# Measurement Questions and Answers (Q&A)

This may look complicated because the volume of the sphere is shown as more than ten and less than twenty ml but using width also. In fact the question is simple because the volume of water the sphere displaces pushes up the level of water in the tube, and it can be easily seen to be 25 ml higher than the original level, before the sphere was dropped into it.

The correct answer is option C
From this triple beam balance we can determine what the scale represents.

The first beam balance shows a scale of 500.
The second beam balance shows a figure of 40g
The third beam balance shows a figure of 5.2g
The total figure = 500 + 40 + 5.2
= 545.20g
Therefore, all other options are incorrect except option C.
Hope this helps.

This is a simple observational task. You must look carefully at the pointed end of the rider to ascertain exactly at which mark it is pointing. In this case, you will see that the rider points to the slightly longer dash halfway between the five and the six.

Therefore the answer is 5.5. You are saved from counting along mark by mark by having these halfway marks made longer. When you see one of these indicated, you will know that it is a .5 answer.

I do think it is 150 because I am smart!

Option C - 5.81 is the correct answer of the reading of micrometer screw gauge in the diagram.
To get the first part of the measurement, look at the image above, you will see a number 5, this means 5.0mm.

Notice the extra line, this represents an extra 0.5mm.
5 + 0.5 = 5.5mm

To get the second part of the measurement, the number 30 on the rotating vernier scale is 0.3mm, notice an extra line after 30, this represents 0.01mm.

0.30 + 0.01 = 0.31mm

Add first and second part of the measurement to get the micrometer reading
5.5 + 0.31 = 5.81mm

The correct answer to this question is 2.6 mm. Vernier calipers were invented in 1631 by Pierre Vernier, hence the name. This instrument can measure both outside and inside dimensions, as well as depth. It is very accurate and can measure one-thousandth of an inch, as well as one-hundredth of a millimeter.

The interior dimensions it can measure include the diameter of a hole found on a piece of wood. The depth it can measure is how deep a hole goes, stepping from one end of the tunnel to another. Outside measurements using a vernier caliper can be used to measure width or length.

Why do I always get the answer 215 I always try but there is the same answer
