Answer:
True
Explanation:Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.
Explanation:
total answer is 119 km
this is the answer for the question
Answer:
Explanation:
The magnitude of the electrostatic force between two charges is given by Coulomb's law:
where:
is the Coulomb's constant
are the two charges
r is the separation between the two charges
In this problem, at the beginning we have:
is the first charge
is the second charge
r is their initial separation
So the initial force is
Later, we have:
qA is doubled and r is doubled
This means that:
is the new charge
is the new separation
So the new force is:
because we will know more about out solar system
