters long. The smallest rhino, the Sumatran rhino, is only 2.36 to 3.18 meters long.
You'd have to string 304,800,000 of them together end-to-end to stretch one foot long. If you only wanted the string to go one inch, you'd only need 25,400,000 of them.
It depends, all of them are different, but only by a little. Average, they are about 120 meters long, and 80 meters wide.
If the string is long enough and the cubes are strung through one corner only.
The largest rhino is the white rhino. It is up to 4 meters long and 1.9 meters tall at the shoulder. The smallest is the Sumatran rhino, which is only 1.5 meters tall and 2.4 to 3.2 meters long.
