Answer:
c.The value of T at Recording Station N would be greater than T at Recording Station S.
Explanation:
We can deduce from the information provided that the value of T at recording station N would be greater than T at recording station S.
This problem relates distance with time.
Speed = 
Distance = Speed x time
- Just like any other physical quantity, speed of a substance is directly related to time.
- The larger the time taken the farther the distance it will cover assuming the velocity is constant.
- Earthquake waves for example moves at constant speed with a unique velocity in earth materials.
- The farther the distance, the more time it will take to reach the seismic recording station.
- Since N is a distance of 200km from the epicenter, it will take a greater time and have a higher reading of T to reach the station.
It occurs in the earths lithosphere and sedimentary levels
Answer:
<em>D. One negative charge</em>
Explanation:
During the formation of a bond, if an atom gains an electron, after that it will be left with a negative charge compared to the atom before the bond is formed. This is because in these types of bonds, which are <em>ionic bonds</em>, there is a <em>transfer of electrons between atoms</em>, there will be one or more atoms that yield electrons that will be captured by another and other atoms that gain them, and the difference of charges produced by this transfer of electrons, will cause the union to occur due to the attraction between electrostatic forces.
If you have a neutral atom before joining, and it gains an electron to form a bond,<em> it will have one electron more than its initial state</em> (in the initial state, the number of protons and electrons is the same, because the atoms they are electrically neutral), so having an extra electron will make it have a negative charge, since there will be a difference between the number of protons and electrons that the atom possesses. <em>This is why the correct answer is D.
</em>
In the case of <em>response A and B</em>, <em>the atom could only remain positively charged if it loses electrons</em>, but as in this case it wins, <em>they are not correct</em>.
<em>The answer C is also not correct</em> because only one electron wins, so that it is left with two negative charges, <em>it should gain two electrons during the bond formation.</em>
Answer: En estos grupos de los elementos de transición se encuentran las llamadas tierras raras, separadas del resto de elementos de la tabla, que pertenecen al grupo IIIB y se les conoce como lantánidos y actínidos.
Answer:
As the temperature of a solid, liquid or gas increases, the particles move more rapidly.
