State one use of a screw gauge.
The thimble of a screw gauge has 50 divisions. The spindle advances 1 mm when the screw is turned through two revolutions.
(i) What is the pitch of the screw gauge?
(ii) What is the least count of the screw gauge?
The least count of a vernier callipers is 0.01 cm and it has an error of + 0.07 cm. While measuring the radius of a sphere, the main scale reading is 2.90 cm and the 5th vernier scale division coincides with the main scale. Calculate the correct radius.
When does a vernier callipers has the negative error?
The Wavelength of a particular colour is 5400Å. Express it in nanometer and metre.
Name the measuring employed to measure the diameter of a pencil.
State whether the following statement is true or false by writing T/F against it.
The ratchet of a screw gauge is used to measure the depth of a beaker.
Consider the following case where the zero of vernier scale and the zero of the main scale are clearly seen. If L.C. of the vernier calipers is 0.01 cm, write the zero error and zero correction of the following.
