P4 General Studies: Sound, Vibration and Hearing (Paper 4 (error clinic))

Paper four revisits the mistakes from the first three papers, fixing numbers and ideas together.

Direct answers Decide first whether the question asks about pitch, loudness, medium or distance, then calculate.

01 Paper details (check answers afterwards)

Item Detail
Questions 10
Suggested time 20
Difficulty mix Foundation 3 · Intermediate 3 · Challenge 3 · Error redo 1
Chapter Chapter: P4 General Studies: Sound, Vibration and Hearing
Level parts of a closed circuit, conductors against insulators, series against parallel, adding up battery voltage, and electrical safety

02 Questions (10 items)

  1. FoundationIs any sound heard once a tuning fork stops vibrating?
  2. FoundationOn the Moon, which has no air, can a companion hear you speak directly?
  3. FoundationWhat is the main job of the outer ear?
  4. IntermediateThree of 4 tuning forks are above 400 Hz. What proportion is that, in percentage points?
  5. IntermediateThe frequency rises from 100 Hz to 300 Hz. What is the increase in percentage points?
  6. IntermediateA shout returns from a wall after 0.5 seconds. How far is the wall? (sound at 340 m/s)
  7. ChallengeHow do pitch and loudness differ?
  8. ChallengeSound from the poolside is still heard underwater. What does that show?
  9. ChallengeFifteen of 20 instruments are percussion. What proportion is that, in percentage points?
  10. Error redoError clinic: sound can only travel through air. Is that right?

03 Answers and one-line notes

# Answer One-line note
1 No. Sound comes from vibration, so it ends when the vibration ends.
2 No. The surface is near vacuum with no medium, so radio is used instead.
3 To collect sound waves and guide them into the ear canal. It does not create hearing; it gathers sound and funnels it inwards.
4 75.0 percentage points. Three divided by 4 then multiplied by 100 gives 75.0 percentage points.
5 200.0 percentage points. The rise is 200 Hz, which is 200.0 percentage points of the original 100 Hz.
6 85.0 m. 340 times 0.5 divided by 2 gives 85.0 metres.
7 Pitch follows frequency while loudness follows amplitude. A sound can be high and soft at once, so the two are judged separately.
8 Liquids carry sound too; water acts as a medium. Solids, liquids and gases all carry sound; only a vacuum cannot.
9 75.0 percentage points. Fifteen divided by 20 then multiplied by 100 gives 75.0 percentage points.
10 No. Solids and liquids carry sound as well; only a vacuum cannot. Air is just one medium.

04 What to do after marking

  • After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
  • Repeat the same item two days later; move to the next paper only when both attempts are correct.
  • Parents only need the answer and note columns; there is no need to explain every item.

With all four done, go back to the chapter page and revise the three parts of a closed circuit plus three safety habits.Tutor Registration →
