An organ pipe is open at both ends. It is producing sound

ozzi

To solve this problem we will apply the concepts related to the wavelength of its third harmonic.

It describes that the wavelength is equivalent to

$\lambda = \frac{2}{3}L$

Here,

$\lambda = Wavelength$

The wavelength is in turn described as a function that depends on the change of the speed as a function of the frequency, that is to say

$\lambda = \frac{v}{f}$

In this case the speed is equivalent to the speed of sound and the frequency was previously given, therefore

$\lambda = \frac{343}{262}$

$\lambda = 1.3091m$

Finally the length of the pipe would be

$L= \frac{3}{2}(1.3091)$

$L = 1.963m$

A straight wire of length 0.53 m carries a conventional current of 0.2 amperes. What is the magnitude of the magnetic field made

olga55 [171]

Explanation:

It is given that,

Length of wire, l = 0.53 m

Current, I = 0.2 A

(1.) Approximate formula:

We need to find the magnitude of the magnetic field made by the current at a location 2.0 cm from the wire, r = 2 cm = 0.02 m

The formula for magnetic field at some distance from the wire is given by :

$B=\dfrac{\mu_oI}{2\pi r}$

$B=\dfrac{4\pi \times 10^{-7}\times 0.2\ A}{2\pi \times 0.02\ m}$

B = 0.000002 T

$B=10^{-5}\ T$

(2) Exact formula:

$B=\dfrac{\mu_oI}{2\pi r}\dfrac{l}{\sqrt{l^2+4r^2} }$

$B=\dfrac{\mu_o\times 0.2\ A}{2\pi \times 0.02\ m}\times \dfrac{0.53\ m}{\sqrt{(0.53\ m)^2+4(0.02\ m)^2} }$

B = 0.00000199 T

B = 0.000002 T

Hence, this is the required solution.

Measure the length of the arrow in centimeters using correct significant figures.

Zinaida [17]

Based on the very tip of the arrow the best answer would be; 3.3cm

But i could very well be wrong and it may be 3.35, but i would say 3.3 if it just wants to the nearest 10th
