Answer:

Explanation:
The magnetic dipole moment of a circular coil with a current is given by
where
I is the current in the coil
is the area enclosed by the coil, where
is the radius of the coil
So the magnetic dipole moment can be rewritten as
(1)
Here we can assume that the magnetic dipole moment of Earth is produced by charges flowing in Earth’s molten outer core, so by a current flowing in a circular path of radius

Here we also know that the Earth's magnetic dipole moment is

Therefore, we can re-arrange eq (1) to find the current that the charges produced:

Answer:
magnifying glass
Explanation:
makes objects bigger and smaller / used in science
Hello.
BEVs and hydrogen fuel cell vehicles are a more promising transportation technology for the future because they reduce greenhouse gas emissions as well as CO2 making it more 'green.' The second question is your opinion, in mine no, they should not be required but they should at least be considering.
Have a nice day
-2/5 = 11k - k
-2/5 = 10k
-2/5/10 = k
-2/5 * 10 = k
-2/50 = k
k = -1/25.
-1/25 - 2/5 = 11k is true.
