Answer:
Every object in space exerts a gravitational pull on every other
explanation : gravity influences the paths taken by everything traveling through space. It is the glue that holds together entire galaxies. It keeps planets in orbit. It can also cause life-destroying asteroids to crash into planets..
Answer:
Quick question do you mean what are some safety rules
Explanation:
Crosswalk, Stop sign,
The ions are able to carry electric current through a solution. Some liquids such as oil or alcohol do not form ions and do not conduct electricity. Vinegar is mostly water with a small amount of acetic acid in it. The acetic acid separates into ions on so that the solution conducts electricity. BRAINLIST ME PEASE

Explanation:
The charge on each of the equally charged drops of hairspray willl be 7 × 10 ⁻¹³ C
<h3>What is Columb's law?</h3>
The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Similar charges repel each other, whereas charges that are opposed attract each other.
Given data;
Electric force,F = 9 × 10 ⁻⁹ N
Distance between charges,d = 7 × 10⁻⁴ m
Chrge,q₁ = q₂ =q C
From Columb's law;
![\rm F = K \frac{q_1q_2}{d^2} \\\\ 9 \times 10^{-9} = 9 \times 10^9 \frac{q^2}{(7 \times 10^{-4})^2} \\\\ q^2 = 4.9 \times 10^{-25} \\\\ q = 7 \times 10^{-13} \ C](https://tex.z-dn.net/?f=%5Crm%20F%20%3D%20K%20%5Cfrac%7Bq_1q_2%7D%7Bd%5E2%7D%20%5C%5C%5C%5C%209%20%5Ctimes%2010%5E%7B-9%7D%20%20%3D%209%20%5Ctimes%2010%5E9%20%5Cfrac%7Bq%5E2%7D%7B%287%20%5Ctimes%2010%5E%7B-4%7D%29%5E2%7D%20%5C%5C%5C%5C%20q%5E2%20%3D%204.9%20%5Ctimes%2010%5E%7B-25%7D%20%5C%5C%5C%5C%20%20q%20%3D%207%20%5Ctimes%2010%5E%7B-13%7D%20%5C%20C)
Hence the charge on each of the equally charged drops of hairspray willl be 7 × 10 ⁻¹³ C
