The density of the wood to model the continental crust and the oceanic crust.

Answer to Problem 4PEB
The wood having density 0.81 g/cm3 would be appropriate to model continental crust. Wood having density 0.90 g/cm3 is required to model oceanic crust.
Explanation of Solution
Write the equation that can be used to calculate the density of the wood.
After multiplying
Here,
Conclusion:
i) Continental crust
Substitute
Therefore, the density of wood should be
ii) Oceanic crust
Substitute
Therefore, the density of wood should be

- Four capacitors are connected as shown in the figure below. (Let C = 12.0 µF.) A circuit consists of four capacitors. It begins at point a before the wire splits in two directions. On the upper split, there is a capacitor C followed by a 3.00 µF capacitor. On the lower split, there is a 6.00 µF capacitor. The two splits reconnect and are followed by a 20.0 µF capacitor, which is then followed by point b.

- How, Please type the whole transcript correctly using comma and periods as needed. I have uploaded the picture of a video on YouTube. Thanks,arrow_forwardA spectra is a graph that has amplitude on the Y-axis and frequency on the X-axis. A harmonic spectra simply draws a vertical line at each frequency that a harmonic would be produced. The height of the line indicates the amplitude at which that harmonic would be produced. If the Fo of a sound is 125 Hz, please sketch a spectra (amplitude on the Y axis, frequency on the X axis) of the harmonic series up to the 4th harmonic. Include actual values on Y and X axis.arrow_forwardSketch a sign wave depicting 3 seconds of wave activity for a 5 Hz tone.arrow_forward
