Question # 7
Which of the following has the least value?
Question # 8
how many characteristics a physical quantity possesses?
Question # 9
In which of the following values, all the zeros are significant?
Leading zeros (zeros before the first non-zero digit) are not significant.
Question # 10
If you are not able to understand or do a part of experiment, what should you do?
Question # 11
Why was platinum-Iridium used to make standard of mass?
Such material should be used to make standard of mass, whose physical quality minimises surface contamination and enhances the mass stability of the artefact.

Question # 22
At which position of the pointer, the lever balance is balanced and we get the value of mass of the substance?
Question # 23
Which of the following physical quantity unit is same for all systems?
Many units are expressed different in physical unit systems, e.g., the basic unit of length in Imperial system is yard which is equivalent to 0.9144 m (In SI unit system).
