The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed.
When atoms are excited they emit light of certain wavelengths which correspond to different colors. Each element produces a unique set of spectral lines. ... Since no two elements emit the same spectral lines, elements can be identified by their line spectrum.
In scientific notation, the measurement of each figure to three significant measurements are as follows:
- 87.073 meters = 8.71 × 10⁻¹ meters
- 4.3621 × 10⁸ meters = 4.36 × 10⁸ meters
- 0.01552 meter = 1.55 × 10² meters
- 9009 meters = 9.01 × 10² meters
- 1.7777 x 10-3 m = 1.78 × 10⁻³ meters
- 629.55 meters = 6.30 × 10² meters
A significant figure is the digits in a number that is dependable and absolutely essential to express the quantity of a figure in positional notation. They are utilized to represent the appropriate degree of precision.
A scientific notation is used to express a large number in an easy decimal way multiplied by its power of 10.
From the given information, in scientific notation, and to three significant figures, we have:
- 87.073 meters = 8.71 × 10⁻¹ meters
- 4.3621 × 10⁸ meters = 4.36 × 10⁸ meters
- 0.01552 meter = 1.55 × 10² meters
- 9009 meters = 9.01 × 10² meters
- 1.7777 x 10-3 m = 1.78 × 10⁻³ meters
- 629.55 meters = 6.30 × 10² meters
Therefore, from the above concept, we can conclude that the scientific notation of each figure in three significant figures is shown in bold format.
