The lowest note on a piano is 27.5 Hz. To fit inside the piano,
the string for the low note can't be
longer than 1.20 m. If it takes the
full length, what is the speed of
the wave in the string?
(Unit = m/s)

Which of the following is not a part of a wave? question 2 options: a: frequency b: refraction c: wavelength d: amplitude (whoever answers correctly first gets brainiest! ) ~kayla

Which is special about a dc circuit ? a. it has both series and parallel components b. it has only series or only parallel components c. charge moves in a single direction d. charge moves back and forth quickly

4. now look at the green lines you created by connecting the three boiling point data points and the three melting point data points. for each of these lines, describe any trends you see. 5. locate the elements on your periodic table that you circled in green on your graph. what term or description would you use to identify these elements with respect to the periodic table? 7. using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers.
