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.
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. 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.
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
false
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. 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 AND False OR True evaluates to True. IT seems like it does not matter which is evaluated first as: (True AND False) OR True = False OR True = True True AND (False OR True) = True AND True = True But, it does matter as with False AND False OR True: (False AND False) OR True = False OR True = True False AND (False OR True) = False AND True = False and True OR False AND False: (True OR False) AND False = True AND False = False True OR (False AND False) = True OR False = True Evaluated left to right gives a different answer if the operators are reversed (as can be seen above), so AND and OR need an order of evaluation. AND can be replaced by multiply, OR by add, and BODMAS says multiply is evaluated before add; thus AND should be evaluated before OR - the C programming language follows this convention. This makes the original question: True AND False OR True = (True AND False) OR True = False OR True = True
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. 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.
