4. The mass of neutrons and electrons are about the same.
Reason :- Mass of Neutrons (1.6726 × 10^(-27) kg) ≈ Mass of Protons (1.6726219 × 10-27 kg)
Mass of Protons >>> Mass of Electrons
Hence,
Mass of Neutrons >>> Mass of Electrons.
Answer:
Both are similar concepts.
Sound is the vibration of air particles (compression and expansion) the can reach your ears. But you can have vibration being propagated in liquids and solids as well.
Some sounds are generated in structures, so the vibration of a structure is converted to sound in air — for instance, a loudspeaker.
Explanation:
The interaction between the substances and stomata is a chemical reaction, light energy strikes at the chlorophyll molecules, whose electrons gets excited to a state of higher energy, and they come back to their state of lower energy by emission of energy, which is accepted by a chain of acceptors, and energy is generated.
I think the correct answer from the choices listed above is option A. It is by the process of photosynthesis that would help counteract with human interactions. The carbon dioxide emitted by human activities can be used by this process to produce more oxygen.
Answer: The SI unit of force is the newton, symbol N.
