Đổi \(-60^o=-\dfrac{\pi}{3}\)

\(x=6sin\left(10\pi t+\pi\right)=6cos\left(10\pi t+\dfrac{\pi}{2}\right)\)

Pha dao động \(10\pi t+\dfrac{\pi}{2}=-\dfrac{\pi}{3}\Leftrightarrow t=-\dfrac{1}{12}s\Rightarrow x=6\left(cm\right)\)

\(W_t=9\cdot W_đ\Rightarrow W_đ=\dfrac{1}{9}\cdot W_t\)

Để \(W_đ=\dfrac{1}{9}W_t\Rightarrow x=\pm\dfrac{A}{\sqrt{\dfrac{1}{9}+1}}=\pm\dfrac{3\sqrt{10}}{10}A\)

a) \(R_{234}=\left(\dfrac{1}{R_2}+\dfrac{1}{R_3}+\dfrac{1}{R_4}\right)^{-1}=8\left(\Omega\right)\)

\(R_{tđ}=4+8=12\left(\Omega\right)\)

\(\Rightarrow U_2=I_2\cdot R_2=0,2\cdot32=6,4\left(V\right)\)

b) \(I_1=I_{234}=\dfrac{U_2}{R_{234}}=\dfrac{6,4}{8}=0,8A\)
