Reading an Analog Scale We can use an analog balance instead of a digital balance to measure the mass of a block. (An analog balance will have a needle that is displaced in proportion to the weight of the object placed on the balance.) We now need to use our judgement to read the scale after the needle has come to rest. 12 1 point You now decide, in order to improve your measurement, to choose a scale that has markings (called "gradations") every 1 gram. You now observe the following on the display: 80 90 100 grams You can now make a judgement to the nearest 0.1 gram. What is the reading on the scale in grams? Type your answer.

An analog balance will have a needle that is displaced in proportion to the weight of the object placed on the balance.) We now need to use our judgement to read the scale after the needle has come to rest. 1 point If you want to subdivide each gradation even further, you now have a division marker every 0.1g. You might need a magnifying glass to read the scale! 80 90 100 grams It becomes impractical to continue to add more and more subdivisions. Eventually the scale becomes too small to read, even when using a Vernier scale. No matter what analogue scale you are reading, you will always need to make a judgement about what the last digit is. According to the image above, what is the reading on the scale to the nearest 0.01 gram? Type your answer... Previous Submit
