Answer:
2. F g decreases to 1/9
Explanation:
The formula for calculating the Force of gravity between two masses separated by a distance is expressed as;
F = GMm/d² ... 1
If the distance is tripled, the new force will be;
F1 = GMm/(3d)²
F1 = GMm/9d² ... 2
Divide equation 1 by 2
F/F1 = GMm/d²÷GMm/9d²
F/F1 = GMm/d²×9d²/GMm
F/F1 = 1 * 9
F = 9F1
F1 = 1/9 F
<em>This means that the new force decreases to 1/9</em>

C) gain one electron.
Explanation:
A chloride ion forms when a chlorine atom gains an electron. An atom is made up of three fundamental particles which are:
- Protons which are the positively charged particles in an atom.
- Electrons which are the negatively charged particles in an atom.
- Neutrons do not carry any charges.
In a neutral atom, the number of protons and electrons are the same.
For an atom to become charged, it must gain or lose electrons.
- When an atom gains electrons, the number of protons is less than the number of electrons and it is negatively charged. Such an atom is called an anion.
- When an atom loses electrons, the number of protons is more and it becomes positively charged. Such an atom is called a cation.
A chlorine atom that has gained an electron is an anion. It is negatively charged.

Had to look for the options and here is my answer.
The statement that is considered correct regarding a wave that is propagating along the pavement and girders of a suspension bridge is this: "t<span>he wave is mechanical, with particles vibrating in a direction that is perpendicular to that of the wave, forming compressions and rarefactions." Hope this helps.</span>
