Section A: Multiple Choice Questions

This page begins Section A of the exam, which consists of multiple choice questions. Students are advised to spend a maximum of 30 minutes on this section.

Question 1 tests understanding of Faraday's law of electromagnetic induction. The correct answer is D: electromotive force, linkage.

Question 2 relates to the diffraction and interference of monochromatic laser light incident on a diffraction grating. The correct answer is A: diffraction, interference.

Definition: Faraday's law of electromagnetic induction states that the induced electromotive force in a circuit is directly proportional to the rate of change of magnetic flux linkage.

Example: When monochromatic light passes through a diffraction grating, it produces a series of bright spots on a distant screen due to constructive interference of diffracted light waves.

Multiple Choice Questions Continued

This page continues with multiple choice questions from Section A.

Question 3 involves calculating energy transfer in an electrical circuit. The correct answer is D: 130 J.

Question 4 tests understanding of electric fields and potentials between charged spheres. The correct answer is C: The direction of the electric field at P is to the left.

Question 5 relates to a circuit with light-emitting diodes (LEDs). Students must determine which LEDs are lit based on the circuit diagram. The correct answer is D: Q and S.

Example: To calculate energy transfer in an electrical circuit, use the formula E = VIt, where V is voltage, I is current, and t is time.

Vocabulary: Electric field - A region around a charged particle or object within which a force would be exerted on other charged particles or objects.

Capacitor Discharge and Thermistor Circuit

This page contains questions 6 and 7 of Section A.

Question 6 involves modeling the decay of charge for a capacitor discharging through a resistor. Students must interpret a spreadsheet to determine the charge remaining after a certain time. The correct answer is C: 729 μC.

Question 7 presents a circuit with a thermistor and asks students to calculate the total potential difference across components. The correct answer is B: 7.0 V.

Definition: A thermistor is a temperature-sensitive resistor whose resistance changes significantly with temperature.

Highlight: Understanding capacitor discharge and thermistor behavior is crucial for analyzing various electrical and electronic systems.

View

Interference and Sound Waves

This page covers questions 8 and 9 of Section A.

Question 8 deals with a double-slit interference experiment using two light sources with different wavelengths. Students must calculate the separation between adjacent bright fringes. The correct answer is C: 1.9 mm.

Question 9 involves analyzing a stationary sound wave in a tube closed at one end. Given the tube length and speed of sound, students must determine the frequency of the sound wave. The correct answer is A: 97 Hz.

Example: In a double-slit experiment, the separation between bright fringes is given by the formula y = λD/d, where λ is wavelength, D is distance to the screen, and d is slit separation.

Vocabulary: Stationary wave - A wave that remains in a constant position, formed by the interference of two waves traveling in opposite directions.

Circuit Analysis

This final page of the provided transcript contains question 10 of Section A.

The question presents a circuit with a battery and multiple resistors. Students must analyze the circuit to determine the power dissipated in one of the resistors.

Key information provided:

Battery EMF: 6.0 V
Total current from battery: 30 mA
Current in resistor X: 10 mA
Resistors Y and Z are identical

Students are asked to calculate the power dissipated in resistor Z. The options given range from 30 mW to 60 mW.

Highlight: This question tests students' ability to apply Ohm's law and power calculations in a complex circuit scenario.

Vocabulary: EMF (Electromotive Force) - The energy per unit charge available from a source of electrical energy such as a battery.
