1) If a sound with the same amplitude and energy is propagated at a source, predict through which medium the sound will travel t
Lady bird [3.3K]

Answer:

denser media the speed is greater

Explanation:

The speed of sound is given by the relation

  v= \sqrt{\frac{B}{\rho} }

where B is the volume modulus and ρ the density of the medium

When analyzing the previous expression, the amplitude of the sound depends on the energy carried by the wave.

Wave speed, is given by the relationship between two magnitudes, we analyze their values ​​for different media. The volume modulus for gases has values ​​of the order of 10⁵ Pa, for liquids of the order of 10⁹ Pa and for solids of 10¹⁰ to 10¹¹ Pa, while the density has values ​​of the order of 10⁻¹ to 10⁰ kg / m³ for gases for liquids 10³ kg / m³ and for solids of the order of 10³ to 10⁴ kg / m³

 

let's find the order of magnitude of the speed of sound

Gases

     v =√ 10⁵/10⁰ = 300 m / s

liquids

     v =√ 10⁹/10³ = 1000 m / s

solid

     v = √ 10¹¹/ 10⁴ = 3000 m / s

We can see that in denser media the speed is greater

What happens to the mantle and the plates at each type of plate boundary? How can you use the materials to show what happens? *
Lilit [14]

Answer:

Explanation:

A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create new oceanic crust.

A particle with negative charge q and mass m = 2.65×10−15 kg is traveling through a region containing a uniform magnetic field B
Norma-Jean [14]

Answer:

q = 2,95 10-6 C

Explanation:

The magnetic force on a particle is described by the equation

      F = q v x B

Where bold indicate vectors

Let's make the vector product

      vxB =\left[\begin{array}{ccc}i&j&k\\-3&4&12\\0&0&-0.13\end{array}\right]

                     

      v x B = 1.20 106 [i ^ (4 0.130) - j ^ (3 0.130)]

      vx B = 1.20 106 [0.52 i ^ - 0.39j ^]

As they give us the force module, let's use Pythagoras' theorem,

     |v xB | =1.20 10⁶ √( 0.52² + 0.39²)

    |v x B| = 1.20 10⁶ 0.65

     v xB = 0.78 10⁶

Let's replace and calculate

    2.30 = q 0.78 10⁶

    q = 2.3 / 0.78 106

    q = 2,95 10-6 C
