Those dots represent the valence electrons of the element. The only elements with 6 valence electrons are oxygen, sulfur, selenium, and..... so on. SO the answer to your question is B, tellurium(Te).
Initial velocity, u = 40 m/s
Final velocity, v = ?
t = 2s
g ≈ 9.8 m/s²
v = u + gt. Since it is a free fall, acceleration due to gravity, g
v = 40 + 9.8*2
<span>v = 59.6 m/s</span>
The history of life in the geologic past as indicated by the imprints or remains of living thing is called FOSSIL RECORD.<span> It is the evolution that unfolded over trillion of years as natural and environmental interacts based on the natural selection. The fossil record is among the most popular evidences of evolution. It shows the way of living, the type of people, the survival struggles of the ancient people in the old times. All these types of remains are recorded that makes up the fossil record. </span>
