Sentences with phrase «positive electric charge»

Doing so lets macrophages transfer positive ions — and a positive electric charge.

For example, a proton has a positive electric charge, but an antiproton has a negative electric charge.

The basic idea is that, in the case of large nuclei such as gold, which have a very large positive electric charge, electromagnetic interactions play a much more important role in particle production than they do in the case when two small, equally charged protons collide.

The molecules are polar, with a positive electric charge on rubidium and a negative charge on potassium.

The gas in the accretion disk is hot enough for some of its atoms to lose electrons and become ionized — that is, to take on a positive electric charge.

Not exact matches

The scientist tells us much, though much of it is still tentative, and we read of the positive or negative electric charge carried by different particles, and the manner of their operation within the atom because of this relationship.

When an intense laser pulse strikes a plasma of electrons and positive ions, it shoves the lighter electrons forward, separating the charges and creating a secondary electric field that pulls the ions along behind the light like water in the wake of a speedboat.

An electron, for example, which has a negative electric charge, also has a twin, called a positron, with a positive charge.

Protons and electrons carry positive and negative electric charges, respectively, but no known particle has a magnetic charge.

When electric current passes through the cell, positively charged ions from the compound are attracted to the negative coil and negatively charged ions are attracted to the positive coil, splitting the material and yielding its constituent elements along with new compounds.

But adding parallel magnetic and electric fields introduces a chiral preference: The magnetic field aligns the spins of the positive and negative particles in opposite directions, and the electric field starts the oppositely charged particles moving — positive particles move with the electric field, negative ones against it.

As they go, the waves slightly displace atoms in the semiconductor, shifting positive atomic nuclei off center from their surrounding electrons and subtly altering the electric charge of the atoms.

Oxides, a ferroelectric material, develop an internal electric field because their ions move, causing positive / negative charges.

When the animal sends out an electric pulse, most of the charge comes from its head, which Catania calls the «positive pole.»

This layer resides between two electrodes that can reverse the direction of its polarization — the alignment of positive and negative charges used to represent «0» and «1» in binary computing — by applying electric voltage to it.

Such currents arise from each object's fluctuating electric dipoles, or, its distribution of negative and positive charges.

When the chip's electrodes apply an oscillating electric field, the positive and negative charges inside the nanoparticles reorient themselves at a different speed than the charges in the surrounding plasma.

Electrodes are placed above and below the capsule film: when a positive or negative electric field is applied to an individual electrode, the color particles with the corresponding charge move either to the top or the bottom of a capsule, coloring the display in that spot and outlining an image or text.

When the wind blows through them, it separates positive and negative charges as it moves the mist, which builds up to an almost 200,000 volt direct electric current that the system transmits through a high voltage cable back to the electrical grid on land.

I'm tending to believe that the aha explanation of the mystery lies in the fact that the negative electric charge is associated with a light particle of mass about 511 keV; while the positive charge is associated with the proton mass of about 938 MeV, a ratio of about 1836.
