measuring instruments

Limitation of the measuring instrument is an important factor. This leads to uncertainty in measurement. In order to understand this, let us assume that we want to measure the volume of the liquid with a graduated cylinder. If the volume of the liquid is mor..

Let us consider the following entries in a Students' Journal: (a) Weight of a calorimeter = 42 g (measuring instrument used is spring balance) The smallest reading the spring balance can record is 1g. There are 42 of 1 g units of measurement. Hence, there are two signi..

Which instrument would one use to measure temperature? => Scale or Measuring cup or Thermometer or None of these..

These are inherent errors of the measuring instruments and apparatus. E.g., zero error of a measuring instrument. All instrumental errors come under this category. Instrumental errors, if any, can be detected by interchanging two similar ..

Emily is suffering from fever. Which of the following instruments is used to measure the temperature of the body? => Stethoscope or One device or Thermometer..

Everything that we use in our daily life is ultimately governed by principles of physics. All gadgets we use everyday at home, bicycles and cars, all different types of machinery and instruments, work on principles of physics. Hence to understand even the elementary working of these..

It is the smallest reading that can be accurately measured while using an instrument or a devic..

No measurement is ever perfectly accurate. Even with high precision instruments some error is inevitable. There are two main types of error..

Random errors occur in all measurements. They arise when observers estimate the last figure of the reading on an instrument. These include the noise in the room or the mechanical vibrations in the room. These are called random, because they cannot be predicted. The best wa..
