Vertebrate is the answer I think.
Answer: 
Explanation:
This problem is related to parabolic motion and can be solved by the following equations:
(1)
(2)
(3)
Where:
is the horizontal distance traveled by the golf ball
is the golf ball's initial velocity
is the angle (it was a horizontal shot)
is the time
is the final height of the ball
is the initial height of the ball
is the acceleration due gravity
is the final velocity of the ball
Let's begin by finding
from (2):
(4)
(5)
(6)
Substituting (6) in (1):
(7)
Finding
:
(8)
Substituting
in (3):
(9)
Finally:

Answer:
Doubled
Explanation:
F = 1.8 x 10^-6 N, q1 = q2
The force between the two charges is directly proportional to the product of two charges and inversely proportional to the square of distance between them.
Now one of the charge is doubled but the distance remains same so the force between the two charges becomes doubled.
According to the dictionary, amplitude is: "<span>the maximum extent of a vibration or oscillation, measured from the position of equilibrium."
Hope this helps, and happy studying~!
