University physics ( Measurements ) PLEASE HELP !!!?
what are the purpose of the following formulas?
for what matter we use each one of them?
Note: ρ= density
Δρ/ρ = [(Δm∙m-1)2 + (Δh∙h-1)2 + (Δl∙l-1)2 + (Δw∙w-1)2]½ = z
Δρ/ρ = [(Δm∙m-1)2 + (ΔV∙V-1)2]½
Δρ = z∙V∙ρ
ρ = m∙(w∙l∙h)-1 Note: ((WLH = Width, Length, Height))
ρ = ρ(best) + Δρ
