tlg bantu jawab no.24&25..

24][

gaya berat = gaya angkat
m g = ½ ρ (Va² - Vb²) A
m = ½ ρ (Va² - Vb²) A / g
m = ½ • 1 • (70² - 50²) • 25 / 10
m = ½ • 1 • 120×20 • 25 / 10
m = 3000 kg ← jwb

x = 2 √(h (H-h))

Lubang A
h = 2 m
H-h = 6 m
xa = 2√12 m

Lubang B
h = 6 m
H-h = 2 m
xb = 2√12 m

xa : xb = 1 : 1 ← jwb
