3.4, 3.3
A technician compares two spring bumpers for a horizontal trolley. Spring A has a straight force-extension loading graph through the origin. Spring B has a curved loading graph but returns fully to its original length when unloaded. Both are used within a...
Motion
A student uses a trapdoor and electromagnet arrangement to measure the acceleration of free fall. When the electromagnet releases a steel ball, an electronic timer starts. The ball falls through the trapdoor, which breaks an electrical circuit and stops the...
Forces and Motion
A skydiver steps out of a stationary hot-air balloon and falls. Some way down she opens her parachute, and eventually lands safely. Describe and explain the motion of the skydiver from the instant she steps out until she lands. Your answer should refer to...
Nuclear Physics
The graph of binding energy per nucleon against nucleon number rises steeply, peaks near iron, and then falls slowly. Using the idea of binding energy per nucleon, explain why energy is released in both nuclear fusion and nuclear fission, and why iron is the...
Practical Skills
Describe how you would accurately determine the density of a small, irregularly shaped stone using standard laboratory equipment. Your answer should explain which measurements you would take, the equipment you would use, and how you would reduce the...
Astrophysics
Astronomers observe a distant galaxy and measure the wavelength of a specific hydrogen spectral line to be 660 nm. The same hydrogen line, when observed in a laboratory on Earth, has a wavelength of 656 nm. Explain how these observations provide evidence for...
Forces and Motion, Quantum
Discuss how the photoelectric effect provides evidence for the particulate nature of electromagnetic radiation, and explain why the wave model of light fails to account for the observed phenomena.
