As the frequency of a wave increases what happens to its period and wavelength if its speed stays the same

The second wave has twice the frequency of the first. You can see that the wavelength is halved when the frequency is doubled. Since v is constant, if f increases, λ must decrease, and vice versa

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.
