Question

Tuliskan rumus dimensi dari besaran besaran berikut
a.massa jenis
b.tekanan
c.energi
d.impuls

Answer 1

A. massa jenis
=kg/m3 = [M] : [L]3
=[M] [L]-3
=[ML-3]

b. Tekanan
=F/A
=[M] [L] [T-3]

c. energi, = ?

d. impuls
= kgm/s
=[MLT-1]

Semoga benar...

Answer 2

M.jenis =kg.ms^-1 =[M][L][T^-1]
tknan=kg.ms^-2.m = [M][L^2][T^-2]
