2026 P2 Q1Current ElectricityDrift velocity:
how fast do electrons move?Connect wire resistance, electron density and current to find the electron drift velocity in a long metal wire.Open study companion ↗2026 P2 Q2RadioactivityRadioactive build-up:
how fast does temperature rise?Watch a nuclide produced at constant rate approach decay equilibrium and heat a liquid with a rising temperature-rate curve.Open study companion ↗2026 P2 Q3OpticsThin prism dispersion:
where is deviation minimum?Use the wavelength-dependent refractive index to find the colour for which a thin prism gives the smallest minimum deviation.Open study companion ↗2026 P2 Q4Central Force MotionRadial oscillations:
what is the period?Displace an inverse-square circular orbit slightly in radius and watch the effective radial force become a harmonic restoring force.Open study companion ↗2026 P2 Q6Charged Particle MotionElectric to magnetic field:
which statements remain true?Track a charged particle first under electric field and gravity, then under magnetic field and gravity, to verify the vertical distances and circular radius.Open study companion ↗
