Which of the following equations best describes heat conduction through a single sheet of material? O
A.
k(T2-T)
Ø
B
k(T1+T2)
L
e
c.
k(TT)(TTT)
D
k(T-12)
L

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.

i'm pretty sure its b i might be wrong though!

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
