Answer:
The resistance of the axon is .
Explanation:
Given that,
Inner diameter of the model of an axon,
Radius of the model,
Resistivity of the fluid inside the tube wall,
Length of the axon, l = 2 mm = 0.002 m
We know that the resistance in terms of resistivity of an object is given by :
So, the resistance of the axon is . Hence, this is the required solution.
Explanation:
(a) A circuit has 50 Ω, a 100Ω and a 150 Ω resistor are connected in series. We know that in series combination, current through each resistor is same. So, current through a 50 Ω, a 100Ω and a 150 Ω resistor is same.
(b) Ohm's law of given by :
V = I R
V is potential difference. As I is same, so, the resistor having highest resistance will have highest potential difference. So,
.
Hence, this is the required solution.
The force of gravity increases with mass, but decreases with increasing distance between objects.
