(a)
The orientation of sheet for maximum magnitude of magnetic flux through it.
(a)

Explanation of Solution
Introduction
The magnetic flux can be defined as the number of magnetic field lines that pass through a closed surface.
The mathematical expression for the magnetic flux is given by,
The magnetic equator is a line on the surface of Earth on which magnetic field of Earth is horizontal. At the magnetic equator, for the maximum magnitude of the magnetic flux the orientation of the flat sheet should be in such a way that the normal to the sheet is vertical in orientation.
Conclusion:
Therefore, the orientation of sheet is in such a way that normal to the sheet is vertical.
(b)
The orientation of the flat sheet.
(b)

Explanation of Solution
Introduction:
The magnetic flux can be defined as the number of magnetic field lines that pass through a closed surface.
The mathematical expression for the magnetic flux is given by,
At the magnetic equator, for the minimum magnitude of the magnetic flux the orientation of the flat sheet should be in such a way that the plane of the paper is perpendicular to the surface of the Earth at that location.
Conclusion:
Therefore, the orientation of the sheet is perpendicular to the surface of the Earth at that location.

- A 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_forwardSketch a sine wave depicting 3 seconds of wave activity for a 5 Hz tone.arrow_forward
