A, the power lines are what actually conducts (Or moves) the power.
It is NOT B or E, because wood is a terrible conductor. This is the reason it is used in homes, to make the heat, (Which is Electricity) stay inside, rather than letting it all pass through.
It is NOT C, because rubber, again, is a horrible conductor. Like wood, it is what we call an insulator, because it does not conduct heat. (or electricity) This is why we wear rubber gloves when doing electrical work.
D is an acceptable answer- Most metals are very good conductors of electricity. For example, have you ever seen a copper pan? It cooks very well, because copper is a very good conductor. Copper is a metal. This is why wire cutters have rubber handles, because the metal's conductivity could electrify the person holding it. The rubber, as I explained before, acts as a "Shield," keeping the person from getting electrocuted when cutting wires or working with electricity.
A.) Average acceleration = change in velocity/time = final velocity - initial velocity/time = 10-0/4 = 10/4 = 2.5m/s^2.
Answer:
1) They are the same line so they match equally bc they are measuring the same thing just one is more specific than the other
2) Sonar measures all depths at every possible point and maps it including all the gaps in between the 5cm apart the ocean floor is. The difference between the points could be a cliff or a smooth decline.
Answer:
Pitch, in the chemical-process industries, the black or dark brown residue obtained by distilling coal tar, wood tar, fats, fatty acids, or fatty oils.

Answer: There are 4 bonding electrons and 18 non-bonding electrons.
Explanation: To determine the number of bonding and non-bonding electrons, we will use lewis dot structure for the molecule 
Lewis dot structure is the structure in which the valence electrons around an atom is shown in a molecule. It also tells us about the number of bonds present between the two neighboring atoms.
Valence electrons of Fluorine = 7
Valence electrons of Xenon = 8
In 
Total number of valence electrons = [(1 × 8) + (2 × 7)] = 22 electrons
From, the structure attached below, the number of bonds present = 2. Hence, the bonding electrons will be = 4 electrons
- Number of non - bonding electrons = Total valence electrons - Number of bonding electrons
Number of non-bonding electrons = 22 - 4 = 18
