Question

mohon dijawab dengan cara 7 sampai 10​

Answer 1

7. A

g' = G.M/(R + 3R)²

g' = 1/16. G.M/R²

g' = 1/16. g

8. C

Massa benda = w/g

m = 180/g

gp = G.10m/(3R)²

gp = 10/9. Gm/R²

gp = 10/9.g

Berat di planet

wp = m. gp

wp = 180/g . 10/9. g

wp = 200 N

9. C

10. E

Kuadrat Perioda sebanding dgn jarak pangkat 3

T² ≈ R³

Tx² : Ty² = Rx³ : Ry³

32² : Ty² = (4/9. Ry)³ : Ry³

32² : Ty² = (4/9)³ : 1

32² : Ty² = 64/729 : 1

64/729. Ty² = 32²

Ty² = 32². 729/64

Ty² = 11664

Ty = 108 hari
