Given : supply voltage = 120V;60 Hz
Inductive Reactance 
Ω
The inductive reactance is given by the formula, 
, where L is inductance and 
is given by formula, 
Apply this, we can say that, 
4mn. You are multiplying them all together.
A = L * W
(9/10) = (3/2) * W
Divide both sides (3/2)
(9/10) / (3/2) = W
(9/10) * (2/3) = W
18/30 = W
6/10 = W
W = 3/5 mile
In the figure, tx is perpendicular to line RS.this means we can use the pythagorean theorem to determine RX length the long way or simply apply the theorem that each divided triangle becomes a 30-60-90 angle. If opposite to 60 deg is equal to 6 units, then the side's length is equal to 2*6/sq rt 3 or equal to 6.93 units. The answer is half of this equal to 3.47 units.
L ≥ 5w + 4
2(L+w) ≥ 32
L+w ≥ 16
6w + 4 ≥ 16
6w ≥ 12
w ≥ 2
L ≥ 5w + 4
L ≥ 14
If L = 14 and w = 2 then the perimeter is 32.
These are the smallest dimensions that fit the criteria.
Note: If we raise the width by 1 to w = 3
then the length is at least 19. At 19 by 3 we have P = 44
Like would be appreciated!!
