How much greater is the resistivity of lead to copper? 12 times 1.2 times 0.80 times 0.080 times

The resistivity of lead is 2.2x10^-7.
For copper, it's 1.7x10^-8.
The unit is ohm-meters.

Lead's number is about 12.9 times the size of Copper's number.

Julia would be observing a. static electricity was caused by her sweater rubbing against her shirt and transferring electrons. she didn't touch anything metal, so that would cancel out b.she most likely didn't rub her sweater against her hair either, so that cancels out c.she also didn't scoot across the carpet while trying to take her sweater off, that cancels out d.so that leaves a.a. is correct.
