Zad.1 Dane: Szukane: Wzór: m=200kg d=? V=5m3 Zad.2 Dane: Szukane: d=7 gramów na cm 3 m=? V=10cm3 Wzór: Zad.3 Dane: Szukane Wzór: d=1000kg na m3 V=? m=10kg Zad.4 Dane:

zad.1. Dane:  m = 200 kg V = 5 m³ szukane : d = ? [latex]d = frac{m}{V } [/latex] [latex]d = frac{200 kg}{5 m^3} = 40 frac{kg}{m^3} [/latex] zad.2. Dane: d=7 g/cm³ V=10 cm3 szukane : m [latex]d = frac{m}{V } /* V [/latex] [latex]m = d * V [/latex] [latex]m = 7 frac{g}{cm^3} *10 cm^3 = 70 g = 0,07 kg [/latex] zad.3. Dane: d =1000 kg/ m³ m =10 kg szukane V [latex]d = frac{m}{V} /* V [/latex] [latex]d * V = m /: d[/latex] [latex]V = frac{m}{d} [/latex] [latex]V = frac{10 kg }{1000 frac{kg}{m^3} } = 0,01 m^3[/latex] zad/4. Dane: Fg =10N g = 10 m/s² = 10 N/kg   Szukane : m=? [latex]F_g = m * g /:g [/latex] [latex]m = frac{F_g}{g } [/latex] [latex]m = frac{10 N }{10 frac{N}{kg } } = 1 kg [/latex] zad.5 Dane: m=70 kg g = 10 N/kg Szukane : Fg=? [latex]F_g = m * g [/latex] [latex]F_g = 70 kg * 10 frac{N}{kg } = 700 N[/latex]
