Question 2

In an experiment demonstrating the photoelectric effect, it is observed that electrons are only ejected from a metal surface if the incident light's frequency exceeds a specific threshold, irrespective of the light's intensity. Furthermore, for frequencies above this threshold, increasing the light's intensity increases the *number* of ejected electrons, but not their *maximum kinetic energy*. This set of observations provides strong evidence for which of the following?

Accepted Answer

C. The quantum nature of light, where energy is transferred in discrete packets called photons. — Option C accurately reflects that the quantum nature of light, specifically the photon concept (E=hν), is required to explain the observed phenomena of the photoelectric effect. The existence of a threshold frequency implies that energy is transferred in discrete packets (photons), each needing sufficient energy to overcome the metal's work function. Classical wave theory (Option B) fails to explain the threshold frequency and predicts that electron kinetic energy should increase with light intensity, contradicting observations. Options A and D are unrelated or do not provide the fundamental e

Answer

A. The inverse square law governing the intensity of light.

Answer

B. The classical wave theory of light, predicting continuous energy transfer to electrons.

Answer

D. The principle of conservation of momentum in light-matter interactions.

Question 4

A patient diagnosed with a terminal illness repeatedly claims that the doctors have made a mistake and that they are perfectly healthy. Which defense mechanism is this patient primarily utilizing?

Accepted Answer

B. Denial — Denial is a defense mechanism where an individual refuses to accept reality or a fact. In this scenario, the patient is refusing to acknowledge the terminal diagnosis. Repression involves unconsciously pushing distressing thoughts into the unconscious, while projection involves attributing one's own unacceptable thoughts to another person, and sublimation channels unacceptable impulses into socially acceptable ones.

Answer

A. Repression

Answer

C. Projection

Answer

D. Sublimation

Question 9

The presence of glucose in a routine urine analysis (glycosuria) in a non-diabetic individual could indicate a problem primarily with which organ's function?

Accepted Answer

C. Kidney — In a non-diabetic individual, glucose should not be present in the urine because the kidneys efficiently reabsorb almost all filtered glucose in the renal tubules. Glycosuria in this context, without hyperglycemia, suggests a defect in the renal tubules' ability to reabsorb glucose. This condition is known as renal glycosuria, indicating a primary kidney problem.

Answer

A. Liver

Answer

B. Pancreas

Answer

D. Adrenal gland
