Question

Tolong 8 dan 10. beserta cara yaa

Answer 1

No. 8
h = 3,75 m
v0 = 5 m/s

v ketika mencapai c :
v^2 = v0^2 + 2gh
v^2 = 5^2 + 2(10).3,75
v^2 = 25 + 75
v^2 = 100
v = 10 m/s >> jawaban b.

no. 10
ikan M
P = 1500 Pa
P = ρ.g.h
h = P/ρ.g
h = 1500/ 1000.10
h = 15/ 100
h = 15 cm

selisih tinggi
60 - 15 = 45 cm >> jawaban c

semoga bermanfaat
dan semangat buat UNnya
