Answer:
-4.5 m/s
Explanation:
Even without doing calculations, we know that a projectile has the same speed coming down as it did going up at the same height. Since it went up at 4.5 m/s, it returns down at -4.5 m/s.
To prove it with math, use the given information:
v₀ = 4.5 m/s
a = -9.8 m/s²
Δy = 0 m
Find: v
v² = v₀² + 2aΔy
v² = (4.5 m/s)² + 2 (-9.8 m/s²) (0 m)
v = -4.5 m/s
Is this your Question:
Read the hypothetical situation below and answer the question that follows.
In response to criticisms that the King of Mordor has failed to gain the consent of his people, the King claims that he does in fact represent the consent of the people because without their King, society would crumble into chaos.
Which statement BEST represents a rebuttal that Rousseau would use to counter the King's argument?
A.
Absolute chaos is preferable to the absolute power of the King.
B.
The King of Mordor should establish a system of checks and balances.
C.
If the King of Mordor were to represent the will of his people, then he would at least provide the public services demanded by his people.
D.
It is impossible for the King of Mordor to have the consent of the people because the monarchy is not a freely formed government in which the people have a say in how it operates.
If this is your question.. Here is your Answer:
Answer: D.
It is impossible for the King of Mordor to have the consent of the people because the monarchy is not a freely formed government in which the people have a say in how it operates.
Explanation:
Rousseau believed that sovereignty (the power to make laws) belonged to the people, not one person, and that it should be carried out by a representative body of the people who are elected by them on their behalf. While he agreed society requires a ruler(s), he thinks they should be chosen by the people.

The percent ionization of the acid is 44.56%
<h3>How can we calculate the percent ionization of the acid?</h3>
To calculate the percent ionization of the acid we are using the formula,
The H⁺ ion concentration [H⁺] = C x,
where, we are given,
C= concentration of the acid.
=0.39 M
x= degree of dissociation of the acid.
And one more thing we are given that, the pH of the acid=0.76.
So from the above statement we can say that,
pH = - log [H⁺]
Or,0.76 = -log [H⁺]
Or, log [H⁺] = -0.76
Or, [H⁺] = antilog -0.76
Or,[H⁺]= 10^-0.76
Or,[H⁺]=0.1738.
Now from the above calculation we know, the H⁺ ion concentration= 0.1738 M.
Now we put the known values in the above equation,
[H+]= Cx
Or,0.1739= 0.39 x
Or, x= 0.4459
From the above calculation we can conclude that the percent Ionization of the acid= 0.4459 X 100= 44.59%≈45%
