Convection Currents

Explanation:

Convection currents in the mantle fuels the process of sea floor spreading. The sea floor is made up of oceanic crust that rides on the fluid asthenosphere.

  • The internal heat engine furnishes all the process that occurs within the earth's interior.
  • Heat from radioactivity, accretion when the earth was formed and friction provides a source that keeps the region of the asthenosphere molten.
  • In convection hot fluids are buoyant and light making them rise up.
  • The denser and cold layer on top is the lithosphere which sinks into the hot mantle.
  • This exchange of materials moves the sea floor above.

If a person weighs 818 N on earth and 5320 N on the surface of a nearby planet, what is the acceleration due to gravity on that
alexandr402 [8]

Answer:

g'=63.74\ m/s^2

Explanation:

It is given that,

Weight of the person on Earth, W = 818 N

Weight of a person is given by the following formula as :

W=mg

g is the acceleration due to gravity on earth

m=\dfrac{W}{g}

m=\dfrac{818\ N}{9.8\ m/s^2}

m = 83.46 kg

The mass of an object is same everywhere. It does not depend on the location.

Let W' is the weight of the person on the surface of a nearby planet, W' = 5320 N

g' is the acceleration due to gravity on that planet. So,

g'=\dfrac{W'}{m}

g'=\dfrac{5320\ N}{83.46\ kg}                

g'=63.74\ m/s^2

So, the acceleration due to gravity on that planet is 63.74\ m/s^2. Hence, this is the required solution.
