The answer is C.
they run east to west which makes them parallel to the equator and they measure distances north and south.
I hope this helps.
Answer:
Note that there is little variation among the transition metals. Electronegativities generally decrease from top to bottom within a group due to the larger atomic size. Of the main group elements, fluorine has the highest electronegativity (EN = 4.0) and cesium the lowest (EN = 0.79).
It would have to be c because it is a chemical change. your welcome!!!!!
Answer:
Time, 
Explanation:
Given that,
When a high-energy proton or pion traveling near the speed of light collides with a nucleus, it may travel 
before interacting.
Let t is the time interval required for the strong interaction to occur. It will move with the speed of light. So,
So, the time interval is
