HESI Exams Quizlet Physics

Correct Answer: C

Rationale: The correct answer is C: Zero. Inside a hollow conductor with a net charge, the electric field is zero due to electrostatic shielding. Charges within the conductor redistribute to cancel out the electric field inside, resulting in a net zero field. This is a fundamental property of conductors in electrostatic equilibrium. Explanation for other choices: A: Remains constant - Electric field inside a hollow conductor with a net charge does not remain constant; it is zero. B: Decreases - Electric field does not decrease inside a hollow conductor with a net charge; it is zero. D: Becomes unpredictable - The electric field inside a hollow conductor with a net charge is predictable and known to be zero due to redistribution of charges.

Correct Answer: A

Rationale: The correct answer is A: a compression. Transverse waves move perpendicular to the direction of the wave motion, so they do not have compressions, which are characteristic of longitudinal waves. Transverse waves have an amplitude (maximum displacement of the wave), a frequency (number of wave cycles per unit time), and a wavelength (distance between two consecutive wave peaks). Therefore, choice A is the correct answer as it is the only characteristic that transverse waves do not possess. Choices B, C, and D are incorrect because they are all characteristics of transverse waves.

Correct Answer: A

Rationale: Semiconductors fall between conductors and insulators in terms of electrical conductivity because they have conductivity levels higher than insulators but lower than conductors. Conductors have high conductivity due to abundant free electrons, while insulators have very low conductivity due to the lack of free electrons. Semiconductors can conduct electricity under certain conditions by manipulating the number of free electrons through doping or applying electric fields. Therefore, choice A is correct. Choices B, C, and D are incorrect because they do not accurately represent the conductivity levels of semiconductors in relation to other materials.
