Question 7

A monochromatic light source illuminates a metal surface, causing photoelectrons to be emitted. If the intensity of the light is doubled while keeping its frequency constant, what would be the observed change in the photoelectric current and the maximum kinetic energy of the emitted photoelectrons?

Accepted Answer

A. Photoelectric current doubles, maximum kinetic energy remains constant. — Doubling the intensity of light, while keeping its frequency constant, increases the number of photons incident on the metal surface per unit time. This leads to a proportional increase in the number of emitted photoelectrons, hence doubling the photoelectric current. However, the maximum kinetic energy of the emitted photoelectrons depends solely on the frequency of the incident light and the work function of the metal, remaining unaffected by changes in intensity.

Answer

B. Photoelectric current remains constant, maximum kinetic energy doubles.

Answer

C. Both photoelectric current and maximum kinetic energy double.

Answer

D. Both photoelectric current and maximum kinetic energy remain constant.

Question 9

What is the primary characteristic that distinguishes action research from traditional academic research in an educational setting?

Accepted Answer

A. It is conducted by practitioners to solve immediate, specific problems in their own context. — Action research is fundamentally participatory and contextual, focusing on practical problem-solving and improvement within the practitioner's own setting. Unlike traditional research, its primary goal is not generalizability or theory-building, but rather immediate, localized change. Options B, C, and D describe characteristics more aligned with traditional, formal research.

Answer

B. It primarily aims to generate generalizable theories applicable across diverse settings.

Answer

C. It strictly adheres to pre-defined experimental designs and statistical analyses.

Answer

D. It requires extensive external funding and approval from institutional review boards.
