Karta pracy z fizyki potrzebuje na jutro.
1.
V=4 [m/s]
T=2[s]
Wzór : λ = V*T
λ=4*2=8 [m]
2.
λ=20[cm]=0,2[m]
Wzór: T=λ/V
T= 0,2/4 = 0,05[s]
b)
Wzór: f= 1/T
f = 1/0,05 = 20 [Hz]
3.
f = 2[Hz]
a)
Wzór : T = 1/f
T= 1/2 [s]
T= 1/2* 4 = 1/8[s]
1/8*2 = 1/16 [s]
c)
1/16 + 1/8 = 1/16 + 2/16 = 3/16 [s]
d)
Tu już mam problem
