Answer:
Explanation:
From the given information, the LED is operating with a given wavelength of 850 nm or 0.85 μm.
Hence, the material dispersion is
Now, using the pulse spread formula:
Thus, the pulse spreading as a result of material dispersion is:
Answer:
Charge enter a 0.100 mm length of the axon is
Explanation:
Electric field E at a point due to a point charge is given by
where is the constant =
is the magnitude of point charge and is the distance from the point charge
Charges entering one meter of axon is
Charges entering 0.100 mm of axon is
substituting the value of in above equation, we get charge enter a 0.100 mm length of the axon is

The answer is D. Current.
1. A body is in motion when it changes its position at a certain time/duration.
2. Speed is related to how fast a body is moving.
3. Speed means that a body is moving and covering distance at a certain time.
4. Speed<span> is the distance traveled by an object where as, </span>velocity<span> is distance traveled by an object per unit time in a particular direction. </span>
5. Velocity is the rate of change of distance or direction of a body with respect to time.
