To choose the correct box plot, verify each of the options and make sure all the values in the plot match the values provided.
<h3>How to identify the median?</h3>
In a box plot, this value is represented by a vertical line located in the middle of the graph.
<h3>How to identify the maximum and the minimum?</h3>
The maximum is the value located on the farthest right, while the minimum is located on the farthest left.
<h3>How to identify the quartiles?</h3>
Divide the graph into 4 and analyze how much each quartile represents.

Answer:It increases confidence because the more times you conduct the same experiment over and over should either prove your hypothesis right and wrong and eliminate any random occurrences that might affect your results.

Explanation:
Answer:
Momentum is given by
p
=
m
v
. Impulse is the change of momentum,
I
=
Δ
p
and is also equal to force times time:
I
=
F
t
. Rearranging,
F
=
I

The change in momentum,

This is called the impulse:

=

p
. Impulse is also equal (check the units) to force times time:
I
=
F

We can rearrange this expression to make

The negative sign just means the force acting is in the opposite direction to the initial momentum.
(This will be the average force acting during the collision: collisions are chaotic so the force is unlikely to be constant.)
