Answer:
standing wave, also called stationary wave, combination of two waves moving in opposite directions, each having the same amplitude and frequency.
For oppositely moving waves, interference produces an oscillating wave fixed in space. fixed nodes in a standing wave. Location of fixed nodes in a standing wave
these are the points that undergo the maximum displacement during each vibrational cycle of the standing wave. In a sense, these points are the opposite of nodes, and so they are called antinodes. A standing wave pattern always consists of an alternating pattern of nodes and antinodes
Explanation:
Answer: The correct answer is balanced force.
Explanation:
Balanced forces are balanced when the forces are acting equal in magnitude but opposite in direction. The balanced forces will not cause change in the speed of the object.
Unbalanced forces are unbalanced when the forces acting on the object are not equal in magnitude. The combined force is the difference between the forces. It will cause the change in the speed of the body.
Therefore, forces that are equal in size but opposite in direction are balanced.
Yup the correct answer is A jus finished the quiz :)
hope i helped^_^
Answer:
What is a Free Body Diagram?
The free body diagram helps you understand and solve static and dynamic problem involving forces. It is a diagram including all forces acting on a given object without the other object in the system. You need to first understand all the forces acting on the object and then represent these force by arrows in the direction of the force to be drawn.

Answer:
Explanation:
As a ball dropped into a river, its initial velocity is zero and then it is moving under the acceleration due to gravity. That means the acceleration on the ball is in vertically downwards direction which is equal to the acceleration due to gravity that means - 9.8 m/s^2.
When a bullet is fired from a gun straight downwards direction, the acceleration on the bullet is again acceleration due to gravity and it is acting acting downwards. In this case the initial velocity os not zero but acceleration is - 9.8 m/s^2.
