3. As part of an engineering team at Space-X designing microcircuitry to control rocket launch angle, you must assess the power budget needed to operate 4 fin-control systems. Each system requires 0.16 micro Amperes for circuits with 3.4 milli-Ohms of resistance. How much total voltage is needed to supply these circuits?

What's with these goofy questions?  There's no practical electronics that's doing anything with a minuscule current of .16 microamps through a dead short of 3.4 milliohms.

Anyway,

V = IR = .16 × 10⁻⁶ × 3.4 × 10⁻³ = 5.4 × 10⁻¹⁰

 5.4 × 10⁻¹⁰ volts

Finally a use for dead batteries.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
