Oblisz f jeżeli T równa się: T= 1/4s T= 0,8s T= 3 1/3s T= 2,5s

[latex]f=frac{1}{T} \\ 1) T=frac{1}{4}s \\ f=frac{1}{frac{1}{4}s}=4Hz\\ 2)T=0,8=frac{8}{10}=frac{4}{5} \\ f=frac{1}{frac{4}{5}s}=frac{5}{4}Hz [/latex] [latex]3) T=3frac{1}{3}s=frac{10}{3}s \\ f=frac{1}{frac{10}{3}s}=frac{3}{10}Hz \\ [/latex] [latex] 4)T=2,5s\\ f=frac{1}{2,5s}=frac{4}{10} Hz =frac{2}{5}Hz[/latex]
