Jawaban:
1. 75000J
2. 50V
Penjelasan:
1. Diketahui = v = 10m/s
m = 1500kg
Ditanya = energi kinetik / Ek
Jawab = Ek = ½×m×v²
= ½×1500×10²
= ½×1500×100
= 75000J
2. Diketahui = Q = 4C
W = 200J
Ditanya = beda potensial / V
Jawab = V = W/Q
= 200/4
= 50V
USAHA DAN ENERGI, LISTRIK STATIS
1]
v = 10 m/s
m = 1500 kg
Ek = ... ?
Ek = ½ m v²
Ek = ½ • 1500 • 10²
Ek = 75.000 J ✔
2]
Q = 4 C
W = 200 J
V = ... ?
V = W / Q
V = 200 / 4
V = 50 V ✔
