The reason why a stretched string is not a line because it's consists of two finite points. Point "A" and Point "B'. While having two points defines a line, a string is only as finite as it's length. A true line is infinite.
If your hand holds a string and stretches it, you've actually made a line segment because it has two end points and does not extend infinitely in either direction (it ends at your fingers or points).
do it yourself, think !
explain the differences between a point and a line and a plant
Points that are collinear will be located on the same line. A line is a subset of a plane. Therefore, Yes, points that are collinear will be located on the same plane.
No, it can only have one midpoint, because if it had two midpoints, then there would be two line segments! Also, if you add two midpoints, then thus creating another segment.
You can find the perimeter of any planar (flat) object using string by wrapping the string around the outside of the object, noting the point on the string where you return to the starting point, and then measuring the length of that portion of the string.
a line is a set of infinite points. a stretched string is finite.
When a stretched string is released, the potential energy in the string is converted to kinetic energy, causing the string to vibrate due to the release of stored energy.
Elastic potential energy is stored in a stretched string, which is the energy stored in an object when it is deformed (such as being stretched) and can be released when the object returns to its original shape.
kinetic energy
The tension in the string would increase as it is being stretched, causing the string to become tighter. The frequency at which the string vibrates would also increase, resulting in a higher pitch when plucked.
Kinetic energy and then to heat.
A transverse wave can be produced on a stretched string. In this type of wave, the motion of the particles of the medium is perpendicular to the direction of the wave propagation.
When a stretched string is released, the potential energy stored in the string is converted into kinetic energy as the string vibrates. This kinetic energy causes the string to oscillate back and forth until the energy is dissipated as sound waves.
In reality 3, since it will always have a thickless - no matter how small. However, it may be approximated by a 1-dimensional line segment.
the wave produced in a stretched string will be a standing wave .it will have a node and antinode.node means point with zero displacement and antinode means point with maximum displacement

The law of vibrating strings is the vibrational mode of a string that is stretched. The wavelength is twice the length of the string.
