Question

Por favor preciso muito pra agora

Answer 1

10.

$T = 0,20s\\\lambda = 30cm = 0,3m\\\\v = \frac{\lambda}{T} = \frac{0,3}{0,2} = 1,5m/s$

c) 1,5

11.

$f = \frac{20}{60} = \frac 26Hz\\\\T = \frac{1}{f} = \frac{6}{2} = 3,0s$

a) um período de 3,0 segundos.

Answer 2

10.

\begin{gathered}T = 0,20s\\\lambda = 30cm = 0,3m\\\\v = \frac{\lambda}{T} = \frac{0,3}{0,2} = 1,5m/s\end{gathered}

T=0,20s

λ=30cm=0,3m

v=
