DNA molecules are negatively charged. When places in an electric field, like in an gel during the process of electrophoresis, they all move toward the positive electrode.
Electons make part of molecules. Air molecules are constituted mainly of hydrogen and oxygen atoms, (and other elements like nitrogen) Such molecules move freely in space, but it can't move alone, protons and neutrons are part of air molecules, except in electric circuit where electrons move alone inside of conductors.
The answer is that water molecules move by a stream of moving cytoplasm, some what like how the currents move to the ocean.
molecules moves through concentration gradient .and molecules move either in the form of ions or gas in the medium
Your body needs energy to move the molecules in your kidneys.
Gas molecules move by diffusion, and water molecules move by osmosis. Edit: Osmosis refers only to water molecules (H2O) while diffusion refers to all over molecules.
Introduce two opposite charged objects one AT A TIME and if they move IN THE SAME DIRECTION, they are in a gravitational field, if they move IN DIFFERENT direction they are in an electric field.
it will occure if the charge is positive, other wise it will move to opposite direction.
positive charge
positive
Because if you place a small object with a small electric charge in the field and release it, there's a definite direction in which it will move under the influence of the field. The direction in which a positive test-charge tries to move is defined as the direction of the electric field at that point. Since it has both a magnitude and a direction, it has all the qualifications to be recognized as a vector, and to be granted all the rights and privileges attendant thereto.
the direction of current is the direction of electrons move. the dirction of electric field can be negative to positive
Direction and electric flux density. Representing an electric field (and this works with other fields also) with lines is a sophisticated and time honored tradition. The density of lines in any region of space is proportional to the strength (magnitude) of the field in that region of space. The direction of the field is along the direction of the line at each position on each of the lines. In such a graphical representation the field direction goes out from positive charge and in towards negative charge and the visualization usually has some indication of the sign of charge or direction of the field to give the information about direction of the vector field represented by the field lines.
they naturally move left because all the molecules need to reach equilibrium
Hans Orsted first discovered that when an electric current was run through a wire and put close to a compass, the needle moved toward it. Although, he had no idea what that meant. Michael Faraday, built on his work and found that when an electric current runs through a wire, a magnetic field is produced around the wire. He also found that an electric field is around a wire it produces an electric current. The direction of the current depends on which direction the field is going in. The faster you move the electric field the stronger the current.
Electric Field between positive and negative charges. If the Electric Field in which both the positive and negative charges are present is stronger than the Electric Field between the two charges we are talking about, the the negative charge will move away from the positive charge in that positive direction of the field. If not, then the negative charge will get attracted to the positive charge and stay at the position of the positive charge. It will be pulled toward the source of the electric field. (Novanet)
Current is produced when charges are accelerated by an electric field to move to a position of lower energy.
Electric field lines are continuos because they move from +ve to -ve it means they move a particular point from A to B if they move from A to B and then to A then this path way is called discontinuous
