The cause of electric current in a wire is that there is electron flow due to electrical attraction and repulsion.
What is Electric current?
The rate of flow of electric charge through a point is known as electric current. The electric current is nothing but the flow of electrons in general.
Consider a space, when electrons of charge (e) is flowing through the space in a given time interval t. Then,
I = e/t
here,
I is the electric current.
Moreover, there is a flow of electrons in a wire due to a potential difference existing at the circuit. Due to that, electrons always flow from high electric potential to low electric potential.
Thus, we can conclude that the cause of electric current in a wire is that there is electron flow due to electrical attraction and repulsion.

Answer: Proximity to active volcanoes
Explanation:
When volcanoes erupt, they can generate tsunamis in the following ways:
-Parts of the volcano (some of them may be underwater) could collapse, generating a big displacement of water and resulting in a tsunami.
-The magma chamber could also collapse as it empties, also generating water displacement.
-If the volcanoes are near to the shore, debris resulting from the eruption could hit the water at fast speeds, producing big waves and eventually a tsunami.
In this case, the proximity of Palu city to active volcanoes, especially ones that are so close to the shore, increases the risk of a tsunami.
Answer:
mechanical layers of the earth
Lithosphere
-Asthenosphere
-Mesosphere
-Outer Core
-Inner Core
Chemical layers of the earth:
-Crust
-Mantle
-Core
I hope this helps :)
Answer:
Explanation:
In this case, since the charged particle moves in circular motion, the centripetal force is equivalent to the magnetic force.
I think number 1 is incorrect I believe that answer is D. Number 6 I believe would be B. The rest seem to be correct.
