Answer: 
The linear momentum 
is given by the following equation:
(1)
Where 
is the mass and 
the velocity.
On the other hand, the kinetic energy 
is given by:
(2)
Which is the same as:
Now, if we double the kinetic energy, equation (2) changes to:
(3)
So, if we want to obtain the kinetic energy as shown in (3), the only option that works is increasing momentum by a factor of or 
:
Applying this in (2):
>>>As we can see, this equation is the same as equation (3)
Therefore, the correct answer is B
Answer: It represents the whole distance traveled. Hope this helps!
Explanation:
Answer:
The right approach will be Option C "Group 12".
Explanation:
- A table that further arranges the chemical components in addition to expanding the electron configuration. Elements possessing identical characteristics are positioned in almost the same section (column or group), although elements in almost the same row become positioned with a similar amount of electron spheres.
- Group 12 components therefore partially replaced (n − 1)d subshells, and therefore aren't metals, technically accurate. However, although much their chemistry seems to be comparable to something like the components throughout the d block which includes establishing themselves.
Some other options in question are not relevant to something like the given scenario. Because then the option here is just the right one.
