The return of a wave back to its original medium is called an reflection
Initial velocity(u) = 11.2 m/s.
Final velocity(v) = ?
acceleration(a) = 10.2 m/s²
Using kinematic equation v = u + at
v = 11.2 + 10 x 8 = 11.2 + 80 = 91.2 m/s.
Therefore final velocity is 91.2 m/s.
Answer:First the Republicans were dominant from 1860 to around 1882, then not again until 1920 time 1932. The reason for the first part is the Democratic party started a civil war to keep their slaves and the Democratic party lost that war.

This is what i found.
Answer:
<h2>4.9 J</h2>
Explanation:
The gravitational potential energy of a body can be found by using the formula
GPE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have
GPE = 10 × 9.8 × 0.05
We have the final answer as
<h3>4.9 J</h3>
Hope this helps you
Explanation:
It is given that,
Speed, v₁ = 7.7 m/s
We need to find the velocity after it has risen 1 meter above the lowest point. Let it is given by v₂. Using the conservation of energy as :
So, the velocity after it has risen 1 meter above the lowest point is 6.26 m/s. Hence, this is the required solution.
