Blood flow doesn't change direction. They always head for the same direction.
We have suppose the current flow in opposite to the direction of flow of electron.AnswerA.C. current reverses direction every half-cycle.
Positive electrical flow is electrons flowing in one direction in a wire, if they change the direction of flow that would be a negative flow. If they change direction quickly, say 60 times a second, that would be alternating current, which is what we have in the united states as household electricity.

a transverse wave is a moving wave that consists of oscillations occurring perpendicular (or right angled)to the direction of energy transfer.

This is because fluid pressure always acts in a direction such that the solid in it(whether submerged or not) goes out of the fliud.If the fliud is accelerating horizontally the fluid would want no disruption in its flow and hence take the solid in it in a perpendicular direction(ie the direction of the acceleration).
Longitudinal Wave:The oscillation is is parallel to the direction of wave travel.Example:sound, spring,"P_type" earthquake waveTransverse Waves:The Oscillation is perpendicular to the direction of wave travel.Example:radio or light waves , string, "S-type", earthquake waves.

Movement in a transverse wave is perpendicular to the source. Therefore, individual particles move up & down.
in which direction does the river Shannon flow?
When the planet's axis is tilted, it means that during orbit, for the hemisphere whose axis is tilted towards the sun, its surface will be more perpendicular with regard the direction of travel of light from the sun to the planet. Conversely, if the axis is tilted away from the sun, its surface will be less perpendicular. The solar energy obtained by a surface is directly proportional to the flux of photons and the flux is dependend on the angle between the surface and the direction of photon travel by the relationship f = f0sin(θ) where f is flux, f0 is the maximum flux, and θ is the angle between the surface and the direction of travel. We can see that if θ is 0 degrees (i.e. surface parallel to flow), the flux is zero, and if θ is 90 degrees (i.e. surface perpendicular to flow), the flux is the maximum flux. Therefore, the closer a surface is to perpendicularity with the direction of flow, the greater flux it gets. Therefore, the hemisphere whose part of the axis tilts toward the sun will be more perpendicular to the direction of flow and receive more solar energy while the other hemisphere receives less.
Electro-magnetic waves are comprised of an H field (Magnetic-field) and E field (Electric-field) at perpendicular angles to each other. The E field is generated in the axis of the current flow. The H field is generated perpendicular to the axis of the current flow. Which way up the Fields are or alternatively which direction they rotation defines the polarization.
