NaHCO3
That is the formula for baking soda
I think it's A) Sunspots. I hope this helps:)
Direction of resultant force in circular motion is directed towards the center of the circle. Hence vector B is the direction of the resultant force.

Answer:
The value of new coulomb force is 1.43 N.
Explanation:
Given;
Coulomb's force in vacuum (air),
= 10 N
dielectric constant, K = 7
The Coulomb's force between two charges separated by a distance r in a vacuum is given as;

The Coulomb's force between two charges separated by a distance r in a medium with dielectric constant is given as

Take the ratio of the two forces;

Therefore, the value of new coulomb force is 1.43 N.
