Balanced Forces =》 If the resultant of several forces acting on a body is zero, the forces are said to be Balanced Forces.
Or
When two forces of equal magnitudes but acting in opposite direction on an object simultaneously then the object continuous in its state of rest all uniform motion in a straight line such forces acting on the object are known as Balanced Forces.
Unbalance Forces =》 If the resultant of several forces acting on a body is not zero, the forces are said to be Unbalanced Forces.
Or
When two forces of unequal magnitudes act in opposite direction on an object simultaneously then object moves in the direction of the force with larger magnitude forces. These force acting on the object are known as Unbalanced Forces.

Hope this helps . . . . ..c
..... equal to the force from the engine pushing the car forward.
That's why the car is not accelerating. The horizontal forces on it
are balanced.
Answer:
350.72 m/s
Explanation:
Formula for velocity of wave is;
v = fλ
Where;
v is speed
f is frequency
λ is wavelength
We are given;
f = 512 Hz
λ = 0.685 m
Thus;
v = 512 × 0.685
v = 350.72 m/s
I will not help you but i would surely take these points for answering this question but i lied.
