2. The S.I unit for density is
- A. ms$^{-1}$
- B. ms$^{-2}$
- C. kg m$^{-3}$
- D. m$^{3}$kg$^{-1}$
Answer: C. kg m$^{-3}$
Answer: C. Density = mass/volume, so its S.I. unit is kg m⁻³.
Answer: C. Density = mass/volume, so its S.I. unit is kg m⁻³.
3. When light travels from glass to air, its speed is
- A. increased.
- B. reduced.
- C. halved.
- D. unchanged.
Answer: A. increased.
Answer: A. Light travels faster in air than in glass, so its speed increases.
Answer: A. Light travels faster in air than in glass, so its speed increases.
4. When a piece of iron rod is brought near a permanent magnet for a while it becomes magnetised by
- A. stroking method.
- B. electrical method.
- C. friction.
- D. induction.
Answer: D. induction.
Answer: D. Placing iron near a magnet magnetises it by induction.
Answer: D. Placing iron near a magnet magnetises it by induction.
5. A rheostat is used in an electric circuit in order to
- A. increase electric current only.
