A bar magnet is dropped through a copper ring. (a) Sketch the induced EMF graph against time as the magnet enters, passes through, and leaves the ring. (b) Explain the direction of the induced current as the magnet approaches the ring. ib physics hl question bank by topic top
While sitting a full 2024 past paper is great for timing, it’s a poor way to learn. If you struggle with Topic 12: Quantum and Nuclear Physics , seeing one question every hour isn't going to fix the gap in your knowledge.
Specifically designed for IB Physics, PaperPlainz offers a streamlined experience. Their "Topic Quizzes" and "Question Bank" are perfectly aligned with the latest syllabus. If you want, I can: : Specializes in
A ball is launched from the top of a cliff $20 \text m$ high with a horizontal velocity of $15 \text m s^-1$. (a) Determine the time taken for the ball to reach the ground. (b) Calculate the horizontal distance travelled. (c) Determine the magnitude and direction of the velocity just before impact.
An electric heater of power $50 \text W$ is used to heat $0.2 \text kg$ of water. The temperature of the water rises from $20^\circ\textC$ to $40^\circ\textC$ in 5 minutes. Calculate the specific heat capacity of the water and suggest why this value might differ from the theoretical value. (a) Sketch the induced EMF graph against time
syllabus structure (pre-2025), so you’ll need to filter out topics that are no longer relevant (like the old Options). 3. Save My Exams
