Explanation:
Basically, its used to help absorb and transport nutrients, its also used to help blood pressure along with maintaining the right balance of fluid. These will all be helpful to our bodies and environment.
The independent variable is a variable whose variation does not depend on another.
The lines occurring in an emission spectrum are all electromagnetic waves, which means that their speed in a vacuum is
3 x 10⁸ m/s
We can use the equation,
v = fλ
which relates the velocity of a wave to the frequency and wavelength. Substituting values,
3 x 10⁸ = f * 434 x 10⁻⁹
f = 6.91 x 10¹⁴ Hz
The frequency of the wave will be 6.91 x 10¹⁴ oscillations per second.
Answer:
151.94 u
Explanation:
The atomic mass of Eu is the <em>weighted average</em> of the atomic masses of its isotopes.
We multiply the atomic mass of each isotope by a number representing its relative importance (i.e., its <em>percent abundance</em>).
The atomic masses of Eu-151 and Eu-153 are 150.92 u and 152.92 u, respectively.
Set up a table for easy calculation.
0.4803 × 150.92 u = 72.472 u
0.5197 × 152.92 u = <u> 79.473 u
</u>
TOTAL = 151.94 u
