A 3rd harmonic is being produced in a tube that is open at both ends. The tube is 3 meters long and

attashe74 [19]

The frequency of the second harmonic is 880 Hz (a pitch of A5). The speed of sound through the pipe is 350 m/sec. Find the frequency of the first harmonic and the length of the pipe. The length of an air column is related mathematically to the wavelength of the wave which resonates within it.

Two very long uniform lines of charge are parallel and are separated by 0.300 m. each line of charge has charge per unit length

Alenkasestr [34]

linear charge density of system of two line charges is given as

$\lambda = 5.20 \muC/m$

now as we know that electric field due to a line charge at some distance from it is given by

$E = \frac{\lambda}{2\pi \epsilon_0 r}$

so here we will first find the electric field of first line charge at the position of other line charge

$E = \frac{5.20 * 10^{-6}}{2 \pi * 8.85 * 10^{-12}* 0.300}$

$E = 312000 N/C$

now as we know that

$F = qE$

here q = charge on the line charge system at which force is required

E = electric field on that system of charge where force is required

now we can find the charge by

$q = \lambda * L$

$q = 5.20 * 10^{-6}* 0.05 = 0.26 * 10^{-6} C$

Now using the above formula

$F = qE$

$F = 0.26 * 10^{-6} * 312000$

$F = 0.0811 N$

so force on the part of wire is F = 0.0811 N

A disk with a radius of R is oriented with its normal unit vector at an angle Q with respect to a uniform electric field. Which

beks73 [17]

As we know that electric flux is given by

$\phi = E.A$

$\phi = EAcos\theta$

so in order to increase the flux we have two options

1. By increasing the area of the disc

2. by changing the orientation of disc so the area of the disc is parallel to the electric field

so correct answer will be

<em> A. increasing the area of the disk</em>
