<u>Answer:</u> The correct answer is two electrons are shared between each hydrogen atom and the carbon atom bonded to it, and four electrons are shared between the carbon atoms.
<u>Explanation:</u>
Ethylene is a compound given by the chemical formula
.
The bond present between hydrogen and carbon atoms or carbon and carbon atoms are covalent bonds. A covalent bond is formed by the sharing of electrons between the atoms combining.
A double bond is present between carbon and carbon atoms. So 2 pairs of electrons are shared which means in total of 4 electrons are shared.
Bond present between hydrogen and carbon atoms are single bonds. So, a pair of electrons is shared which means that in total of 2 electrons are shared.
Hence, the correct answer is two electrons are shared between each hydrogen atom and the carbon atom bonded to it, and four electrons are shared between the carbon atoms.
Newton's Third Law is every action has an equal and opposite reaction.
B. 200 N Backwards is the correct answer
The ball should put 200 N of force towards the golfer.
The ball is exerting 200 N of force towards the club as well, but the opposite reaction is that it flies away.
For more details: For each reaction there must be a opposite reaction(Which is the ball going 200 N backwards) and an equal reaction(The ball putting 200 N of force towards the golfer and the golfer)
It doesn't matter what the velocity is, or for how long.
They could both be anything.
"Constant velocity" means <em>zero</em> acceleration.
