Physics

1. A ball is thrown upwards. Which of the following statements is TRUE about its potential energy and kinetic energy at the peak of its trajectory?

Correct answer: B

Rationale: At the peak, the ball momentarily stops moving, minimizing kinetic energy. However, it's still at its highest point, maximizing its potential energy due to gravity.

2. Which element has the same number of protons and neutrons?

Correct answer: D

Rationale: Helium (He) - He-4 has 2 protons and 2 neutrons, while the other options have differing numbers.

3. A medication must be taken twice daily, 12 hours apart. If the first dose is at 8:00 AM, what is the most convenient time for the second dose to avoid disrupting sleep?

Correct answer: B

Rationale: Rationale: To take the medication 12 hours apart from the first dose at 8:00 AM, the second dose should be taken at 8:00 PM. However, to avoid disrupting sleep, it is recommended to take the second dose a bit earlier. Taking the second dose at 6:00 PM ensures that the medication is still being taken 12 hours apart while allowing for a buffer before bedtime to avoid any potential disruptions to sleep.

4. Which statement BEST summarizes the author's perspective on bioremediation for plastic pollution?

Correct answer: B

Rationale: The passage acknowledges the potential of bioremediation while highlighting the need for further research, indicating a balanced perspective.

5. Which statement is TRUE about valence electrons?

Correct answer: C

Rationale: They are most likely to participate in chemical bonding - Valence electrons occupy the outermost shell and are readily involved in forming bonds with other atoms.

6. What property of a wave is responsible for determining its energy?

Correct answer: a

Rationale: The amplitude of a wave determines its energy, with higher amplitudes corresponding to higher energy levels.
