All waves must ____ have to travel through
</h2>
Explanation:
Wave
It is the periodic disturbance in a medium.
Types of Wave
There are two types of wave in general depending upon their propagation through a substance.
• Mechanical
• Electromagnetic
Mechanical Wave
It is the kind of wave which needs medium to travel. For example: Sound Wave
That means sound can be heard only whenever there is presence of certain substance like water, glass, air etc .It can’t be heard in vacuum no matter how loud is the sound.
Electromagnetic Wave
Is that which can travel through medium as well as through vacuum. For example: Light
But unlike sound, light can be seen through a substance or in vacuum. That is the reason it is referred as electromagnetic wave.
Calm, sunny days with wind moving away from the center.
Answer:
=6.5%
Explanation:
Mass of the ball: 
]
Initial velocity of the ball:
final velocity of the ball: 
which is -30/100 of =
Mass of the bottle: 
Initial velocity of the bottle: 
final velocity of the bottle: is unknown (to find)
<em>by using conservation momentum, which stated that the initial momentum is equal to the final momentum.</em>
<em />
<em />
<em>so since the bottle is at rest firstly, therefore </em>
<em />
<em />
<em />
<em />
<em> </em><em>equation 1</em>
so now substitute into equation 1
<em />
<em />
<em>collect the like terms</em>
divide both side by 
Now substitute
6.5%
<em />
Friction between the ball and the floor is stealing some of the kinetic energy of the ball, and turning it into heat.
