To protect her new two-wheeler, iroda bike buys a length of chain. she finds that its linear density is 0.88 lb/ft. if she wants to keep its weight below 1.9 lb, what length of chain is she allowed?

To solve for the length that is allowable, we simply take the ratio of the maximum allowable mass (1.9 lb) and the linear density. That is:

maximum allowable length =1.9 lb / (0.88 lb / ft)

maximum allowable length = 2.16 ft

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.
