How long does water vapor stay in the atmosphere? A drop of water may spend over 3,000 years in the ocean before evaporating into the air, while a drop of water spends an average of just nine days in the atmosphere before falling back to Earth. What is the greatest contributor to nitrous oxide in […]

What makes city lights twinkle?
What makes city lights twinkle? The exact same reason why stars appear to twinkle: atmospheric turbulence. The photons (light) from distant, pointlike sources travel through Earth’s atmosphere to reach your eye. The time-varying nature of the air in our atmosphere produces time-varying scatter, corresponding to time-varying brightness. Why do street lights blink at night? The […]
What is the impact of digitalization?
What is the impact of digitalization? Digitization has a proven impact on reducing unemployment, improving quality of life, and boosting citizens’ access to public services. What are the benefits of digitalization? Benefits of digitisation Access. The information in documents can be published in a number of ways and made available to global audiences, so that […]
What can you see with a compound light microscope?
What can you see with a compound light microscope? Compound microscopes are used to view small samples that can not be identified with the naked eye. These samples are typically placed on a slide under the microscope. When using a stereo microscope, there is more room under the microscope for larger samples such as rocks […]
Why bismuth has high boiling point?
Why bismuth has high boiling point? The boiling point of bismuth is lower than antimony because it tend to form three covalent bonds instead of five due to inert pair effect. Consequently, the attraction between the atoms of bismuth is weak, leading to lowered boiling point. Why antimony has highest boiling point? The elements included […]
What is the full electron configuration for nitrogen N )?
What is the full electron configuration for nitrogen N )? [He] 2s2 2p3 What is the correct electron configuration for an atom with 7 electrons? The correct electron configuration for a ground-state atom with 7 electrons is 1s^2 2s^2 2p^3. What is the electron configuration of an isolated H atom? Hydrogen only has one electron […]
Does work depend on displacement?
Does work depend on displacement? A conservative force is one where the work done by the force depends not on the distance the agent exerting the force traveled, but by its net displacement. The most obvious example of this is gravity. No matter how up and down your path is, the work done by gravity […]
