(All answers in cm) (1) 930, 000 plusminus 100 (2) 930, 000 plusminus 1000 (3) 930, 000 plusminus 10 (4) 930, 000 plusminus 1 (5) (9.30 plusminus l) times 10^5 (6) (9.3 plusminus .1) times 10^5 (7) (9.300 plusminus .001) times 10^5 (8) (9.3000 plusminus .0001) times 10^5 (9) (9.30000 plusminus .000001): times 10^5 A measurement between 920, 000 cm and 940, 000 cm. (Choose from answers to previous question.) A measurement between 929, 999cm and 930, 001 cm. (Can you imagine any way of measuring the distance so accurately as this?)

Explanation / Answer

On computing these measurements we get these equal to following

1)930100 to 929900

2) 931000 to 929000

3)930010 to 929990

4)930001 to 929999

4)930001 to 929999

5)930001 to 929999

6)930000.1 to 929999.9

7)930000.001 to 929999.999

8)930000.0001 to 929999.9999

9)930000.000001 to 929999.999999

26. 3,4,5,6,7,8,9 are between specified range on the basis of above computation .

27. 1,2,3,4,56,7,8,9

28. 6,7,8,9

The method similar to define one metre standard can be used . The distance can be measured in terms of number of wavelengths of certain emission lines of Krypton -86 that fit in the distance to be measured.
