Awave that moves back and forth at right angles is called what

A wave that moves back and forth at right angle is called Transverse waves. In transverse wave particles are in to fro motion perpendicular to the direction of energy.

if the forces acting on an object are unbalanced, the object will accelerate in the direction of the net force on the object.

explanation:

this is best explained by having an understanding of newton's second law, which states that f=ma. you see, when the forces are unbalanced, net force (sum of all forces) is not zero. therefore making it necessary for the object to have an acceleration in the direction of the net force.

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator
