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.
Answer:D
Explanation:
Given
mass of object
Distance traveled
velocity acquired
conserving Energy at the moment when object start falling and when it gains 12 m/s velocity
Initial Energy
Final Energy
where is friction work if any
Since Friction is Present therefore it is a case of Open system and net external Force is zero
An open system is a system where exchange of energy and mass is allowed and Friction is acting on the object shows that system is Open .
Answer:
h = 10 m
Explanation:
given,
mass of platform = 50 Kg
Kinetic energy = 5000 J
height from which the diver dove = ?
taking acceleration due to gravity = 10 m/s²
using conservation of energy
Kinetic energy is converted into mechanical energy
K.E = P.E
K.E = m g h
5000 = 50 x 10 x h
500 h = 5000
h = 10 m
The height from which the diver dove is equal to h = 10 m
