- 0.10 m³
- 0.50 m³
- 1.0 m³
- 2.0 m³
Show answer and explanation
Answer: A. 0.10 m³
A person of mass ~70 kg and density close to that of water (1000 kg m⁻³) has a volume of about 0.07–0.1 m³.

A signal of frequency 25 Hz is displayed on the screen of a cathode-ray oscilloscope. The trace shows 4 complete cycles occupying 8 cm of the screen, with the grid marked in 1 cm squares. What is the time-base setting?
- 10 ms cm⁻¹
- 20 ms cm⁻¹
- 25 ms cm⁻¹
- 40 ms cm⁻¹
Show answer and explanation
Answer: B. 20 ms cm⁻¹
Period T = 1/25 = 40 ms occupies 2 cm on screen (8 cm / 4 cycles), so the time-base is 40/2 = 20 ms cm⁻¹.
A rocket is fired from the Earth into space. Newton's third law of motion describes how forces act in pairs. One of the forces of a pair is the weight of the rocket. What is the other force of this pair?
- air resistance
- force of the exhaust gases on the rocket
- force of the rocket on the exhaust gases
- gravitational force of the rocket on the Earth
Show answer and explanation
Answer: D. gravitational force of the rocket on the Earth
The weight of the rocket is the Earth's gravitational pull on the rocket; its Newton's-third-law pair is the rocket's equal and opposite gravitational pull on the Earth.
(a) A proton in a nucleus decays to form a neutron and a β⁺ particle.
(i) State the name of another lepton that is produced in the decay. [1]
(ii) State the name of the interaction (force) that gives rise to this decay. [1]
(iii) State which of the three particles (proton, neutron or β⁺ particle) has the largest ratio of charge to mass. [1]
(iv) Use the quark model to show that the charge on the proton is +e, where e is the elementary charge. [2]
(v) Describe the change to the quark composition of the proton during the decay. [1]
(b) A nucleus X (¹²₆X) and a nucleus Y (¹⁶₈Y) are accelerated by the same uniform electric field.
(i) Determine the ratio: electric force acting on nucleus X ÷ electric force acting on nucleus Y. [2]
(ii) Determine the ratio: acceleration of nucleus X due to the field ÷ acceleration of nucleus Y due to the field. [1]
(iii) Nucleus X is at rest in the uniform electric field at time t = 0. The field causes nucleus X to accelerate so that it moves through the field. Describe the variation with time t of the acceleration a of nucleus X due to the field. [1]
Show model answer
(a)(i) An (electron) neutrino is also produced.
(a)(ii) The weak (nuclear) interaction/force gives rise to this decay.
(a)(iii) The β⁺ particle (positron) has the largest charge-to-mass ratio, since it has the same magnitude of charge as a proton or neutron but a far smaller mass.
(a)(iv) The proton's quark structure is up, up, down (uud). Charge = (+2/3)e + (+2/3)e + (−1/3)e = +e.
(a)(v) One up quark changes to a down quark: the quark composition changes from up-up-down (uud) to up-down-down (udd).
(b)(i) Nucleus X (¹²₆X) has charge 6e, nucleus Y (¹⁶₈Y) has charge 8e. Since F = Eq for the same field E, ratio = 6e/8e = 6/8 = 0.75. …
