Answer:
it is 59
Step-by-step explanation:
Answer:
C (u=5)
B ( angle 4)
Step-by-step explanation:

If the angle above b is 54° then,
<h2>a = 54°</h2>
(Corresponding angles of a parallel line)
<h2>b = 126°</h2>
(Cause <b and 54° form a linear pair which is 180° and 180° -54° = 126°)

Answer:
Step-by-step explanation:
4^3 * 4^4 = 4^(3+4) = 4^7
4^7/4^9 = 4^(7-9)
= 4^-2 = 1/4^2
The Reactance of a Capacitor is t<u>he resistance it has when alternating current (A/C) with a specific frequency (f) passes through it. </u>This is measured in ohms (Ω) and its formula is:
(1)
Where:
is the Reactance in ohms (Ω)
is the frequency of the alternating current in Hertz (
)
is the Capacitance of the Capacitor in Farad (
)
In this case we have a 25 mF capacitor with an applied frequency of 400 Hz.
Note 
Well, with the given data we have to solve (1):
Then:
XC=0.0159 Ω This is the Reactance of the Capacitor
