Sample questions
-
1.Assertion (A): 4.700 m written as 0.004700 km still has four significant figures. Reason (R): A mere change of units cannot change the number of significant figures in a measurement.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false

-
5.Which are limitations of dimensional analysis? (I) cannot obtain dimensionless constants; (II) cannot distinguish quantities with the same dimensions; (III) tests dimensional validity, not the exact relationship.
