What is the frequency of the fundamental mode of vibration of a steel piano wire stretched to a tension of 440 N? The wire is 0.
Rasek [7]

Complete Question

The complete question is shown on the first uploaded image

Answer:

Explanation:

From the question we are told that

    The tension is  T  =  440 \  N

     The length of the wire is l =  0.600 \  m

     The mass is  m  =  5.60 \ g = 0.0056 \  kg

Generally the frequency is mathematically represented as

            f  =  \frac{1}{2l}  *  \sqrt{\frac{T}{\frac{m}{l} } }

=>        f  =  \frac{1}{2 * 0.600 }  *  \sqrt{\frac{440}{\frac{0.0056}{0.600} } }

=>        f = 181 \ Hz

What are hot clouds of gaseous elements and compounds that act as nurseries for stars
Aleks04 [339]
Interstellar gas clouds are common in many galaxy, like the Orion nebulae which many young stars are being born. A typical nebula is many light years in diameter and contains enough material mass to make several thousand stars the size of our sun. The majority of the gas in nebulae consist of molecules of hydrogen and helium-but most nebulae also contain atoms of other elements. All known element in our periodic table is also being made inside this crucible of this immense hot gas. The source of the organic molecules is still a mystery. Irregularities in the density of the gas causes a net gravitational force that pull the gas molecules close together.
