Answer: Electric current
Explanation: The direction of the magnetic field produced by an electric current will change when the direction of the electric current changes.
To solve this problem we can use the concepts related to the change of flow of a fluid within a tube, which is without a rubuleous movement and therefore has a laminar fluid.
It is sometimes called Poiseuille’s law for laminar flow, or simply Poiseuille’s law.
The mathematical equation that expresses this concept is
Where
P = Pressure at each point
r = Radius
Viscosity
l = Length
Of all these variables we have so much that the change in pressure and viscosity remains constant so the ratio between the two flows would be
From the problem two terms are given
Replacing we have to
Therefore the ratio of the flow rate through capillary tubes A and B is 1/32
Answer:
35m
Explanation:
25m + 10m = 35m east.
*(adding since it's in the same direction)
