In a periodic table a set of properties repeats from row to row
Explanation;
In a periodic table, a set of properties repeats from row to row. This is called the periodic law. In the periodic table, the rows are called periods and the columns are called groups.
The modern periodic table is organized by increasing atomic number. The atomic mass unit is based on 1/12th the mass of a carbon-12 atom.
The atomic mass of an element is the weighted average of the masses of an element’s isotopes.
Force = mass * acceleration
mass = Force/acceleration
= 36/2
mass = 18 kg
Answer:
The gravitational force between them quadruples
Explanation:
According to law of gravitation, the force of attraction (F) between two masses m1 and m2 is directly proportional to the product of the masses and inversely proportional to the square of the distance(r) between them. Mathematically,
F1 = Gm1m2/r²... 1
If their masses doubles, the formula becomes;
F2 = G(2m1)(2m2)/r²
F2 = 4Gm1m2/r² ... 2
Dividing equation 2 by 1, we have;
F2/F1 = {4Gm1m2/r²}÷{Gm1m2/r²}
F2/F1 = 4Gm1m2/r²×r²/Gm1m2
F2/F1 = 4
F2 = 4F1
The gravitational force between the masses when they doubles quadruples.
