(a) is a decomposition reaction
Answer:
True
Explanation:
All the planets have formed from a mass of spinning particles. As they formed from spinning mass the planets are still spinning due to the conservation of angular momentum. Hence all planets spins about an axis running through it.
All planets spin in counterclockwise direction when viewed from above. Except Venus rotates in anticlockwise direction and Uranus' axis of rotation is titled towards its side.
A hammer pounding a nail into a board is an example of Newton’s Third law.
Newton’s third law states that for every action there is an equal and opposite reaction. Meaning, when you hit the hammer on the board the same amount of energy that is going into the board, is going into the hammer. Causing the hammer to bounce off the board.
