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%

Answer:
Explanation:
I-V graph always represent a straight line
Yes, C is correct. It self explains itself as we know light travels through a vacuum ( doesn't need a medium) and light is a type of electromagnetic wave.
Answer:
4.8 mph
Explanation:
From the question,
Average speed = total distance/total time
V = d/t....................... Equation 1
Where d = distance, t = time
Given: d = 26.2 miles, t = 5.5 hours.
Substitute these values into equation 1
V = 26.2/5.5
V = 4.76 mph
V ≈ 4.8 mph
B .Newton's first law holds that your body moves along with Earth because it is not compelled to change its motion by an unbalanced force
