No.39 dan 40 kek mana??

40. m= 100 g =0,1 kg
t= 10° c
C air= 1
l es= 80

Q= mcΔt + ml
Q=0,1•1•10 + 0,1• 80
Q= 1+8=9

maaf saya ga bisa ngerjain yg 39 hehe

39][
AC = 12 V
R = 8 Ω
XL = 11 Ω
XC = 5 Ω

Penyelesaian:
Z = √(R² + (XL-Xc)²)
Z = √(8² + (11 -5)²) = √(64 + 36) = √100 = 10 Ω
I = V/Z = 12/10 = 1,2 A

m = 100 g
T = 10°C
c air = 1 kal/g°C
L es = 80 kal/g

Q1 = m c ΔT
Q1 = (100)(1)(10)
Q1 = 1.000 kal = 1 kkal

Q2 = m L
Q2 = (100)(80) = 8.000 kal = 8 kkal

Qtot = 1 + 8 
Qtot = 9 kkal
