Wahadło porusza sie w ciagu 21s 7x. Oblicz T : f

[latex]T = frac{21}{7} = 3s \\f = frac{1}{T}\f = frac{1}{3} = 0,3(3) Hz [/latex] [latex]T - okres drgan \\f - czestotliowsc drgan [/latex]

[latex]dane:\t = 21 s\n = 7\szukane:\T = ?\f = ?[/latex] [latex]T = frac{t}{n} = frac{21s}{3} = 3 s[/latex] [latex]f = frac{n}{t} = frac{7}{21s} = 0,(3)s^{-1} approx0,3 Hz\\lub:\\f = frac{1}{T} = frac{1}{3s} = 0,(3) Hzapprox0,3 Hz[/latex]
