How to magnetic stripes provide evidence of seafloor spreading

1 answer:

4 0

Magnetic stripes provide evidence of seafloor spreading due to their occurrence in the region of sea floor.

<h3>How to magnetic stripes provide evidence of seafloor spreading?</h3>

When the Earth's magnetic field reverses, a new stripe starts to form. Such magnetic patterns enable the scientist to recognize the occurrence of sea-floor spreading and provides strongest evidence for the theory of plate tectonics.

So we can conclude that magnetic stripes provide evidence of seafloor spreading due to their occurrence in the region of sea floor.

A bullet is fired into the air at an angle of 30° to the horizontal. At the same time and from the same height,

enyata [817]

Answer:

The bullet that is fired will spend longer in the air, hitting the ground after the dropped bullet.

Explanation:

Using the equation: x = x 0 + v t

If we neglect the effects of air resistance, the horizontal motion is a constant velocity.

The horizontal displacement = (velocity X cosθ)

So, the fired bullet has to travel horizontally before falling which takes a longer time compared to a bullet dropped where it is, height = 1/2 gt^2

gravity, g = 9.8 m/s2.

A stone initially moving at 8.0 m/s on a level surface comes to rest due to friction after it travels 11 m. What is the coeffici

Ivenika [448]

Answer:

Coefficient of friction will be 0.296

Explanation:

We have given initial speed of the stone u = 8 m /sec

It comes to rest so final speed v = 0 m /sec

Distance traveled before coming to rest s = 11 m

According to third equation of motion

$v^2=u^2+2as$

So $0^2=8^2+2\times a\times 11$

$a=\frac{-64}{22}=-2.90m/sec^2$

Acceleration due to gravity $g=9.8m/sec^2$

We know that acceleration is given by

$a=\mu g$

So $2.90=9.8\times \mu \\$

$\mu =\frac{2.9}{9.8}=0.296$

So coefficient of friction will be 0.296
