a.
8.0 V + I1R1 + I3R3 = 0
b.
8.0 V + I1R1 – I3R3 = 0

–8.0 V + I1R1 + I3R3 = 0
A television advertisement claiming that a product is light-years ahead of its time does not make sense because ________
A) light-years can only be used to talk about light B) it doesn't specify the number of light-years C) it uses "light-years" to talk about time, but a light-year is a unit of distance D) a light-year is an astronomically large unit, so a product could not possibly be so advanced
