Molecules of gas in the air absorb light of shorter wavelengths in the range of 450-495nm is an example of quantitative data.
Quantitative data is defined as the data that can be counts in number or can be measured in numbers. There are two main types of quantitative data : discreate data and the continuous data. examples are age , date, distance , weight etc. so, the countable and measurable quantities in numbers is quantitative data. Wavelength here is measured in numbers . so, wavelength is the quantitative data.
Thus, Molecules of gas in the air absorb light of shorter wavelengths in the range of 450-495nm is an example of quantitative data.

Scientists use scientific notation to communicate extremely small measurements. Hence, option A is correct.
<h3>What scientific notation?</h3>
Scientific notation is a way of writing very large or very small numbers.
Scientists use scientific notation to represent very small or very large numbers because this notation increases the
- accuracy of measured quantities.
- convenience in using the numbers.
- the number of significant figures.
- precision of measurements.
Hence, option A is correct.

Answer:
potential energy (im positive that its right)
Explanation:
The products of nuclear fusion are by far heavier than the reactants. Nuclear fusion is the combination of small atomic nuclei into larger ones.This reaction is accompanied with the release of a large amount of energy:
²₁H + ²₁H → ⁴₂He + energy
In the above reaction,
two hydrogen atoms fuse and produce a heavier helium atom which differs from the combining atoms.
