Suppose you have a CPU that currently uses $140$ W of power while operating at a clock speed of $4\mathrm{.}3$ GHz at $1\mathrm{.}4$ V$.$ Assuming you wanted to reduce the power used by $30$ W $($i$.$e$.$ to $110$ W$)$ without reducing the clock speed of that CPU, how much would you need to reduce the voltage by$?$ You should assume that the capacitive load of the CPU remains unchanged for the purposes of this problem.
