Which is evidence that a convergent boundary once existed
Vladimir79 [104]

Volcanic islands, Mountain ranges

Explanation:

A convergent margin is plate boundary in which plates comes together. There are different types of interactions that occurs around a place where plate converges.

  • An ocean-continent convergence creates a subduction zone in which the denser oceanic plate sinks beneath the less dense continental crust.
  • As the oceanic plate begins to subside, it can melt and form chains of volcanic island within the riding continents.
  • Also, where two plates of equal densities converge, none of them subsides and this leads to upbuilding.
  • The product can be seen as extensive mountain ranges on earth like the Andes and Himalayas.

A magnetic field of magnitude 0.550 T is directed parallel to the plane of a circular loop of radius 43.0 cm. A current of 5.80
Assoli18 [71]

Answer:

\mu = 3.36\times 10^{-3}\ A-m^2

Explanation:

Given that,

The magnitude of magnetic field, B = 0.55 T

The radus of the loop, r = 43 cm = 0.43 m

The current in the loop, I = 5.8 mA = 0.0058 A

We need to find the magnetic moment of the loop. It is given by the relation as follows :

\mu = AI\\\\\mu=\pi r^2\times I

Put all the values,

\mu=\pi \times (0.43)^2\times 0.0058\\\\=3.36\times 10^{-3}\ A-m^2

So, the magnetic moment of the loop is equal to3.36\times 10^{-3}\ A-m^2.

Glass has a _____________ index of refraction than air
rewona [7]

Glass has a <u>grater </u>index of refraction than air. The glass's and air's indexes of refraction will be 1.5 and 1, respectively.

<h3>What is an index of refraction?</h3>

The refractive index of a substance is a dimensionless quantity that specifies how quickly light passes through it in optics.

The index of refraction of the glass and air will be 1.5 and 1 respectively.

Hence,glass has a <u>grater </u>index of refraction than air.

To learn more about the index of refraction, refer to the link;

Which one of the following environments will sound not travel through?
Eduardwww [97]
The answer is d. Vacuum

Sound waves need a molecul to travel through. Gas , solid, annd liquid provide that medium.

But vacuum is just an empty space withour any moleculs in it.

Thats why in space, no one can hear you scream. Because it simply not physicsly possible
