Question 49: Which law explains why a rocket can move in space?

The Law of Conservation of Energy
Newton's Second Law
Newton's Third Law (Correct answer)
Newton's First Law

Correct answer: Newton's Third Law

Newton's Third Law states that for every action, there is an equal and opposite reaction. A rocket expels hot gases downwards (action), and in response, the gases exert an equal and opposite force upwards, propelling the rocket forward. This principle allows the rocket to accelerate even in the vacuum of space, as it doesn't need air to push against.

Question 112: What is the principle of conservation of energy?

Energy can neither be created nor destroyed, only transformed. (Correct answer)
Energy is always increasing in a closed system.
Energy can be created by converting mass.
Energy is only conserved in isolated systems.

Correct answer: Energy can neither be created nor destroyed, only transformed.

The principle of conservation of energy, also known as the First Law of Thermodynamics, states that energy cannot be created or destroyed within a closed system. Instead, it can only be transformed from one form to another, such as from potential energy to kinetic energy or chemical energy to heat. The total amount of energy in the universe remains constant, only changing its manifestation.

Correct answer: Hydrochloric acid

A strong acid is one that completely dissociates into its ions when dissolved in water, meaning nearly all its molecules release hydrogen ions (H+). Hydrochloric acid (HCl) is a classic example of a strong acid, dissociating fully into H+ and Cl- ions. In contrast, acetic acid, citric acid, and carbonic acid are weak acids, which only partially dissociate.

Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus. This process is crucial for growth, repair, and asexual reproduction in eukaryotic organisms, ensuring genetic identicalness between parent and daughter cells. Meiosis, in contrast, produces four genetically distinct haploid cells for sexual reproduction.
