What else can I help you with?
When driving a white dash between lanes are use for what?
To indicate that traffic in that lane is flowing in the same direction as you are traveling.
What determines the magnitude and polarity of the counter-emf in a dc motor?
the magnitude is decided by the amount of flux, number of conductors, speed of the motor and the type of the winding used. the polarity is decided by the direction of rotation of the motor and the direction of armature current flowing in the motor.
What is a downward flowing air current?
A current of air with its velocity directed downwards or in a direction below the horizontal. Mathematically v.n < 0 where v is the velocity vector and n is the upward normal at the surface.
What quantities are neither vectors nor scalars?
Electric Current is neither scalar nor vector , since in electric current in a wire has both magnitude and direction but there is no meaning of triangle rule there. Also, since it gives the magnitude of charge flowing per unit time, it has nothing to do with direction.
How does the blood to a heart and lung keep flowing in the same direction?
There are two ways that blood is kept flowing in the same direction. The heart is pumping it in that direction, and blood vessels contain valves which prevent blood from flowing in the wrong direction.
What is the difference between velocity and pressure on flowing fluid?
velocity is a distance travelled per sec
What is the definition of velocity of a river?
The velocity of a river is the speed at which the water in the river is flowing in a particular direction. It is typically measured in meters per second or feet per second. Velocity can vary at different points along a river depending on factors such as stream gradient, channel width, and flow volume.
What is water called when flowing in a definite direction?
Water is called a stream when flowing in a definite direction.
When charges continually shift from flowing in one direction to flowing in the reverse direction?
. . . then that would be alternating current, or simply, 'AC'.
What is the resultant velocity of a boat if it travels south across a river at 14 km per hr. It encounters a current flowing from east to west at 9 km per hour?
The resultant velocity of a boat is 17 km/hr and the direction of the boat is SW.
When charges continually shift from flowing in one direction to flowing in the reverse direction there is a what current?
Alternating current would fit this description.
Why current density is vector quantity?
Current is not scalar. Current is a vector quantity. For simplicity, in electric circuits, current is scalar because the direction is assumed to be one way or another, rather than three dimensional.
