The distance is 30 km and the displacement is 22.4 km North East
Answer:
a
b
Explanation:
From the question we are told that
Their distance apart is
The wavelength of each source wave
Let the distance from source A where the construct interference occurred be z
Generally the path difference for constructive interference is
Now given that we are considering just the straight line (i.e points along the line connecting the two sources ) then the order of the maxima m = 0
so
=>
=>
Generally the path difference for destructive interference is
=>
=>
substituting values
=>
So
and
=>
=>
Oceanic crust is being formed it is because of the tectonic plates. Tectonic plates work because of volcanic eruption every time it will erupt the tectonic plates underground will have more pressure on magma, then below there will be a volcano thats why their is a volcano in ocean. The heat rises up then it will open, thats what we call divergent bounderies then their will be earthquakes form. Then another plate opens up and the crust is going down, it will stop if the volcano stops erupting because there is more lava left in volcano then it will go underwater and thats why oceanic crust is being formed.
