Answer:
3.75s
Explanation:
a = 8.0 m/s V = 30 m/s U = 0 m/s t = ?
t = V - U/a
t = 30 - 0/8
t = 30/8 = 15/4
t = 3.75s
D because choppy water is already a little bit of wave action and then the wind adds a lot of speed to the waves and height to the waves to meek the best waves. Hope this helped.
The two kinds of motion are horizontal and vertical

Answer:
9 x 10^-12 c
Explanation:
q1 = 6 C
d = 0.3 m
q2 = ?
F = 5.4 N
As te force on the second charge is in the positive X axis direction so the charge on the second particle is positive in nature.
F = K q1 q2 / d^2
5.4 = ( 9 x 10^9 x 6 x q2) / (0.3 x 0.3)
5.4 x 0.3 x 0.3 = 54 x 10^9 x q2
q2 = 9 x 10^-12 C
