Answer:
1 3/4 = 7/4
(7/4) / (1/8)
(7/4) * (8/1) = 56/4 = 14
D,14
Step-by-step explanation:
Answer
capacitance of capacitor.
<u>Explanation</u>
Dielectrics are non-conducting materials or insulators or bad conducting materials.Examples for dielectrics are glass, mica,Plastics etc.Dielectrics are placed inside two parallel plate capacitors. If larger the value of dielectric constant more charge can be stored.The electric field between two parallel plate capacitor is proportional to the capacitance of the capacitor.By the presence of dielectric the electric field strength reduced, so more charge can be stored.
Answer:
so......... what's the question?
Step-by-step explanation:
0.75 liter of 0.07 % is used and 0.25 liter of 0.23 % salt is used
<em><u>Solution:</u></em>
We have to 1 liter of final solution
Let "x" be the salt solution of 0.07 %
Then, (1 - x) is the salt solution of 0.23 %
Then final solution should be 1 liter of solution which contains 0.11 % salt
Thus, 0.07 % of "x" is mixed with 0.23 % of (1 - x) to make a solution 0.11 % of 1 liter
<em><u>Thus a equation is framed as:</u></em>
0.07 % of x + 0.23 % of (1 - x) = 0.11 % of 1

Thus 0.75 liter of 0.07 % is used
And,
1 - x = 1 - 0.75 = 0.25
Thus 0.25 liter of 0.23 % salt is used
The answer is A
12-(-8)x4
(-8)x4=-32
12- -32=
12+32= 44
