Explain mantle convection.

Physics
1 answer:
inysia [295]2 years ago
7 0

Answer:

Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle.

Some springs are wound with the wire under torsion, so that they are naturally tightly compressed. The plot of extension vs. app
ANEK [815]

The "unstretched length" is shorter than the actual unloaded length because the load applied to the material caused the extension of the material thereby increasing its length.

<h3>Hooke's law</h3>

Hooke's law states that the force applied to an elastic material is directly proportional to the extension of the elastic material.

F = kx

where;

  • F is the applied force
  • k is the spring constant
  • x is the extension

Thus, we can conclude that, the "unstretched length" is shorter than the actual unloaded length because the load applied to the material caused extension of the material thereby increasing the length of the material.

A planet is 15 light years from earth. At which of the following speeds will the crew of a spaceship complete the trip to the pl
Svetradugi [14.3K]

Answer:

option c) 0.88c is the correct answer

Explanation:

using the Lorrentz equation we have

t=\frac{d}{v}\sqrt{1-(\frac{v}{c})^2}

where,

t = time taken to cover the distance

d = Distance

v = velocity

c = speed of light

given

d = 15 light years

Now,

8years=\frac{15years\times c}{v}\sqrt{1-(\frac{v}{c})^2}

or

(\frac{v}{c})^2\times (\frac{8}{15})^2=1-(\frac{v}{c})^2

or

(\frac{v}{c})^2\times 0.284=1-(\frac{v}{c})^2

or

(\frac{v}{c})^2\times 0.284 + (\frac{v}{c})^2 =1

or

(1.284\times \frac{v}{c})^2 =1

or

(\frac{v}{c}) =\sqrt{\frac{1}{0.284}}

or

v=0.88c
