Hello!
Kinetic Energy (1/2 · mass · velocity²) arises when an object is moving, or when a force acts on it. For example, a moving car demonstrates this principle.
Potential energy (mass · height · gravity) exists when an object has the capacity to perform work. An example would be an item resting on a shelf. It possesses the potential to fall, converting its potential energy into kinetic energy.
-----------------------------------------------------------------------------------------------------------
By examining the examples from the table, we categorize them as follows:
Girl swimming laps- Kinetic energy as the girl is in motion.
Boy standing on diving board - Potential energy since the boy is still but has the potential to move.
Girl striking volleyball - Kinetic energy as the volleyball is actively moving.
Boy grasping volleyball- Potential energy since the volleyball is at rest and can potentially be set in motion.
Thus, the accurate classification is table 1.
Answer:
d. One additional neutron
Explanation:
Phosphorus-32, a radioactive variant of phosphorus, possesses 15 protons and 17 neutrons.
Conversely, Phosphorus-31, the most prevalent isotope of phosphorus, contains 15 protons and 16 neutrons.
This indicates that one isotope has one more neutron than the other.

The right answer is B. DNA helicase initially unwinds the double helix surrounding the +1 site.
1) Magnification increases through powers like 10x, 100x, 1000x, and even up to 10,000x.
2) Begin focusing with the lowest magnification lens, usually 10x; once in focus, switch to medium power (100x) and fine-tune using the fine adjustment knob. Avoid using the coarse focus on medium or high powers. Then move to the highest power (typically 1000x), and carefully focus again with the fine knob.
3) To keep the lens clean and prevent dust or fog buildup, proper handling and storage are necessary.
