Where is oceanic crust being formed?
Sever21 [200]
Oceanic crust is being formed it is because of the tectonic plates. Tectonic plates work because of volcanic eruption every time it will erupt the tectonic plates underground will have more pressure on magma, then below there will be a volcano thats why their is a volcano in ocean. The heat rises up then it will open, thats what we call divergent bounderies then their will be earthquakes form. Then another plate opens up and the crust is going down, it will stop if the volcano stops erupting because there is more lava left in volcano then it will go underwater and thats why oceanic crust is being formed.

Electrons are ejected from sodium metal by any light that has a wavelength shorter than 544 nm. What is the kinetic energy of an
wel

Answer:

KE=2.3 x 10⁻¹⁹ J

Explanation:

Given that

λ = 544 nm

λ' = 485 nm

The kinetic energy KE given as

KE= E - Ф

Where

E=\dfrac{hC}{\lambda'}

\phi=\dfrac{hC}{\lambda}

h= 6.626 x 10⁻³⁴

C=3 x 10⁸ m/s

Now by putting the values

KE=\dfrac{hC}{\lambda'}-\dfrac{hC}{\lambda}

KE=\dfrac{34.34\times 10^{-34}\times 3\times 10^8}{485\times 10^{-9}}- \dfrac{34.34\times 10^{-34}\times 3\times 10^8}{544\times 10^{-9}}

KE=2.3 x 10⁻¹⁹ J

This is kinetic energy.

If the speed of light is 1.5times that of the speed of light in a given material what is the index of refraction for that materi
jok3333 [9.3K]
The answer is 1.5....
The refractive index n = (Speed of light, c) /( Speed of light, v)
So c= n x v
comparing to c= 1.5 x v in this situation we see that n= 1.5

Toy car W travels across a horizontal surface with an acceleration of aw after starting from rest. Toy car Z travels across the
tamaranim1 [39]

Answer:

x = ½ aw t²

x = d − ½ az t²

Explanation:

The position of each car at time t is:

x = x₀ + v₀ t + ½ at²

For car W:

x = 0 + (0) t + ½ aw t²

x = ½ aw t²

For car Z:

x = d + (0) t + ½ (-az) t²

x = d − ½ az t²

Solving the system of equations for x will give us the location the cars meet (relative to car W's starting point).
