Oblicz okres wahadła matematycznego jeżeli jego dług. L=7m, g=9,81m/2

[latex]l=7m[/latex] [latex] pi =3,14[/latex] [latex]g=9,81m/s^2[/latex] [latex]T=2 pi * sqrt{ frac{L}{g} [/latex] [latex]T=3,14*2* sqrt{ frac{7m}{9,81m/s^2} } [/latex] [latex]T=6,28* sqrt{0,71} [/latex] [latex]T= sqrt{6,28^2*0,71} [/latex] [latex]T= sqrt{39,4*0,71} [/latex] [latex]T=5,29s[/latex] Pozdrawiam kari9812 :)
