Answer:

3*10⁹ + 5.3*10¹⁰ = 5.6*10¹⁰

Explanation:

The values are given as exponents:

3*10⁹ and 5.3*10¹⁰

As per the rules:

-Before adding two numbers, all exponents must be the same

-The addition takes place between the numerical portion of the numbers

- The final value is rounded off to the least places in the decimal portion of the given numbers

Therefore, the two numbers to be added are:

3*10^{9}+53*10^{9}=56*10^{9}

Rounded off the final value to 1 decimal place gives:

5.6*10¹⁰

The emission spectrum of hydrogen shows discrete, bright, colored lines. Which characteristic of the Bohr model is best supporte
natali 33 [55]
The characteristic of the Bohr model that would best support his observation is this assumption: "The energy of the electron in an orbit is proportional to its distance from the nucleus. The further the electron is from the nucleus, the more energy it has." The discrete, bright, colored lines might represent the electrons and its distance from the nucleus. The lights are caused by the energy it has.
