D. Electronic balance is advantages to use over a beam
balance.
Answers
Answer and Explanation:
Having an accurate system for measuring the weight of objects is essential for any science lab, along with various workshops, offices and kitchens. The two major types of scientific scales are beam scales (also known as beam balances) and electronic, or digital, scales. While both types of scale perform the same function, there are also important differences between them.
Function
Both beam scales and electronic scales supply precise measurements of weight. Beam scales use a balance consisting of two platforms; one is for the object being weighed and the other is for metal or ceramic weights of a known measurement. Users add weights until they equal the weight of the object on the opposite platform, then compute the weight of the object. Electronic scales offer a digital alternative, using a single platform and an electronic sensor to display the weight of the specimen on an LCD display,
Differences
Electronic scales are among the most precise measuring devices ever crafted. Even inexpensive models are likely to offer more precise measurements than most beam scales. However, electronic scales are also sensitive to environmental factors that can cause an inaccurate reading. This is why some electronic scales use a glass or clear plastic enclosure to protect the surface of the scale and the object being weighed.
