For an atom to achieve a stable electron configuration, it needs 8 valence electrons. Since this atom has 6 valence electrons, it needs 2 more to achieve a stable electron configuration.
8-6=2
The source of the earth's magnetic field is found in the ;LIQUID MAGNETIZED IRON IN THE CORE OF THE EARTH. The earth's magnetic field is believed to be generated very deep down in the earth's core as a result of molten iron which it contains.
Answer:
C. Newton's First Law of Motion
Explanation:
As the car comes to an abrupt stop, the body is still moving forward, and is moved back by the seatbelt, an outside force. If not for the seatbelt, the body would continue forward until acted on by the car itself, or thrown out of the car.
To show motion on a graph you draw the path of where the object has gone
The speed of a sound wave does not depend on the frequency of the wave, but only on the properties of the medium.
Since we are in the same concert all, the medium of propagation is still the same (the air), so it has not changed; therefore, the speed of the sound wave has not changed, and it is still 344 m/s.
So, the correct answer is "344 m/s".
