A parachutist has reached a first terminal velocity before opening a parachute. Consider the motion from just before opening until a new terminal velocity is reached.
Explain the changes in resultant force, acceleration and speed throughout this sequence.

An engineer needs an electromagnet that lifts a metal latch reliably but does not overheat during repeated use. The design can change current, number of turns and core material.
Plan tests to compare designs and explain the scientific reasons for the measurements and controls.

An imaging leaflet gives typical effective doses: one chest X-ray 0.020 mSv and one CT examination 4.0 mSv. These values are supplied; you do not need to recall dose units.
.1
Calculate the number of chest X-rays giving the same listed total dose as one CT examination.
[2 marks]
.2
Explain why the dose comparison alone cannot decide whether a patient should have the CT examination.

Original practice question
Answer and supported method checks
Students want to compare wave speeds on the same stretched string at two different tensions. They have a vibration generator, signal generator, pulley, masses, metre rule, a high-speed camera with a short exposure and an absorbing termination that suppresses reflected waves before the pulley. The camera resolves individual travelling-wave crests.
Plan a valid comparison using measurements of frequency and wavelength.

Original practice question
Answer and supported method checks
A manufacturer claims a rubber luggage strap is more suitable than a steel spring for repeated stretching under load. A fair comparison must use the same maximum applied force and check whether each sample returns to its original length.
Plan an investigation to compare how extension depends on force for the strap and spring, and test whether they recover their original lengths after repeated loading.
