<h3><u>Answer;</u></h3>
B) wind and tides.
<h3><u>Explanation;</u></h3>
- <u>Waves on the surface of the oceans occur as a result of energy passing through water. They are commonly caused by wind as a result of friction between wind and surface water.</u> As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.
- <em><u>Surface waves and currents may also be caused by the gravitational pull of the sun and the moon on earth.</u></em> Such waves caused by the gravitational pull of the sun and the moon are called tidal waves or tides.
<span>(a)
Taking the angle of the pitch, 37.5°, and the particle's initial velocity, 18.0 ms^-1, we get:
18.0*cos37.5 = v_x = 14.28 ms^-1, the projectile's horizontal component.
(b)
To much the same end do we derive the vertical component:
18.0*sin37.5 = v_y = 10.96 ms^-1
Which we then divide by acceleration, a_y, to derive the time till maximal displacement,
10.96/9.8 = 1.12 s
Finally, doubling this value should yield the particle's total time with r_y > 0

Answer:
The value is
Explanation:
From the question we are told that
The depth of the mountain is
Generally the velocity of the surface wave is mathematically represented as
=>
=>
Generally using the Froude number is mathematically represented as
Here V is the velocity of the current
Given that the waves do not travel upstream, then the flow of the current is supercritical which means that
=>
=>
Hence the minimum velocity of the current is
This because the velocity of the current is greater velocity of the surface wave , so minimum will be like the lowest possible value of V which is v
c. Wind power can turn turbines to generate electrical power.
Explanation:
The correct statement of all is that wind power can turn turbines to generate electrical power.
This is simply the way wind energy from waves are usually harnessed to produce electricity.
- When a metallic conductor passes in between magnetic fields, it induces and generates electricity as it turns.
- This is how electricity generating plants are fashioned.
- Geothermal energy is not generated from moving water. It is produced from heat within the earth brought to the surface. Power from moving water is hydroelectric power.
- Oil is a non-renewable resource
- Propane is a non-renewable resource
