• Why do the pendulum clocks go slow in summer and fast in winter?
• Why is the second resonance found feebler than the first ?
• The pitch of a screw gauge is `1 mm and there are 100 divisions` on the circular scale. In measuring the diameter of a sphere there are six divisions on the linear scale and forty divisions on circular scale coincide with the reference line. Find the diameter of the sphere.
• The distance moved by the screw of a screw gauge is `2 mm` in four rotations and there are `50` divisions on its cap. When nothing is put between its jaws, `20th` divisions of circular scale coincides with reference line, and zero of linear scale is hidden from circular scale when two jaws touch each other or zero circular scale is laying above the reference line. When plate is placed between the jaws, main scale reads `2` divisions and circular scale reads `20` divisions. Thickness of plate is.A. 1.1 mmB. 1.2 mmC. 1.4 mmD. 1.5 mm
• The pitch of a screw gauge is `1 mm` and three are `100` divisions on its circular scale. When nothing is put in between its jaws, the zero of the circular scale lies `6` divisions below the reference line. When a wire a placed between the jaws, `2` linear scale divisions are clearly visible while ` 62` divisions on circular scale coincide with the reference line. Determine the diameter of the wire.
• A vernier callipers having `1` main scale division `= 0.1 cm` to have a least count of `0.02 cm`.If `n` be the number of divisions on vernier scale and `m` be the length of vernier scale, then.A. `n =10, m =0.5 cm`.B. ` n = 9, m = 0.4 cm`.C. ` n = 10,m = 0.8 cm`.D. ` n = 10, m = 0.2 cm`.
• The main scale of a vernier callipers reads `10 mm` in `10` divisions. Ten divisions of vernier scale coincide with nine divisions of the main scale. When the two jaws of the callipers touch each other, the fifth division of the vernier coincides with `9` main scale divisions and zero of the vernier is to the right of zero of main scale, when a cylinder is tighty placed between the two jaws, the zero of the vernier scale lies slighty to the left of `3.2 cm` and the fourth vernier division coincides with a main scale division. Find diameter of the cylinder.
