Answer 1

1. Paskal to 1 niuton na metr kwadratowy.    
p=F/S=N/m^2=kg*m/s^2*m^2=kg/m*s^2

2. S=0.5mm^2    1mm^2=0.000001m^2                        
0.5mm^2= 0.0000005m^2=5*10^-7m^2

3. V=3.75cm^3  1cm^3=0.000001m^3
3.75cm^3=0.00000375m^3=3.75*10^-6m^3

4. 72cm/min=72*0.01m/60s=0.012m/s

5. d=25mg/dm^3=25*0.001g/0.001m^3=25g/m^3
