Question

hypothesis: different measurement equipment’s have different quality and accuracy so this

why they give a non-identical measurement like different rulers from multiple brands give us different measurement

why please explain in detail they triple beam balance and pan balance give a different measurement for the same set of weights why?

relate it to the hypothesis

please type don't write

Answer 1

A triple beam balance is an instrument that can weigh objects, and derives its name from the three beams that carry the weights – one that reads in 100-gram increments, one that reads in 10-gram increments, and one that reads from zero to 10 grams, which can be further broken down into tenths of a gram.

A pan balance also called as double pan balance, is a scale that acts like a see-saw and gets its name from the two pans or balances on either side of a fulcrum.

The triple beam balance has three beams, while the double beam only has two. Additionally, the triple beam balance has only one pan and the double beam has two.

As you can note from the above, both the balances have different least counts. Least count of any measuring device, is the least possible measurement that can be made using that device. Thus different measuring equipmetns have different accuracy,

Thus for the same set of weights, these two instruments show different readings.

The triple beam balance is a very accurate instrument and can measure within a tenth of a gram. However, the double beam is only as accurate as the smallest weight being used. For example; if the smallest weight you have is a 5-gram weight, then you can only estimate the weight of an object to the nearest 5 grams.
