The law of superposition states that in an undeformed sequence of sedimentary rocks the oldest rocks will be at the bottom while
the
youngest will be on top. Notice the word undeformed in the last sentence: that means the naturally occurring rock layers are
somehow altered, causing confusion or gaps in the geologic record. Changes to the rock strata can occur due to a variety of geologic
events. Which geologic event is INCORRECTLY identified?
es )
A)
A. Faulting due to stress and fracture.
B)
B. Folding of layers due to compression.
D. Intrusion of magma at Earth's surface
D)
C. Unconformity showing erosion and deposition

Answer:
0.125 volts
Explanation:
The induced emf can be sufficient to stimulate neuronal activity.
One such device generates a magnetic field within the brain that rises from zero to 1.5 T in 120 ms.
We need to find the induced emf within a circle of tissue of radius 1.6 mm and that is perpendicular to the direction of the field. The formula for the induced emf is given by :
Where
is magnetic flux
So,
So, the induced emf is equal to 0.125 volts.
