उत्तर
Final result of the calculation in an experiment = 125,347,200
When accuracy lies between 1 and 100, then the final result may be written as 1.25 × 108.

Explain the terms : Pitch .
How are they determined?
State one use of a screw gauge.
(a) A vernier scale has 20 divisions. It slides over the main scale, whose pitch is 0.5 mm. If the number of divisions on the left hand of the zero of vernier on the main scale is 38 and the 18th vernier scale division coincides with the main scale, calculate the diameter of the sphere, held in the jaws of vernier callipers.
(b) If the vernier has a negative error of 0.04 cm, calculate the corrected radius of the sphere.
The least count of a vernier callipers is 0.0025 cm and it has an error of + 0.0125 cm. While measuring the length of a cylinder, the reading on the main scale is 7.55 cm, and the 12th vernier scale division coincides with the main scale. Calculate the corrected length.
State the correction if the positive error is 7 divisions when the least count is 0.01 cm.
A measuring cylinder is filled with water up to a level of 30 ml. A solid body is immersed in it so that the level of water rises to 37 ml. Now the solid body is tied with a cork and then immersed in water so that the water level rises to 40 ml. Find the volume of the solid body and the cork.
How will you measure the least count of vernier caliper?
