A quick trip down a plastic playground slide has caused a child's thin white-blond hair to begin standing straight up so that she looks like a dandelion puff. During the trip down the slide, sliding friction has
A)	transferred electric charge to her body and hair so that the like charges on her hair are repelling one another strongly.
B)	polarized her body so that she has a north pole near her head and a south pole near her feet. Her hair is following the lines of magnetic force that extend between the two poles.
C)	turned her kinetic energy into heat and given her hair a blow-dried look as a result.
D)	aligned the magnetic poles inside her body so that they all point in one direction. Her hair is levitated magnetically.
