Which of the following bases are strong enough to deprotonate ch3ch2ch2c≡ch (pka = 25), so that equilibrium favors the products? a)ch3nhna b) cf3coona c) c6h5li d) nach2(co)n(ch3)2 e) naoh f) nh3

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

lol for the pointsss
