Question
Fill in the blank by suitable conversion of unit:
3.0 m s–2= ______ km h–2
Solution
3.0 m s–2= 3.888 × 104 km h–2
Explanation:
1 m = 10–3 km
Again 1 s = `1/3600 h`
1 s–1 = 3600 h–1
1 s–2 = (3600)2 h–2
∴ 3 m s–2 = (3 × 10–3 km) × ((3600)2 h–2)
= 3.888 × 104 km h–2

Explain this statement clearly:
“To call a dimensional quantity ‘large’ or ‘small’ is meaningless without specifying a standard for comparison”. In view of this, reframe the following statements wherever necessary:
- Atoms are very small objects
- A jet plane moves with great speed
- The mass of Jupiter is very large
- The air inside this room contains a large number of molecules
- A proton is much more massive than an electron
- The speed of sound is much smaller than the speed of light.
A famous relation in physics relates ‘moving mass’ m to the ‘rest mass’ m0 of a particle in terms of its speed v and the speed of light, c. (This relation first arose as a consequence of special relativity due to Albert Einstein). A boy recalls the relation almost correctly but forgets where to put the constant c. He writes:
`m = m_0/(1-v^2)^(1/2)`
Guess where to put the missing c.
