Answer:
nglos324 - fe3c. Iron carbide is an interstitial compound of iron and carbon with the composition Fe- 6.68 wt % Carbon. It is a brittle ceramic material and is produced in carbon steels or cast irons during pseudo-equilibrium cooling from above the eutectoid temperature (723 C).
Explanation:
<span> The energy of wave if it has a wavelength of 3.0 </span>× <span>10⁷ nm is
6.26 </span>
× 10⁻²⁴ J.
Attached below, is how to derive that answer. Note that, E= Energy, λ = wavelength, h = Plank's Constant and C= speed of light
Also, I converted the wavelength from nm to cm.
False, they recommend to help if their is an injured or strayed animal. :)
