Answer:

Solution given:

a.

tn=12-n

1 st term =12-1=11

2nd term =12-2=10

3rd term=12-3=9

4th term=12-4=8

10th term=12-10=2

b.

tn=5-2n

1st term=5-2*1=3

2nd term=5-2*2=1

3rd term=5-2*3=-1

4th term=5-2*4=-3

10th term=5-2*10=-15

<u>(a) Solution</u>

T(n) = 12 - n

T(1) = 12 - 1 = 11

T(2) = 12 - 2 = 10

T(3) = 12 - 3 = 9

T(4) = 12 - 4 = 8

T(10) = 12 - 10 = 2

<u>(b) Solution</u>

T(n) = 5 - 2n

T(1) = 5 - 2 = 3

T(2) = 5 - 4 = 1

T(3) = 5 - 6 = -1

T(4) = 5 - 8 = -3

T(10) = 5 - 20 = -15

What is the reactance of a 25 mF capacitor when the applied frequency is 400 Hz?
LuckyWell [14K]

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:


X_{C}=\frac{1}{2\pi fC}   (1)



Where:


X_{C} is the Reactance in ohms (Ω)

f is the frequency of the alternating current in Hertz (Hz)

C is the Capacitance of the Capacitor in Farad (F)



In this case we have a 25 mF capacitor with an applied frequency of 400 Hz.


Note 1mF=1*10^{-3}F=0.001F



Well, with the given data we have to solve (1):


X_{C}=\frac{1}{2\pi(400Hz)(25*10^{-3}F)}    

Then:


XC=0.0159 Ω   This is the Reactance of the Capacitor
