What are waves?A wave is a dynamic disturbance that propagates and causes a change in equilibrium of one or more parameters in physics, mathematics, and related subjects. Quantities may oscillate regularly around an equilibrium (resting) value at certain frequency if a wave is periodic. A traveling wave is one in which the entire waveform moves in one direction; in contrast, a standing wave is one in which two periodic waves are overlaid and move in the opposing directions. In a standing wave, there are some points where the wave amplitude seems reduced or even zero, and these positions have null vibration amplitudes.What materials make up a wave?Water moves in a circular motion as a result of energy traveling through it, creating waves. Water does not, however, literally move in waves. In the ocean, waves carry energy rather than water, and if there is nothing in their path, they have the capacity to cross an entire ocean basin.Learn more about wave here:

can be used to find the x-coordinate of the point.
can be used to find the y-coordinate of the point.
(–7 – 3) + 3 can be used to find the x-coordinate of the point.
(–6 – 1) – 1 can be used to find the y-coordinate of the point.
– 1 can be used to find the y-coordinate of the point.
Answer:
To determine the midpoint of a line segment with the given endpoints, one should determine the averages of the coordinates of the points.
x-coordinate: (3 + -7) / 2 = -2
y-coordinate: (-1 + -6) /2 = -7/2
Hence, the coordinates of the midpoint of the line segment are (-2, -7/2).

This process is the product of convection. Convection is the spontaneous movement of a single or multiphase fluid caused by the combined effects of material property heterogeneity and body forces on a fluid, most often density and gravity. Heat is transferred through convection, which is the large-scale movement of molecules inside gases and liquids.
Conduction is used to move heat from the object to the fluid initially. When the cause of the convection is unknown, convection caused by thermal expansion and buoyancy might be assumed. Convection can also occur in soft substances or mixes in which particles can flow. Convective fluid can be transitory or steady state .
