An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
The relative motion of the plates at the transform fault boundary is sliding past each other.
Transform fault boundaries are locations where two tectonic plates slide past one another horizontally. This movement can cause earthquakes due to the plates' friction and locking before they eventually slip past each other. A well-known example of a transform fault boundary is the San Andreas Fault in California.
The relative motion of the plates at the divergent boundary is moving away from each other.
Divergent boundaries occur where two tectonic plates are moving apart. This movement often results in the formation of new crust as magma rises from below the Earth's surface to fill the gap. An example of a divergent boundary is the Mid-Atlantic Ridge, where the Eurasian Plate and the North American Plate are moving apart.
The relative motion of the plates at the convergent boundary is moving toward each other.
Convergent boundaries are regions where two tectonic plates are moving toward one another. When they collide, one plate is often forced below the other, leading to mountain formation or subduction zones, depending on the types of crust involved. The Himalayas were formed from a convergent boundary between the Eurasian Plate and the Indian Plate.
At the convergent boundary between oceanic plate and continental plate, a subduction zone is formed.
In a subduction zone, the denser oceanic plate is forced beneath the lighter continental plate into the mantle, creating a trench and leading to volcanic activity. A famous subduction zone is the Peru-Chile Trench off the west coast of South America.
A mid-ocean ridge is formed by the divergence of two oceanic plates.
Mid-ocean ridges are undersea mountain ranges created by divergent tectonic plates. As the plates move apart, magma rises to fill the gap, solidifying to form new oceanic crust. These ridges are characterized by high levels of volcanic activity and play a key role in seafloor spreading. The Mid-Atlantic Ridge is a prominent example.
To find how many electrons flow through a device delivering 15.0 A for 30 seconds, we calculate the total charge, which is 450 coulombs. Then, using the charge of an electron, we find that approximately 2.81 billion billion electrons flow through the device. This calculation demonstrates the amount of electric charge in terms of the number of electrons.
