A series is given with one term missing. Select the correct alternative from the given ones that will complete the series.
Millimetre, Micrometre, Nanometre, ?
- APicometre
- BKilometre
- CMetre
- DCentimetre
Solution & Step-by-step Explanation
The series lists units of length decreasing by a factor of 10
−3
(1000 times smaller at each step):
Millimetre = 10
−3
m
Micrometre = 10
−6
m
Nanometre = 10
−9
m
The next unit in this descending sequence is Picometre = 10
−12
m.
