!! HURRY PLEASE!!!!!
What is the relationship between wind and ocean waves?
A) Wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
B) Wind moving at higher speeds will transfer energy over a larger part of the ocean water, resulting in waves with a shorter wavelength.
C) Winds moving at higher speeds with cause water to move forward at faster rates, causing larger ocean waves.
D) Winds moving at higher speeds will affect deeper water, resulting in waves that move at a faster rate.

Answer:
Explanation:
The motion of the bullet is a uniformly accelerated motion, therefore we can find its acceleration by using the following suvat equation:
where
v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance covered
For the bullet in this problem:
u = 350 m/s is the initial velocity of the bullet
v = 0 is the final velocity (the bullet comes to a stop)
s = 0.125 m is the stopping distance of the bullet
Therefore, by solving the equation for a, we find its acceleration:
And the negative sign tells that the direction of the acceleration is opposite to that of the velocity.
Answer:
217.43298 m/s
Explanation:
= Mass of bullet = 19 g
= Mass of bob = 1.3 kg
L = Length of pendulum = 2.3 m
= Angle of deflection = 60°
u = Velocity of bullet
Combined velocity of bullet and bob is given by
As the momentum is conserved
The speed of the bullet is 217.43298 m/s
