Answer

Answer:

  1. C. Applying a light coat of oil
  2. C. Spirit level
  3. C. Depth
  4. True
  5. C. To prevent movement during reading
  6. No options provided in the question for 12.

Brief Explanations:

  1. Oil prevents rust on steel rules. Storing near a magnet can magnetize it, using as a pry - bar can damage it, and daily soap - water wash can cause rust.
  2. A slide caliper typically has jaws, a depth rod, and a lock screw, but not a spirit level.
  3. Slide calipers are used for linear measurements like length, diameter, and depth, not for voltage, weight, or conductivity.
  4. A 1 - inch gage block is commonly used for field checks on English dial calipers.
  5. The lock screw on a caliper locks the jaws in place to prevent movement while taking a reading.
