When the magnitude of all opposing forces is equal, then the force is called balanced. The forces on W and Y are balanced while the forces on X and Z are unbalanced.
<h2>
Net Force:</h2>
It is defined as the vector sum of all forces acting on the object. The forces with the same magnitude in the opposite direction cancel each other.
<h3>Balanced force: </h3>
When the magnitude of all opposing forces is equal, then the force is called balanced.
<h3>Unbalanced force: </h3>
When a force is more than the opposing force, the force is called unbalanced.
Therefore, the forces on W and Y are balanced while the forces on X and Z are unbalanced.

Answer: The different speed of sound waves in water and in air
Explanation:
In general, sound (which is a mechanical wave) travels faster in solids than in liquids or gases. This is because the speed of mechanical waves is determined by a relationship between the elastic properties of the medium in which they are propagated and the mass per unit volume of the medium (that is: density).
In other words: The speed of sound varies depending on the medium through which the sound waves travel.
This is why Jason notices that sounds underwater (a liquid medium) are different from sounds above water (a gas medium: air).
Answer:
The purpose of our major is to deepen knowledge and understanding of one of the most powerful forces operating on people, communities and corporations today, namely government and politics in the USA and around the world. This knowledge and understanding is valuable for all citizens.

having into account that the total time spent in air till the cap came to her hands is Ttotal=2*t
where t is the time which the cap spent to reach the heighest point or the maximun height. so;
Ttotal=2second
t=1sec
we then replace t into the equation(1);
this is the initial velocity with which the cap was thrown
