Explanation Hydrogen like atoms For a hydrogen like atom the energy of any orbital is given by E = /n 2 where n is the principal quantum number ; Thus the energy of the orbital only depends on the Principal Quantum number for hydrogen like monoelectronic atoms This means 2s 2p have the same energy 3s 3p and 3d have the same energy for the

Precision It is the measure of reproducibility given a fixed value of a quantity precision is a measure of the degree of agreement within a group of measurements Precision of an instrument does not guarantees accuracy; An instrument with more significant figures has more precision; Deflection factor is reciprocal of sensitivity
The correct answer is Thermometer Key Points A thermometer is a device used for measuring temperature ; It works on the principle of thermal expansion which means that the material used in the thermometer expands or contracts depending on the temperature ; The most common type of thermometer is a mercury thermometer which consists of a glass
Measurements are always made using an instrument of some kind Rulers stopwatches weighing scales and thermometers are all measuring instruments The result of a measurement is normally in two parts a number and a unit of measurement How long is it 2 metres What is not a measurement

1 Measurement matters Measurement is an essential part of science and without measurement scien ti c models and theories can not be implemented Careful measurement with properly identi ed uncertainties can lead to a new discovery For an engineer the accurate measurement may lead to improved complex systems space
The traditional manual method for measuring takes a long time because of the number of measures and the training of the measurer who has to first learn how to take each measure which is why the objective of the software is to diminish the time employed in the taking of the data by systemizing the process
