Answer:
the emission of visible light by a body, caused by its high temperature.Compare luminescence.
the light produced by such an emission.
the quality of being incandescent.
The answer is: the distance between two nuclei is 2.35×10⁻¹⁰ m.
r(Na⁺) = 1.16×10⁻¹⁰ m; radius of sodium cation.
r(F⁻) = 1.9×10⁻¹⁰ m; radius of fluoride anion.
d(NaF) = r(Na⁺) + r(F⁻).
d(NaF) = 1.16×10⁻¹⁰ m + 1.9×10⁻¹⁰ m.
d(NaF) = 2.35×10⁻¹⁰ m; distance between two nuclei.
The sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice.
The answer which would have been a major difference in the ocean basins is the following one:
<span>B. Mid-ocean ridges would have been chains of mountains.
Given that the waters were lower in the past, those ridges would no longer be just mid-ocean ridges, but complete mountains due to the low levels of water around them.</span>
It a because the moons gravity pulls the water and the earths rotation moves the bump/wave
The answers are as follows:
1. TRUE, <span>The energy in a nuclear reaction comes from the transformation of mass to energy.
</span>
2. TRUE, <span>Although both fission and fusion generate energy, fusion produces much more energy than nuclear fission and produces less nuclear waste
</span>
3. TRUE, <span>In certain types of atomic bombs, a fuel, like plutonium-239, is bombarded with neutrons to create an uncontrolled nuclear reaction that splits the nuclei of the fuel.
</span>
