Answer:
The correct answer is "reveal the structures".
Explanation:
The predicate is the part of the prayer that tells us what the subject is doing. In this prayer "The Fossils" is the subject, so we must seek the action that develops from the subject. That action is that the fossils "reveal the structures". In this way, we can find the simple predicate of this sentence.
Have a nice day!
If you increase the frequency, the photon will have more energy and can therefore transfer more electrons to the other side. As such, you will have an increased current.
Answer:
It has 4 valence electrons
Explanation:
Tin atoms have 50 electrons and 50 protons with 4 valence electrons in the outer shell.
You just have to find a conversion from amu to grams. For every 1 amu, there is 1.66×10⁻²⁴ grams. Thus,
Mass of proton = 1.0073 amu * 1.66×10⁻²⁴ grams/amu = 1.672×10⁻²⁴ grams
Since a proton is spherical in shape, the volume would be:
Volume = 1/6*πd³ = 1/6*π(1.0×10⁻¹⁵ cm)³ = 5.236×10⁻⁴⁶ cm³
Therefore, the density is equal to
Density = Mass/Volume = 1.672×10⁻²⁴ grams/5.236×10⁻⁴⁶ cm³
Density = 3.2×10²¹ g/cm³
