The circular scale of a micrometer has 200 divisions and pitch of 2 mm. Find the measured value of thickness of a thin sheet.
- 3.41 mm
- 6.41 mm
- 3.46 mm
- 3.51 mm
The correct answer is: 6.41 mm
Least count =
= 0.01 mm ; Reading = 3 
2 + (46-5)(0.01) = 6.41 mm

An Indian submarine is moving in “Arab Sagar” with a constant velocity. To detect enemy it sends out sonar waves which travel with velocity 1050 m/s in water. Initially the waves are getting reflected from a fixed island and the reflected waves are coming back to submarine. The frequency of reflected waves are detected by the submarine and found to be 10% greater than the sent waves.
Now an enemy ship comes in front, due to which the frequency of reflected waves detected by submarine becomes 21% greater than the sent waves. Bulk modulus of sea water should be approximately (ρwater = 1000 kg/m3)

Two identical stretched wires are vibrated together. They produce 8 beats per second. When tension in one wire is changed then the beat frequency is increased. If T1 and T2 denote the tensions in the two wires at any instant and T1 > T2 (initially) then how the change may be performed.

In the experiment for the determination of the speed of sound in air using the resonance column method, the length of the air column that resonates in the fundamental mode, with a tuning fork is 0.1 m. When this length is changed to 0.35 m, the same tuning fork resonates with the first overtone. Calculate the end correction :
