which observation about the Mid-Atlantic Ridge region provides the best evidence of the seafloor has been spreading over for mil
Kitty [74]

Magnetic stripes on the sea floor

Explanation:

The observation of magnetic stripes patterns at the region of the Mid-Atlantic Ridge galvanized the evidence that sea floor spreading has been on for several millions of years.

  • Geomagnetic field of the earth is similar to that of bar magnet having the north and south pole.
  • It originates from the movement of iron-nickel within the outer core.
  • This geomagnetic field causes the magnetization of magnetic minerals in rock.
  • When freshly formed magma is brought to the surface at the mid oceanic ridge area, the prevailing magnetic field causes the magnetic minerals in the magma to cool in such a way that they align their domains to that of the field.
  • The magnetic field of the earth can reverse and take different geometry. Sometimes, its intensity is very strong and at other times it is weak.
  • The magnetic minerals in melts bear these records.
  • As new materials are brought up, they get magnetized.

The main purpose of the turbine in the turbojet engine is to
AnnZ [28]
<span>The correct answer is A. drive the compressor. It's not D because the compressor compresses it, not the turbine. The temperature and the velocity of gasses are unrelated to this. There are in fact two turbines, and the first one gets power from exhaustion, which is then used to power to turbine in the turbojet that is used to drive the compressor. This is how turbojets commonly work.</span>

Two train whistles have identical frequencies of 1.64 102 Hz. When one train is at rest in the station and the other is moving n
Amiraneli [1.4K]

Answer:

Vs = 6.73 m/s or Vs = 16.3 m/s

Explanation:

frequency of the trains whistle (f) = 1.64 x 10^{2} Hz = 164 Hz

frequency of beats heard = 4 beats/s = 4 Hz

velocity of the stationary train (Vr) = 0

velocity of sound in air (V) = 343 m/s

velocity of the moving train (Vs) = ?

we can get the velocity of the moving train from the formula below

Fn = f x \frac{V + Vr}{V - Vs} ...equation 1

where Fn = net frequency

  • case one - assuming the train is approaching the station Fn =  164 + 4 = 168 Hz

substituting the known values into equation 1

168 =  164 x \frac{343 + 0}{343 - Vs}

1.02 = \frac{343 + 0}{343 - Vs}

Vs = 343 - \frac{343 + 0}{1.02}

Vs = 6.73 m/s

  • case two - assuming the train is leaving the station Fn =  164 - 4 = 160 Hz

substituting the known values into equation 1

168 =  160 x \frac{343 + 0}{343 - Vs}

1.05 = \frac{343 + 0}{343 - Vs}

Vs = 343 - \frac{343 + 0}{1.05}

Vs = 16.3 m/s
