1. Where is the gastrocnemius vein in relation to the femoral vein?

• A. Lateral
• B. Distal
• C. Superior
• D. Ventral

Correct answer: A

Rationale: The gastrocnemius vein is located lateral to the femoral vein. In anatomical terms, lateral refers to the direction towards the side of the body or away from the midline. In this case, the gastrocnemius vein is positioned to the side of the femoral vein. The term 'distal' refers to being further away from the point of reference, 'superior' indicates a higher position, and 'ventral' refers to the front or anterior aspect of the body. Therefore, the correct answer is A. Lateral.

2. Which orbital can hold a maximum of 8 electrons?

• A. s orbital
• B. p orbital
• C. d orbital
• D. f orbital

Correct answer: B

Rationale: The correct answer is the p orbital. Each p orbital can hold a maximum of 6 electrons (2 electrons in each of the 3 p orbitals), totaling 18 possible electrons when considering all three p orbitals. The s orbital can hold a maximum of 2 electrons, the d orbital can hold a maximum of 10 electrons, and the f orbital can hold a maximum of 14 electrons. Therefore, the p orbital is the orbital that can hold a maximum of 8 electrons, making it the correct choice.

3. What happens to the force of gravity between two objects when the distance between them is doubled?

• A. The force increases by a factor of 2
• B. The force increases by a factor of 4
• C. The force decreases by a factor of 2
• D. The force decreases by a factor of 4

Correct answer: D

Rationale: According to the law of universal gravitation, the force of gravity between two objects is inversely proportional to the square of the distance between them. When the distance is doubled, the force decreases by a factor of 2 squared, which is 4. Therefore, the force decreases by a factor of 4. Choice A is incorrect because the force doesn't increase when the distance is doubled. Choice B is incorrect as the force doesn't increase but actually decreases. Choice C is incorrect as the force decreases by a factor of 4, not 2.

4. An atom has 5 protons, 5 neutrons, and 6 electrons. What is the electric charge of this atom?

• A. Neutral
• B. Positive
• C. Negative
• D. Undetermined

Correct answer: C

Rationale: The correct answer is 'Negative.' An atom becomes negatively charged when it has more electrons than protons. In this case, the atom has 6 electrons and 5 protons, resulting in a net negative charge. Choice A 'Neutral' is incorrect because the atom is not balanced in terms of protons and electrons. Choice B 'Positive' is incorrect because having more electrons than protons results in a negative charge. Choice D 'Undetermined' is incorrect, as the charge can be determined based on the relative number of protons and electrons.

5. Which type of orbital can hold a maximum of 10 electrons?

• A. s orbital
• B. p orbital
• C. d orbital
• D. f orbital

Correct answer: D

Rationale: The correct answer is the f orbital. Each f orbital can hold up to 2 electrons. Since there are 5 f orbitals, the total maximum number of electrons that can be accommodated in f orbitals is 10 (2 electrons per orbital x 5 orbitals = 10 electrons). Therefore, the f orbital can hold a maximum of 10 electrons. Choice A, s orbital, is incorrect because it can hold a maximum of 2 electrons. Choice B, p orbital, is incorrect because it can hold a maximum of 6 electrons (3 orbitals x 2 electrons per orbital = 6 electrons). Choice C, d orbital, is incorrect as it can hold a maximum of 10 electrons (5 orbitals x 2 electrons per orbital = 10 electrons), but the question asks for the type of orbital that can hold a maximum of 10 electrons, not the total number of electrons in d orbitals.
