1) On your first example; What is the second key?
A minor.
The V chord of A minor is E major (not E minor).
This is fundamental stuff! The minor "key" employs the "harmonic minor" V chord, which is how it differs from aeolian mode, or natural minor.
This is the conventional minor key V-i cadence, and you definitely need to understand this before you dig into modulation of any kind. Major and minor keys alike use a major V chord (usually a dom7, but it doesn't have to be).

C major and F major.

In this case, the new F major key needs a dom7 V (C7), because a plain C would just sound like the I of the previous key. The sequence C - E - F wouldn't sound like the key had changed, even if you played C - E - F - C - F. Adding the 7th (Bb) to the second C makes it clearly the V of C.
