Question

What are the common tools scientists use to measure length and mass ?

Answer 1

Hint: Making accurate phenomenon findings is one of the keys to success in lab sciences like chemistry, physics, and biology. The metric system or SI units is used to measure a wide range of quantities, including length, mass, volume, and temperature. It is the primary system of measurement.

Complete answer:
One of the first measurements to be standardised was the length, which differed from country to country and also over long periods. Meter is the SI unit of measurement for measuring the length of an item. A Meter scale is used to determine the length. An object's mass refers to the volume of matter it contains. Since weight varies depending on the influence of gravity, measuring mass does not necessarily equal measuring weight.

The mass of an object, on the other hand, remains constant regardless of its location. The amount of matter is unchanged. To determine the mass of an object, scientists use a balance. The triple beam balance is an example of a balance. The unit of measurement for mass is Kilogram, and it is based on the metric system.

Therefore, the meter scale is a common tool used by scientists to measure length, and the triple beam balance is used to measure mass.

Note: We could use a few more advanced instruments these days, such as micrometers or analytical balances. Remember that the metric system, which includes the seven base units for length, mass, time, temperature, electric current, luminosity, and quantity, is the most extensive and accurate system for measuring the Universe that humans have created. SI unit of length is Meter, and Kilogram is the SI unit of mass.
