A segment of a circle is known as an arc.A segment of a circle is called a arc.A segment of a circle is known as an arc.
if that line segment intersects the centre of the circle it is called a radius.
meridian
Whichever segment it is to which you are referring, it does not need to be red; it can be any color.The segment that intersects both foci is called the semi-major axis. The segment that is perpendicular to the semi-major axis with one end midway between the foci is called the semi-minor axis.
midpoint
The circular muscle layer prevents food from traveling backward and the longitudinal layer shortens the tract. By Ah Mok
adduction
If the particles of the medium vibrate in the direction of propagation of wave, as in sound waves that's why sound waves are called longitudinal waves.
This is a longitudinal wave or a P-wave (primary wave), called so because it travels faster than a transverse wave, which moves at right angles to the direction the wave travels.
osteonic canals
It is called rotation.
Longitudinal wave. (as opposed to Transverse waves, where the vibrations are perpendicular to the direction of movement.)
monovloement
MOTION
a wave in which matter is moved back and forth in the direction the wave is moving
It would be called a revolution.
This type of wave is called longitudinal waves.
