Solve the problem.
-In an electric circuit, the electromotive force is defined as $V = \cos 2 \pi t$, where $t$ is time in seconds. Solve the equation for $\mathrm { t }$.
A) $t = \frac { 1 } { 2 \pi } \cos V$
B) $t = 2 \pi \cos V$
C) $t = \frac { 1 } { 2 \pi } \arccos V$
D) $t = 2 \pi \arccos V$

To solve for $t$, we need to isolate $t$ on one side of the equation. Given $V = \cos 2 \pi t$, we take the inverse cosine ($\arccos$) of both sides to get $2 \pi t = \arccos V$. Then, divide both sides by $2 \pi$ to solve for $t$, resulting in $t = \frac { 1 } { 2 \pi } \arccos V$.
