How do objects become electrically charged? a magnet rubbed on a rope electrically charges the object. a, protons are rubbed from one object to another. b. electrons are transferred from one object to another. c. charged atoms are rubbed from one object to another.

Option B

Explanation: Electrons, protons and neutrons basically make an atom.

Neutron has no charge - electrically neutral

Protron carries a positive charge

Electron carries a negative charge.

The gain or loss of electrons determines whether an object becomes positively or negatively charged. If there is gain in electron, object becomes negatively charged; if otherwise, it becomes positively charged.

So, it is a function of electron transfer.

The answer is option B

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
