A device measures a charge of 3000 nC. Convert it into microcoulombs (µC).
- 0.03 µC
- 3 µC
- 30 µC
- 300 µC
Show answer and explanation
Answer: B. 3 µC
1 µC = 1000 nC, so 3000 nC = 3 µC.

What is a reasonable estimate for the mass of a physics textbook?
- 2 mg
- 1 kg
- 10 kg
- 1 g
Show answer and explanation
Answer: B. 1 kg
A textbook has a mass of the order of 1 kg.
A hypothesis is best described as:
- A testable prediction
- A universally accepted fact
- A mathematical equation
- A proven theory
Show answer and explanation
Answer: A. A testable prediction
A hypothesis is a tentative, testable explanation or prediction.
1 milligram =
- 10⁻³ g
- 10⁻⁶ g
- 10⁻¹² g
- 10⁻¹⁵ g
Show answer and explanation
Answer: A. 10⁻³ g
milli = 10⁻³, so 1 mg = 10⁻³ g.
Which branch of physics deals with nature and properties of light?
- Astronomy
- Cosmology
- Acoustics
- Optics
Show answer and explanation
Answer: D. Optics
Optics is the study of light; acoustics deals with sound.
The branch of physics that deals with the behaviour of microscopic particles is:
- Electricity
- Magnetism
- Optics
- Quantum Mechanics
Show answer and explanation
Answer: D. Quantum Mechanics
Quantum mechanics describes atoms, electrons and other microscopic particles.
Briefly describe the following branches of physics: (a) Optics, (b) Cosmology, (c) Biophysics.
Show model answer
(a) Optics — the study of light: its nature, propagation, reflection, refraction, lenses, mirrors and optical instruments.
(b) Cosmology — the study of the origin, structure, evolution and eventual fate of the universe as a whole (Big Bang, expansion of the universe).
(c) Biophysics — the application of the principles and methods of physics to biological systems, e.g. mechanics of muscles, physics of hearing and vision, medical imaging.
What is the difference between classical mechanics and quantum mechanics?
Show model answer
Classical mechanics (Newtonian mechanics) describes the motion of macroscopic objects — cars, planets, projectiles — moving at speeds much smaller than light. It is deterministic: position and velocity can be known exactly.
Quantum mechanics describes the behaviour of microscopic particles — atoms, electrons, photons — where energy is quantised and particles show wave properties. It is probabilistic (uncertainty principle) and classical laws fail at this scale.
