The correct answer is:
<span>Point charges must be in a vacuum.
In fact, the usual form for of the Coulomb's law is:
</span>
<span>where
</span>
is the permittivity of free space
<span>q1 and q2 are the two charges
q is the separation between the two charges
However, this formula is valid only if the charges are in vacuum. If they are in a material medium, the law is modified as follows:
</span>
where
is the relative permittivity, which takes into account the dielectric effects of the material.
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.

The energy flow in the ecosystem is important to maintain an ecological balance. The producers synthesis food by the process of photosynthesis. A part of the energy is stored within the plants. The remaining energy is utilized by the plants in their growth and development.

Answer:15.20 m
Explanation:
Given
initial velocity 
inclined length=10 m
inclination 
So Particle launches with a speed of 5.31 m/s at an angle of \theta 
Total height raised is
