Tolong jawab pke cara.... Question from @LordFR

hendrisyafa 10. $\frac{1}{f} = \frac{1}{So}+ \frac{1}{Si}$

R = 2f --> f = 1/2 R

$\frac{1}{ \frac{1}{2}R } = \frac{1}{So}+ \frac{1}{Si}$

   $\frac{2}{ R} = \frac{1}{So}+ \frac{1}{Si}$ --> B

b. $\frac{1}{f} = \frac{1}{So}+ \frac{1}{Si}$

   $\frac{1}{f} = \frac{Si+So}{Si.So}$

   $f= \frac{So.Si}{So+Si}$ --> B

c. $\frac{1}{So}= \frac{1}{f}- \frac{1}{Si}$

   $\frac{1}{So}= \frac{Si-f}{Si.f}$

   $So= \frac{Si. f}{Si-f}$ --> B


d. $\frac{1}{Si}= \frac{1}{f}- \frac{1}{So}$

   $\frac{1}{Si}= \frac{So-f}{So.f}$

$Si = \frac{So.f}{So-f}$ --> S

11. $F= k. \frac{Q1.Q2}{r^{2}}$

F ~ 1/r² ( F berbanding terbalik dgn kuadrat jarak pisah muatan)

sehingga

   $F1 : F2= \frac{1}{R1^{2} } : \frac{1}{R2^{2}}$

   $F1 : F2= R2^{2} : R1^{2}$

$F1:F2 = (4R1)^{2}:R1^{2}$

   $F1:F2= 16R1^{2}:R1^{2}$

$F1:F2=16:1$

$F2= \frac{1}{16}F1$

atau SMART

$F2= \frac{1}{r^{2}}F1= \frac{1}{4^{2}}F1= \frac{1}{16}F1$

izzaTizza 10.
A.f = R/2
1/f = 1/So + 1/Si
2/R = 1/So + 1/Si

B.1/f = (Si+So)/(SoxSi)
f = (SoxSi)/(So+Si)

C. f = (SoxSi)/(So+Si)
f (So+Si)=SoxSi
fSo +fSi = SoxSi
fSi = (SoxSi)-fSo
fSi = So(Si - f)
So = fSi /(Si - f)

11. F = kQ1Q2/R^2
Dari persamaan ini diketahui F~1/R^2
F1/F2 = R2^2/R1^2
F1/F2 = (4R1)^2/R1^2
F1/F2 = 16R1^2/R1^2
F1/F2 = 16/1
F2 = 1/16 F1

12.
Ggl = 2.4V
Ri = 0.1ohm
R = 0.5ohm
R tot = 0.1 + 0.5 = 0.6ohm
I = GGL /R = 2.4/0.6 = 4A

Vrangkaian = IxR = 4x0.5 = 2V

VSumber = IxRi = 4x0.1= 0.4V
