answer hope this helps and have a great day!!
Explanation:
If the two charges are point charges - i.e., they don't have a size - the force between these charges depends on the
• Magnitude if each charge, q1 and q2
• Sign of each charge (+ or -)
• Distance between the charges, r
This is essentially Coulomb’s Law:
FE = (kq1q2)/r2
For collections of charges, you need to find the electric field E, and then use this fields to find a force on a small test charge q in the field. The test charge is always small to help you map the electric field, but not disturb it.
If light is moving inside the glass, it will be reflected when the angle of incidence is above the critical angle of the material, which is given by
where
is the refractive index of air
is the refractive index of this type of glass
If we plug the numbers into the equation, we find
So, light will be reflected inside the glass when the angle is equal or greater than this value.
The movement of water that has the greatest effect on the growth of producers is <em><u>upwelling</u></em><em><u /></em>.
Upwelling is a rising of a liquid. The reason upwelling is much better for producers is because it is a slow rising in the water level, preventing erosion to the topsoil and still giving the necessary amount of water and nutrients the producers need.
Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if you need any more help with anything :D <span />
