/ - ułamek ! :D

Bardzo prosze o zrobienie tego zadania dziś !! :D

Jest o co walczyć : )

Answer 1

te sekundy zawsze są pod kreską ułamkową, Hz- obok ułamka

360/0.1min= 360/ 0,1*60s = 360/6s = 1/60s = 1/60  Hz

420/6,1min= 420/6,1*60s = 420/366s = 70/61s = 70/61  Hz

7200/h= 7200/60*60s = 7200/3600s = 2/1s = 2  Hz

360/0,5min= 360/0,5*60s = 360/30s = 12/1s = 12  Hz

150/10s= 15/1s = 15 Hz

3600/0,5h= 3600/0,5*60*60s = 3600/0,5*3600s = 1/0,5s = 2/1s = 2  Hz

720/3min= 720/3*60s =720/180s= 5/1s = 5 Hz

180/0,5h= 180/0,5*60*60s = 180/1800s = 1/10s = 1/10 Hz

900/6,5min=900/6,5*60s = 900/390s = 30/13s = 30/13  Hz

300/5min= 300/5*60s = 300/300s = 1/1s = 1 Hz

 

Answer 2

360/0.1min   =360 /6s = 60 na / 1 sekunde czyli f = 1/60 Hz

420/6,1min  = 420/ 366s T = 0,87 s  f= 1/T f= 1/0.87s = 1.15Hz

7200/h        = 2/1s   T= 1/2s     f = 2

360/0,5min  = T= 6s    f= 1/60 Hz

150/10s      =  T= 15s f= 0,067Hz

3600/0,5h   = T =2 s    f= 1/2 Hz= 0,5Hz

720/3min    = T= 4 s    f= 0,25 Hz

180/0,5h      - T= 1      f= 1 Hz

900/6,5min   f= 0,43 Hz

300/5min         = T= 1   f= 1Hz
