Answer:

Step-by-step explanation:
We know (Ohm second law) that
where k inlcudes the rest of the parameters (material, lenght). In our situation we have k=
. The moment the diameter becomes 8mm R becomes

Answer: X=1.5
Step-by-step explanation:
Solution
Perimeter= 2(l+w)
25= 2( 3x+4 +2x+1)
25= 2(3x+2x+4+1)
25= 2(5x+5)
25= 10x+10
Now subtract 10 on both sides..
25-10= 10x+10-10
15=10x
Now divide 10 on both sides to get x
15/10= 10x/10
1.5=X
Answer
Answer:
Step-by-step explanation:
set the two equations equal to each other then solve for n
6n + 3 = 4n + 11
2n = 8
n = 4
plug n in for both equations
6(4) + 3
24 + 3 = 27
4(4) + 11
16 + 11 = 27
27 + 27 = 54
the distance is 54
