1. Responda as questões sobre quantização de carga a) Um corpo possui carga elétrica de \( 1,2 \times 10^{-6} \mathrm{C} \). Sabendo-se que a carga elétrica fundamental é \( 1,6 \times 10^{-19} \mathrm{C} \), encontre quantos elétrons estão em falta nesse corpo. b) A carga elétrica de um corpo é sempre múltipla da carga fundamental, de um único elétron, cujo módulo é igual a \( 1,6 \cdot 10^{-19} \mathrm{C} \). Se um corpo perder \( 2,0.10^{11} \) elétrons, então, qual sua carga elétrica total?

If you increase the speed of a wave on a Slinky by increasing the tension, but keep the same frequency of back-and-forth motion, how does the wavelength change? Multiple Choice

\begin{tabular}{l} Look at the electrical diagram. \\ \( I_{R 1}=0.7 \mathrm{~A} \) \\ \( R 1=3.8 \Omega \) \\ Calculate the source voltage. \\ \hline 2.66 \\ \hline OK. \\ \begin{tabular}{l}\( I_{R 1}=0.8 \mathrm{~A} \) \\ \( R 1=4.7 \Omega \) \\ Calculate the source voltage. \\ \hline\end{tabular} \\ \hline\end{tabular}

A wave can be propagated on a blanket by holding adjacent comers in your hands and moving the end of the blanket up and down. What type of wave is this? Multiple Choice longitudinal

At sporting events the crowd sometimes generates a "wave" that propagates around the stadium. What type of wave is this?

A slowly moving engine bumps into a string of coupled railroad cars standing on a siding. A wave pulse is transmitted down the string of cars as each one bumps into the next one. What type of wave is this? Multiple Choice a mix of transverse anditudinal
