The number of significant figures in 0.0034060 is MCQ with Answer and Explanation

The number of significant figures in 0.0034060 is
A. 6
B. 4
C. 7
D. 5
Answer: Option D
Solution (By JKSSB Mock Tests)
Leading zeros (before first non-zero digit) are not significant. So 0.0034060: the first non-zero is 3, then 4,0,6 are significant, and the trailing zero after decimal is significant. Thus significant digits are 3,4,0,6,0 — 5 digits. Note: The last zero indicates precision. Answer is 5.

Question #1
If a body travels half the distance with speed v1 and remaining half with speed v2, average speed is
A. (v1+v2)/v1v2
B. 2v1v2/(v1+v2)
C. √(v1v2)
D. (v1+v2)/2

Correct Answer: Option B


Explanation:
Average speed = total distance / total time = d / ( (d/2)/v1 + (d/2)/v2 ) = 2v1v2/(v1+v2).
