Tolong ya kawanku terserah kalian mau jawab yang no. Berapa dulu yang menurut kalian mudah

6. Diket :
p Hg = 13,6 g/cm3
p3 (alkohol) = 0,8 g/cm^3
p1 (bensin) = 0,7 g/cm^3
h1 (bensin) = 2 cm
h2 (raksa) = 1 cm
h3 (alkohol) = V3 / L alas penampang kiri

P1 + P2 = P3
p1gh1/p3.g + p2gh2/p3.g = p3gh3/p3.g
p1h1/p3.g + pHg.h2/p3 = p3h3/p3
0,7.2/0,8 +  13,6.h2/0,8 = 0,8.h3/0,8
1,4/0,8 + 10,7.h2 = 1.h3
1,75 + 10,7.1 = h3
1,75 + 10,7 = ( V3/La kiri )
12,45 = (V3/La kiri)
12,45 = V3 / 3,14.(1,5)^2.1/4
12,45 = V3 / 1,8
V3 = 12,45.1,8
V3 = 22,41 cm^3

7. Diket :
d1 = 5 cm
d2 = 120 cm
W = 85000 N
Hukum Pascal
F/A1 = W/A2
F/ 1/4.3,14.(5)^2 = W/ 1/4.3,14.(120)^2
F/(5)^2 = W/(120)^2
F/25 = 85000/14400
F/25 = 5,91
F = 25.5,91
F = 147,75 N
F = gaya minimum
