Answer:
ν ≈ 4.7 × 10¹⁴ Hz
General Formulas and Concepts:
<u>Chem</u>
Speed of Light = Wavelength times Frequency
Explanation:
<u>Step 1: Define</u>
λ = 6.4 × 10⁻⁷ m
<u>Step 2: Solve for ν
</u>
3.0 × 10⁸ = 6.4 × 10⁻⁷ · ν
ν = 4.6875 × 10¹⁴ Hz
<u>Step 3: Check</u>
<em>We are given 2 sig figs. Follow sig fig rules.</em>
4.6875 × 10¹⁴ Hz ≈ 4.7 × 10¹⁴ Hz
Explanation:
At convergent plate boundaries two plates are moving towards one another and different scenarios are in play.
Most importantly, at these margins the crust is being destroyed.
- At continental - continental crust margin, there is an uplift because the density of the two crust is similar and lesser than that of the mantle below.
- At continental - oceanic crust margin, subduction zones are found where the denser oceanic crust sinks beneath into the mantle.
- This is also the case with ocean - ocean convergence zone.
Some of the features found at this margin include, oceanic trenches, accretionary wedges, volcanic islands, earthquakes
The correct answer is "halogens." Fluorine, chlorine, bromine, and iodine are part of a family called halogens. In the periodic table, it is the column that is beside, left of the noble gases. <span>The name 'halogen' means 'salt-producing'.</span>
No spanish sorry? i undertdand englishh what di u mean
Fe2O3 because O has a -2 charge and Fe and +3, you want the charges to equal each other so if you have 2 Fe with +3 charge the charge becomes 6 if you have 3 O with -2 charge the charge becomes 6.
