False. Gamma rays are photons (light pieces), and have zero charge.
It is false. A gamma ray has no charge, but it is an electromagnetic wave, not a particle.
True. The strength of the electric field created by a charged particle is inversely proportional to the square of the distance from the particle. As the distance decreases, the electric field strength increases.
False. The strength of an electric field weakens with distance from a charged object. The field strength is inversely proportional to the square of the distance from the object.
True. When you comb your hair, the comb becomes charged by friction due to the triboelectric effect. Since hair is also a good candidate for triboelectric charging, it becomes oppositely charged to the comb and is therefore attracted to it.
False. Electric forces are caused by the interaction of charged particles (like electrons and protons), but friction and contact forces are primarily a result of mechanical interactions between objects.
False, neutrons are not charged and gamma rays aren't charged particles.
It is false. A gamma ray has no charge, but it is an electromagnetic wave, not a particle.
true
True. A gamma ray is a high-energy photon, and thus moves at the speed of light. And, like all photons, it has no charge.
false
False. If an atom gains or loses electrons, the result is called an ion, not a molecule.
Protons are positively charged but found in the NUCLEUS (so false). Electrons are found in the orbitals (but are negatively charged)
True. When a surface loses electrons, it becomes positively charged because it has more positively charged protons compared to the negatively charged electrons.
False
True. The strength of the electric field created by a charged particle is inversely proportional to the square of the distance from the particle. As the distance decreases, the electric field strength increases.
False. The strength of an electric field weakens with distance from a charged object. The field strength is inversely proportional to the square of the distance from the object.
True. Gamma ray emission involves the release of high-energy photons from the atomic nucleus without changing the mass or nuclear charge of the emitting atom.
