Answer:
D
Explanation:
I hope this helps and have a great day
Answer:
The electric force is conservative.
Since
ΔK = −ΔU,
Kf − Ki =Ui −Uf.
We have,
Kf = 0
Ui = 0.
Thus Ki =Uf.
<u>so ,at 10 fm Uf = (2×10)−12 J.</u>
I believe the correct answer would be decreases. At constant temperature, the volume and pressure are inversely related that is when one value increases the other decreases or as one decreases the other increases. Hope this helps. Have a nice day.
Your answer is C. Both gasoline and litter would need to be physically separated from the water, because neither bonds with the water.
Answer:
10 liters of the 1% solution and 8 liters of the 10% solution she should mix to make the 5% solution.
Explanation:
Let the volume of 1% acid solution used to make the mixture = x L
So, the volume of 10% acid solution used to make the mixture = y L
Total volume of the mixture = <u>x + y = 18 L .................. (1)</u>
For 1% acid solution:
C₁ = 1% , V₁ = x L
For 10% acid solution :
C₂ = 10% , V₂ = y L
For the resultant solution of sulfuric acid:
C₃ = 5% , V₃ = 18 L
Using
C₁V₁ + C₂V₂ = C₃V₃
1×x + 10×y = 5×18
So,
<u>x + 10y = 90 .................. (2)</u>
Solving 1 and 2 we get,
<u>x = 10 L</u>
<u>y = 8 L</u>
Thus,
<u>10 liters of the 1% solution and 8 liters of the 10% solution she should mix to make the 5% solution.</u>
