Soal ipa fisika no 6-10..... Tolong dijawab ya ka pake caranya thanks...

6.
V = 200 Volt
I = 0,5 A
t = 120 s
W = V I t
W = 200 . 0,5 . 120
W = 12.000 J
jawabannya C

7.
P = 300 W
V = 200 V
t = 2 s
W = P . t
W = 300 . 2
W = 600 Joule
jawabannya D

8.
P = 40 W
V = 200 V
jawabannya A
R = V²/P
R = 20²/40
R = 40.000/40
R = 1000 ohm
