Source if its wave length is \( 1.0 \times 10^{-9} \mathrm{~nm} \) ? \( \begin{array}{ll}\text { a. } 3.3 \times 10^{-27} \mathrm{~Hz} & \text { c. } 3.0 \times 10^{18} \mathrm{~Hz} \\ \text { b. } 3.3 \times 10^{-8} \mathrm{~Hz} & \text { d. } 3.0 \times 10^{126} \mathrm{~Hz}\end{array} \)

If you increase the frequency with which you are moving the end of a Slinky back-and-forth, how does the wavelength of the Slinky change?

Look at the electrical diagram. \begin{tabular}{l}\( V=8.6 \mathrm{~V} \) \\ \( I 1=0.3 \mathrm{~A} \) \\ \( I 2=0.5 \mathrm{~A} \) \\ \( I 3=0.2 \mathrm{~A} \) \\ Calculate the total resistance. \\ \hline 8.6 \\ \hline OK. \\ \( \begin{array}{l}V=10.6 \mathrm{~V} \\ I 1=0.9 \mathrm{~A} \\ I 2=0.3 \mathrm{~A} \\ I 3=0.3 \mathrm{~A}\end{array} \) \\ Calculate the total resistance. \\ \hline\end{tabular}
