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.

What is 64 nanometers to m?

defon

$\sf Hello!$

$\sf We\: know \:that,$
$\sf 1\: meter$ = $\sf 10^{9} nm$

$\sf Then,$

$\sf Distance\: in \:m$ = $\sf Distance\: in\: nm$ × $\dfrac{\sf 1}{\sf 10^{9}}\: \sf m$

⇒ $\sf Distance\: in \:m$ = $\sf 64 × 10^{-9} \:m$

⇒ $\sf Distance\: in\: m$ = $\sf 6.4 × 10^{-8} \:m$

A projectile is launched from ground level with an initial speed of 53.7 m/s. Find the launch angle (the angle the initial veloc

Simora [160]

Answer: $\theta =75.52^{\circ}$

Explanation:

Given

initial speed of Launch $(u)$ =53.7 m/s

Range of Projectile =Maximum height of Projectile

Range is given by R $=\frac{u^2\sin 2\theta }{g}$

Maximum height is given by $H_{max}=\frac{u^2\sin ^2\theta }{2g}$

$R=H_{max}$

$\frac{u^2\sin 2\theta }{g}=\frac{u^2\sin ^2\theta }{2g}$

$\frac{u^2\sin 2\theta }{g}-\frac{u^2\sin ^2\theta }{2g}=0$

$\frac{u^2\sin \theta }{g}\cdot \left [ 2\cos \theta -\frac{1}{2}\right ]=0$

as u cannot be zero therefore

$2\cos \theta -\frac{1}{2}=0$

$\cos \theta =\frac{1}{4}$

$\theta =75.52^{\circ}$
