Two people are talking at a distance of 3.0 m from where you are and you measure the sound intensity as 1.1 × 10-7 W/m2. Another

ioda

Answer:

$6.1875\times 10^{-8}$

Explanation:

Assuming uniform spread of sound with no significant reflections or absorption. We know that sound intensity varies $I=\frac {k}{r^{2}}$ where r is the distance

Since intensity is given then when at 3 m

$1.1\times 10^{-7}= \frac {k}{3^{2}}$

$k=3^{2}\times 1.1\times 10^{-7}= 9.9\times 10^{-7}$

Since we have the constant then at 4m

Intensity, $I= \frac {9.9\times 10^{-7}}{4^{2}}=6.1875\times 10^{-8}$

An infnitely long metal cylinder rotates about its symmetry axis with an angular velocity omega. The cylinder is charged. The ch

Klio2033 [76]

Answer:

$B = \frac{\mu_0 \rho r^2 \omega}{2}$

Explanation:

Let the position of the point where magnetic field is to be determined is at distance "r" from the axis of cylinder

so here total charge lying in this region is

$q = \rho(\pi r^2 L)$

now magnetic field inside the cylinder is given as

$B = \frac{\mu_0 N i}{L}$

here current is given as

$i = \frac{q\omega}{2\pi}$

$i = \frac{\rho (\pi r^2 L) \omega}{2\pi}$

$i = \frac{\rho r^2 L \omega}{2}$

now magnetic field is given as

$B = \frac{\mu_0 \rho r^2 L \omega}{2L}$

$B = \frac{\mu_0 \rho r^2 \omega}{2}$
