Answer:
A.) the inverse of the square of the distance separating them
Explanation:
Coulombs law states that "the force of attraction between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them."
Mathematically, F = kq1q2/r²
Where q1 and q2 are the charges
r is the distance between the charges.
According to the law, the force between two charged objects is related to the inverse of the square of the distance separating them.
Answer:
MASS
Explanation:
weight has to do with the gravitational pull, as distance from earth decreases, so does the gravitational pull. meaning, the size of the force, the pull, and the weight would all change. mass stays the same (in this sense. if you gain weight on earth you will gain mass as well, but if you leave earth your weight will lessen and your mass will stay the same.)
hope this helped.
Answer:
Explanation:
The volume of the tank = 50 kton
50 kton = 5 × 10⁷ kg
Since 18 grams of water will contain: 10 electrons × 6.023 × 10²³
Then;
5× 10⁷ kg will contain 
= 1.67 × 10³⁴ electrons
(b)
Suppose:

Then;
10⁻⁶ of 

Thus, the number of high energy neutrinos which will interact with water is:
= 
= 
= 
For 1.67 × 10³⁴ electrons, the detection rate is:


= 9.668 per day
Answer:
c
Explanation:
if numbers of protons and electrons are equal, the atom is neutral
