Answer:

a) 906.5\ N .m^2/C

b) 0\ N . m^2/C

c) 742.5\ N . m^2/C

Explanation:

Area of the plane is,

a) The plane is parallel to the yz-plane.

A = (0.350)(0.700)\\= 0.245\ m^2\\\phi_{E} = EA \cos \theta \\= (3.70 \times 10^3)(0.245) \cos0^{\circ}\\\phi_{E} = 906.5\ Nm^2/C\\

b) The plane is parallel to the x-axis, the normal line of the area in at a right angle

\theta = 90^{\circ}\\  \phi_{E} = EA \cos \theta\\  \phi_{E} = (3.70 \times 10^3)(0.245) \cos 90^{\circ}\\  \phi_{E} = 0\ N . m^2/C\\

c) The plane contains the y-axis, and its normal makes an angle of 35.0^{\circ} with the x-axis 35.0^{\circ}

\phi_{E} = EA \cos \theta\\  \phi_{E} = (3.70 \times 10^3)(0.245) \cos 35^{\circ}\\  \phi_{E} = 742.5\ N . m^2/C

Answer:

a)906.5 Nm^2/C

b) 0

c) 742.56132 N•m^2/C

Explanation:

a) The plane is parallel to the yz-plane.

We know that

flux ∅= EAcosθ

3.7×1000×0.350×0.700=906.5 N•m^2/C

(b) The plane is parallel to the xy-plane.

here theta = 90 degree

therefore,

0  N•m^2/C

(c) The plane contains the y-axis, and its normal makes an angle of 35.0° with the x-axis.

therefore, applying the flux formula we get

3.7×1000×0.3500×0.700×cos35°= 742.56132 N•m^2/C

It will be unaffected by the magnet because it has no magnetic field. If you were to maybe have electricity going through it is the only way it would have anything to do with the magnet.

Waves diffract the most when their wavelength is
djverab [1.8K]
<h2>Answer: about the same size of the gap  or slit</h2>

Diffraction happens when a wave (mechanical or electromagnetic wave, in fact, any wave) meets an obstacle or a slit .When this occurs, the wave bends around the corners of the obstacle or passes through the opening of the slit that acts as an obstacle, forming multiple patterns with the shape of the aperture of the slit.

Note that the principal condition for the occurrence of this phenomena is that the obstacle must be comparable in size (similar size) to the size of the wavelength.

In other words, when the gap (or slit) size is larger than the wavelength, the wave passes through the gap and does not spread out much on the other side, but when the gap size is equal to the wavelength, maximum diffraction occurs.

Therefore:

<h2>Waves diffract the most when their wavelength is <u>about the same size of the gap </u></h2>
