Magic Of One Line Division

If 25venier scale divisions coincide with 20 main scale divisions. Find least count of venier calliper. ( One main scale division = 1mm )

Which one induces cell division ?

During meiosis there is (A) one round of DNA replication and one division (B) two rounds of DNA replication and one division (C) two rounds of DNA replication and two division (D) one round of DNA replication and two division

The pitch of a screw gauge is 0.5mm and there are 50 divisions on its circular scale and one main scale division =0.5 mm. Before starting the measurement it is found that when jaws of the screw gauge are brought in contact, the zero of the circular scale lies 4 division above the reference line. when a metallic wire is placed between the jaws, five main scale divisions are clearly visible and 18^(th) division on the circular scale coincides with the reference line. the diameter of the wire is

Which one is essetntial for DNA replication and cell division

One division on the main scale has 20 equal divisions which match with 16 main scale division. The leat count of the vernier calipers is

Main scale of a screw gauge is 3mm and 42 division of circular scale of 100 divisions coincides with reference line then find the diameter of the cylinder
