A) the waves can grander energy through solid,liquid, and gases
C) the waves transfer energy by causing particles of matter to move.
D) the waves need to master to transfer energy
Answer:
The experiments are not shown, so I will answer in a general way.
By the first Newton's law, an object will only change it's velocity if there is a net force different than zero acting on the object.
Then in the experiments (depending on the experiment), you can see different things.
If an object is not moving and you apply a force in it, the object will move.
If an object is moving and you apply a force in the opposite direction of it's motion, the motion will: decrease the speed, stop at all, or move in the opposite direction. Depending on the force that you apply.
An excellent experiment (but hard to do) is dropping an object from a really high place.
The gravitational force will pull down the object and the object will start to increase it's velocity.
But there is the air resistance, that opposes to this motion and increases with the speed of the object.
Then there is a given speed such that the air resistance force will be equal to the gravitational force, then we have a balanced force (the net force is zero) which means that the object will keep falling at a constant velocity.
