Balance Beam Scale
Balance Beam Scale
Please get the following measurement accuracy!?
47.5 degrees Celsius on the thermometer. Cl 7.5 in a small test tube 125.5 degrees on a conveyor 500 ml. in a beaker of 0.5 seconds on a stopwatch 248.75 g. on a triple beam balance 90 cm. in a meter. 7.35 grams in a spring scale. really do not know how to get these. Please help me figure it!
Its accuracy is essentially the smallest unit of measurement device can display. For example, if your thermometer can display tenths of a degree, then its accuracy is 0.1 degrees. Some people also say that the accuracy measurement is shown by the measure itself. Normally, It would take half the last significant position in determining the precise number. So for first, 47.5 degrees the thermometer indicates that possibly can measure intervals of 0.25 degrees – The last significant position is 0.5, so half the which is 0.25. This way of finding things get interesting, because his room is 500 ml. The last position in reality is 5, so that its accuracy is 250 ml. The 0s are not significant – it would be a different story if it says 500.0 mL, in which case we can see (or imply) that the measuring device is capable of measuring of 0.05 ml, and that if this measure, there was no measure of that interval.
