May/June 2021 · Paper 1 · Mass and weight
Which row shows a possible mass and weight of an object on the Earth's surface?
[gravitational field strength g = 10 N / kg]
- mass 2 kg, weight 0.20 N
- mass 2 kg, weight 10 N
- mass 5 kg, weight 5.0 N
- mass 5 kg, weight 50 N
Show answer and explanation
Answer: D. mass 5 kg, weight 50 N
Weight = mass × g, so 5 kg × 10 N / kg = 50 N; the other rows do not satisfy W = mg.
May/June 2021 · Paper 1 · Pressure — gases
A sealed gas syringe contains a fixed mass of gas.
The piston is moved and the volume of the gas doubles. The temperature of the gas does not change.
What happens to the pressure of the gas?
- halves
- no change
- doubles
- triples
Show answer and explanation
Answer: A. halves
For a fixed mass of gas at constant temperature pV is constant, so doubling the volume halves the pressure.
May/June 2021 · Paper 1 · Pressure in liquids
At a depth d in sea-water, the total pressure experienced by a diver is 2P, where P is atmospheric pressure.
At which depth is the total pressure 4P ?
- 1.5d
- 2d
- 3d
- 4d
Show answer and explanation
Answer: C. 3d
At depth d the water alone contributes 2P − P = P, and pressure in a liquid is proportional to depth, so 3P from the water needs a depth of 3d, giving a total of 4P.
May/June 2021 · Paper 1 · Energy — efficiency and power
Some solar panels have a total area of 12 m².
Each 1.0 m² of the panels receives 0.85 kJ of energy from the Sun in 1.0 s.
The efficiency of the panels is 16%.
How much power do they produce?
- 1.6 kW
- 2.2 kW
- 64 kW
- 160 kW
Show answer and explanation
Answer: A. 1.6 kW
The input power is 12 × 850 = 10 200 W, and 16% of this is 0.16 × 10 200 = 1632 W, about 1.6 kW.
Common questions
