It has to gain three more electrons to satisfy the octet rule.
Answer:
Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape that results from the net effect of the two individual waves upon the particles of the medium.
Explanation:
Answer:
The speed of this particle is constantly .
Explanation:
Position vector of this particle at time :
.
Write as a column vector to distinguish between the components:
.
Both and are constants. Therefore, and would also be constants with respect to . Hence, and .
Differentiate (component-wise) with respect to time to find the velocity vector of this particle at time :
.
The speed (a scalar) of a particle is the magnitude of its velocity :
.
Therefore, the speed of this particle is constantly (a constant.)
