10. gambar kurang jelas, mungkin gini :
a.
SU = 3 mm
SN = 0,32 mm
Hasil = 3 + 0,32 = 3,32 mm
b.
3 + ?
c.
0 + 0,07 = 0,07 mm
d.
3 + 0 = 3 mm
11.
ρ = m/V
V = 85 - 60 = 25 ml
m = 60 g
ρ = 60/25 = 2,4 g/ml
12.
s = 660 m
v = 330 m/s
v = s/t
t = s/v
t = 660/330 = 2 s
waktu suara pergi pulang = 2 x 2 = 4 detik baru terdengar lagi
*maaf klo tdk benar
*biasakan cari jawaban lain utk dibandingkan
Penjelasan:
" Life is not a problem to be solved but a reality to be experienced! "
