Answer:
Third parties may also help voter turnout by bringing more people to the polls. Third party candidates at the top of the ticket can help to draw attention to other party candidates down the ballot, helping them to win local or state office.
The amplitude of the wave on the given sinusoidal wave graph is 10 cm.
<h3>
What is amplitude of wave?</h3>
The amplitude of a wave is the maximum displacement of a wave. This is the highest vertical position of the wave from the origin.
Amplitude of the wave is calculated as follows;
From the graph, the amplitude of the wave or maximum displacement of the wave is 10 cm.
Thus, the amplitude of the wave on the given sinusoidal wave graph is 10 cm.

Answer:
1.22375 m
Explanation:
v = Velocity = 4.9 m/s
g = Acceleration due to gravity = 9.81 m/s²
h = Height
In this system the kinetic and potential energy is conserved when Tarzan at the top of the swing
The height of the swing is 1.22375 m
As it can be seen in the equation the length of the vine does not matter
F_x=Fcos(a)
F_y=Fsin(a)
1.F_x=166cos(55)
F_y=166sin(55) (55 because of the supplementary angle)
2.F_x= 575cos(-75) (complimentary angle/negative because its under x-axis)
F_y= 575sin(-75)
The values you get can be negative or positive depending on which side the vector is pointing at.
KE = 1/2 * m* v^2
= 1/2 * 40 * 225
= 4500 J
