Physics 7408/2 June 2019

The AQA Paper 2 Physics exam (June 2019) covers a range of topics including thermodynamics, gas laws, electrostatics, oscillations, and nuclear physics. It starts with questions on the specific heat capacity and latent heat of nitrogen, moving through kinetic theory and the pressure exerted by gases. The exam explores gravitational potential, escape velocity, and the forces on charged spheres in equilibrium. It further delves into concepts of electromagnetic induction in a rotating coil, nuclear reactor functioning, and the process of neutron energy reduction. Additionally, questions involve the application of physics to safety barriers, the behavior of capacitors, and fission energy calculations. The exam emphasizes both practical and theoretical understanding in physics.
