surface waves are caused primarily by what? question 6 options: frictional forces between wind and the ocean surface frictional forces at the level of the thermocline layer primarily gravitational forces of the moon large aquatic organisms breaching the ocean surface
Answers
Frictional forces between wind and the ocean surface are the primary cause of surface waves. This is the first option.
How are surface waves formed?The most common cause of waves is wind. Surface waves, also known as wind-driven waves, are formed by the frictional forces between wind and surface water. The continual disturbance creates a wave crest as wind blows across the surface of the ocean or a lake. Surface waves are found globally across the open ocean and along the coast.
There is also a type of waves called tidal waves. Tidal waves are caused by the gravitational pull of the Sun and Moon on Earth.

Answers
A total of 151988 sheets of paper are required to be put on the individual so that it create a pressure of 1 atm.
We know that the pressure is given by the force applied on the area divided by the magnitude of the area.
Here, it is given that dimensions of the paper is 8.5 inch X 11 inch.
So the area of the paper is 93.5 in².
Converting inch square into metre square,
Area = 0.06m².
The mass of 1 sheet of paper is 0.004 kg.
So the force applied by the sheet of paper on the person will be equal to,
F = 0.004 × 10
F = 0.04 N.
Let us say that n number of sheets are required.
The pressure that is needed to be created is 101325 pascals.
Now,
Pressure = force/area

Does surface tension push or pull?When the cohesive forces between the liquid molecules are greater than the adhesion to the walls, capillary action results.Water adhesion to a vessel's walls causes the liquid near the borders to be forced upward.The entire liquid surface is drawn upward because the surface tension maintains the surface in place. Surface tension exerts a force that is tangential to the surface, whereas air pressure exerts a force that is perpendicular to the surface.

a = 15m/s².
The acceleration of the rocket is 15m/s².
The force on an accelerated bodies given by,
F = Ma
M is the mass of the rocket,
Putting values,
300000 = M(15)
M = 20000 Kg.
So, the mass of the rocket is 20000 kg.

A dog pulls on a pillow with a force of 5.6 N at an angle of 39 degrees above the horizontal. Assume the x-axis of a reference frame is along the horizontal and the y-axis is along the vertical. Find the x and y components of the force.
Answers
1. The x component of the force is 4.4 N
2. The y component of the force is 3.5 N
How do I determine the components of the force?The following data were obtained from the question:
Force applied (F) = 5.6 NAngle (θ) = 39 degreesx component =?y component =?1. How to determine the x component
Force applied (F) = 5.6 NAngle (θ) = 39 degreesx component =?x component = FCosθ
x component = 5.6 × Cos 39
x component = 4.4 N
2. How to determine the y component
Force applied (F) = 5.6 NAngle (θ) = 39 degreesy component =?y component = FSineθ
y component = 5.6 × Sine 39
y component = 3.5 N
