Water is flowing in a pipe with a varying cross-sectional area, and at all points, the water completely fills the pipe. at point 1, the cross-sectional area of the pipe is 7.70×10−2 m2 and the magnitude of the fluid velocity is 3.60 m/s.
a. what is the fluid speed at points in the pipe where the cross-sectional area is (a) 0.105 m and (b) 0.047m2?
b. calculate the volume of water discharged from the open end of the pipe in 1.00 hour.

In a closed system, the total energy prior to an energy transformation is the total energy after. a. equal to b. unrelated to c. greater than d. less than

Wavelength of 125 meters is moving at a speed of 10 m/s. what is it's frequency?

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.
