Which of the following is the primary medium for beach erosion? ice gravity wind water

Answers

Answer 1

Answer: i believe it is water that is the medium for beach erosion

Answer 2

Answer: I think it would be water because the waves (tides) are repeatedly bringing sand to the shore and dragging more sand back into the ocean. So water seems the most logical.

What part of a wave best describes lowest point of a wave?A. the crest point
B. the wavelength
C. the center point
D. the trough point

Answers

Answer:

Option (D)

Explanation:

The transverse wave travels in the form of crests and troughs.

The highest point on the wave is called crest.

The lowest point on the wave is called trough.

The part of the wave that best describes lowest point of a wave is the trough (option D)

How do i determine the correct answer to the question?

To know the correct answer to the question, we shall define each option. This is shown below:

Crest of a wave is simply defined as the highest point or peak of a wave. It is the point on the wave propagation where the displacement is at its highest positive value.

Wavelength of a wave is the distance between two successive crest or trough of a wave propagation.

Center point of a wave is simply refer to the rest or equilibrium point of the wave

Trough of a wave is simply the defined as the lowest point of the wave, where the displacement of the wave is maximum in negative values.

With the above information in mind, we can conclude that the correct answer to the question is trough point (option D)

Gravity is greater when there is

Answers

when there is more mass and less distance between two objects

Gravity is greater when there is more mass and less distance between two given objects.

Material speed of lightspace 3 x 108 m/s
water 2.25 x 108 m/s
glass 2 x 108 m/s
air 3 x 108 m/s

Light moves from air into a new material. The greatest refraction would occur when light passes through which material?
A) air
B) glass
C) water
D) It would refract the same amount in each material.

Answers

The question is poor. Light doesn't refract on its way THROUGH anything. It refracts at the boundary BETWEEN two different media. The effect is greatest where the ratio of the speeds of light in the two media is greatest. On your list, that would be at the boundary between air or space and glass.

Answer: I think the answer is B glass.

Explanation: Because Glass is light.

In the Bohr model of the hydrogen atom, an electron moves in a circular path around a proton. The speed of the electron is approximately 2.03 106 m/s.(a) Find the force acting on the electron as it revolves in a circular orbit of radius 5.35 10-11 m.
whats the magnitude in N ?

(b) Find the centripetal acceleration of the electron.
whats the magnitude in m/s2

Answers

In order to answer these questions, we need to know the charges on
the electron and proton, and then we need to know the electron's mass.
I'm beginning to get the creepy feeling that, in return for the generous
5 points, you also want me to go and look these up so I can use them
in calculations ... go and collect my own straw to make the bricks with,
as it were.

Ok, Rameses:

Elementary charge . . . . . 1.6 x 10⁻¹⁹ coulomb
negative on the electron
plussitive on the proton

Electron rest-mass . . . . . 9.11 x 10⁻³¹ kg

a). The force between two charges is

F = (9 x 10⁹) Q₁ Q₂ / R²

= (9 x 10⁹ m/farad) (-1.6 x 10⁻¹⁹C) (1.6 x 10⁻¹⁹C) / (5.35 x 10⁻¹¹m)²

      = ( -2.304 x 10⁻²⁸) / (5.35 x 10⁻¹¹)²

=    8.05 x 10⁻⁸ Newton .

b). Centripetal acceleration =

   v² / r .

A = (2.03 x 10⁶)² / (5.35 x 10⁻¹¹)

   =    7.7 x 10²² m/s² .

That's an enormous acceleration ... about 7.85 x 10²¹ G's !
More than enough to cause the poor electron to lose its lunch.

It would be so easy to check this work of mine ...
First I calculated the force, then I calculated the centripetal acceleration.
I didn't use either answer to find the other one, and I didn't use " F = MA "
either.

I could just take the ' F ' that I found, and the 'A' that I found, and the
electron mass that I looked up, and mash the numbers together to see
whether F = M A .

I'm going to leave that step for you.   Good luck !

Earth is the only planet known to have _____.an atmosphere
a lithosphere
a biosphere
a cryosphere

Answers

the answer is bioshere

Answer:

A biosphere

Explanation:

Biosphere refers to the zone of life on a planet. It includes all living elements of a planet. It is also known as Eco-sphere and includes the interaction of all living being with their surrounding.

Of all the planets and exo-planets, Earth is the planet known to have life and thus biosphere.

Whereas atmosphere, lithosphere and cryosphere can be found on other planets as well.

Atmosphere: Layer of air and gases surrounding a planet or any celestial object. (Except Mercury, all the planets of solar system have atmosphere)

Lithosphere: it refers to the rigid outer part of the planet which includes crust and mantle. (All the rocky planets have lithosphere)

Cryosphere: portion of the planets where water is in ice form. (Many exoplanets have been discovered having cryosphere)
