physics

1. What property of a substance refers to its ability to undergo a chemical change and form new substances?

Correct answer: c

Rationale: Reactivity refers to a substance's ability to undergo a chemical change or reaction, forming new substances with different properties.

2. Which part of the neuron is responsible for transmitting signals away from the cell body and toward other neurons or muscles?

Correct answer: a

Rationale: The correct answer is 'A: Axon.' The axon is a long, slender projection of a neuron that carries nerve impulses away from the cell body towards other neurons or muscles. It acts as the primary transmission line of the nervous system, sending electrical signals known as action potentials. Dendrites, on the other hand, receive signals from other neurons and transmit them towards the cell body. The synapse is the junction between two neurons where communication occurs. The myelin sheath is a fatty substance that surrounds and insulates the axon, speeding up the transmission of nerve impulses. Therefore, the axon is specifically responsible for transmitting signals away from the cell body, making it the correct answer.

3. Identify the type of clause in the sentence "When the clock struck midnight, the magic began."

Correct answer: B

Rationale: The "when" clause introduces additional information about the main sentence and acts as a subordinate clause.

4. What is the half-life of a radioactive isotope, and how does it relate to its decay rate?

Correct answer: A

Rationale: Half-life tells the time it takes for half of the original radioactive nuclei to decay, offering an indication of the decay rate.

5. In a horizontal chart, the lowest level worker is located at the

Correct answer: B

Rationale: In a horizontal chart, the lowest level worker is typically positioned at the leftmost side, with higher-level workers placed to the right. This arrangement signifies hierarchy, with the top level usually being on the rightmost side. Therefore, the correct answer is B: 'Middle,' as the lowest level worker is situated towards the left of the chart, not the extreme left or right. This positioning helps visually represent the organization's structure and indicates the progression from lower to higher levels as one moves from left to right on the chart.

6. What happens to the concentration of hydrogen ions (\([H^+]\)) in a solution as the pH increases?

Correct answer: B

Rationale: As the pH increases, the concentration of hydrogen ions decreases. The relationship is inversely proportional
