The least count of the micrometer screw gauge described in the chapter is:

A micrometer screw gauge is more suitable than Vernier calipers for measuring:

In a micrometer screw gauge, the ratchet is used to:

If the zero of the Vernier scale is to the left of the zero of the main scale, the correction is made by:

A physical balance measures mass by:

If the zero of the Vernier scale is to the right of the zero of the main scale, the instrument shows:

In physics, weight differs from mass because weight is:
