If a vernier caliper has zero reading of 0.025 cm and the caliper reads 5.565 cm what should be the correct reading?
5.565 - 0.025 = 5.54 so caliper reads 5.54 cm
If the zero reading on the vernier calipers is -0.025 cm with the reading still 5.565cm, it is 5.565 - (-0.025) = 5.565 + 0.025 = 5.59 cm
on the very top of the burette. Should start from zero to 100mL on the burette
Calibration of vernier calliper can be done using slip guages i.e. mirror finished rectangular blocks of alloy steel having different sizes & error less than one micrometer. These blocks can be joined together by sliding polished faces over each other to get disired length. Measuring this length & compairing the actual reading, we can calibrate the equipment.
No, your live (brown) cable takes the load and pulls the amps from the supply, not the neutral. Your ammeter should be clipped on the live to get a correct reading.
Take out a ruler with English and metric units. Draw one inch on a piece of paper with a pen. Now turn to the other side of the ruler and read how long your line is. It should be around 2.5 cm. If you were able to refine your measurement (say with a vernier caliper) you would see that your line would be 2.54 cm (or 25.4 mm).
This is strange, check the scale on your meter that you are reading, to make sure that you are on the correct voltage scale. If the reading is correct the suggestion would be to get an electrician to look into why there is such a voltage drop on the outlet. Don't read the voltage across the device, read the voltage from the "hot" wire to ground. That should be 120 volts. If you get that reading then there is a problem with the neutral. It could be loose or have a high resistive condition.

The vernier caliper is more accurate that a plastic ruler. That's because the caliper is designed to be used and effectively read to measure small distances. And it does this better than a "regular" ruler because it has a vernier scale built into it. It's like an "amplified ruler" attached to the device that has increased accuracy. A link is provided to the Wikipedia article on the vernier caliper and to the one on the vernier scale. Check out the pictures and skim the details. You should be able to pick it up with a bit of thought.
dafuq is this even english?!
A vernier caliper should be used to measure the diameter of a steel ball.
The zero error of a measuring instrument is the measure that it shows when it should actually be showing zero.
It depends how accurately you can read the scale. A ruler would only be accurate to 1 mm. If the caliper has a vernier scale it should be ten times better

Zero error is defined as the condition where a measuring instrument registers a reading when there should not be any reading. In case of Vernier calipers it occurs when a zero on main scale does not coincide with a zero on Vernier scale. Source: calculatored and written by Shaun Murphy
It is the value which the vernier shows when it should actually read zero. This may be because the vernier is worn.
No, it makes complete nonsense reading "you had this......... "You should have had this yesterday!"
JSGPM sizing tool....or a six inch caliper!
When the digital caliper jaws are closed without a part, the reading should be zero. This ensures that accurate measurements start from a baseline of zero before taking any measurements. If the reading is not zero when the jaws are closed, it may indicate a need for calibration or adjustment.
