Question

• 10,1 N/cm2 = …. N/m2 = …. kN/m2
• 7,92 km/min2 = ….m/s2 = …. mm/(ms)2

proszę o rozwiązanie z obliczeniami!!

Answer 1

1.

[tex]1 \ m = 100 \ cm\\1 \ m^{2} = 100 \ cm\times100 \ cm = 10 \ 000 \ cm^{2}\\1 \ cm^{2} = 0,0001 \ m^{2}\\\\\underline{10,1\frac{N}{cm^{2}} = \frac{10,1 \ N}{0,0001 \ m^{2}} = 101 \ 000 \ \frac{N}{m^{2}} = 101 \ 000 \ Pa = \boxed{101 \ kPa}}[/tex]

2.

[tex]1 \ km = 1000 \ m\\1 \ min^{2} = (60 \ s)^{2} = 3 \ 600 \ s^{2}\\\\\underline{7,92\frac{km}{min^{2}} = 7,92\cdot\frac{1000 \ m}{3600 \ s^{2}}=\boxed{2,2\frac{m}{s^{2}}}}[/tex]
