Whenever a musician plays a guitar, they pluck one of the guitar strings to produce a standing wave in the string. Then pinch do
UkoKoshka [18]

Answer:

It's due to the distance from either ends of strings origin...

Explanation:

As we know that waves behave moving in a flow from one side to another side and this gives a prospective of motion. Suppose a wave is pinched from the near one end of a guitar then due to the distortion created by the point of tie of strings the wave super imposes and moves with a velocity v and produces a wave frequency f. as we the pinching go down to the center the wave stabilizes itself to a stationary origin right at the center and the frequency then changes accordingly as moving down on the string.

A very long half-cylinder of radius r carries a total current is uniformly distributed across the circumference. Determine the m
Rufina [12.5K]

The magnetic field along the central axis of the cylinder will be <em>determined </em>using the formula given that all parameters are known

dBz=\frac{uoR^2di}{2r^3}

<h3>Magnetic field </h3>

Generally, A magnetic field is also referred to as a vector field that shows the magnetic presence on electric charges and magnetic materials.

The formula for magnetic field  is

Where

u=4\pi*10^{-7H/M}

Therefore, the magnetic field along the central axis of the cylinder will be determined using the formula given that all parameters are known

A solid sphere has a temperature of 614 K. The sphere is melted down and recast into a cube that has the same emissivity and emi
krok68 [10]

Answer:581.87 K

Explanation:

Given

Sphere is melted to form a square

Let the radius of sphere be r and square has a side a

Therefore

\frac{4\pi}{3}r^3=a^3

Surface area of sphere A_s=4\pi r^2

Surface area of cube A_c=6a^2

Total emmisive remains same

Thus P=A\epsilon \sigma T^4

A_sT_s^4=A_cT_c^4

\frac{T_c^4}{T_s^4}=\frac{A_s}{A_c}

\frac{T_c^4}{T_s^4}=\frac{1}{2}\times \left ( \frac{4\pi}{3}\right )^{\frac{1}{3}}

\frac{T_c}{T_s}=\frac{1}{2^{0.25}}\times \left ( \frac{4\pi}{3}\right )^{\frac{1}{12}}

T_c=T_s\times \frac{1}{2^{0.25}}\times \left ( \frac{4\pi}{3}\right )^{\frac{1}{12}}

T_c=614\times \frac{1.12679}{1.189}

T_c=581.87 K
