Why do chips gain mass in salt solution? When the chips were put in distilled water they gain mass because the chips gain water from the surrounding solution due to osmosis. The process of osmosis causes a net flow of water across the semi permeable membrane, from a solution with a high water concentration to […]
Do we age in space?
Do we age in space? We all measure our experience in space-time differently. That’s because space-time isn’t flat — it’s curved, and it can be warped by matter and energy. And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s because […]
What is the importance of diffraction?
What is the importance of diffraction? Diffraction is a natural phenomenon and an important tool that helps scientists unravel the atomic structure of our world. How is a CD an example of diffraction? As the CD spins, the laser light illuminates various pits and lands simultaneously. When we bounce light off of the CD bottom, […]
What is the similarities and differences of independent and dependent?
What is the similarities and differences of independent and dependent? The independent and dependent variables are the two key variables in a science experiment. The independent variable is the one the experimenter controls. The dependent variable is the variable that changes in response to the independent variable. The two variables may be related by cause […]
Is Gold safer than cash?
Is Gold safer than cash? Gold could be far more efficient than cash at storing wealth. Interest rates remain low, meaning that your money in the bank “earns virtually nothing,” reports CNN Money. When you account for inflation, that cash may have actually lost value. Gold is recognized as a having a long-term record of […]
What size is a photon?
What size is a photon? In this way you could say the “size” of photon is basically the width of its wavelength. The wavelength of green light is about 500 nanometers, or two thousandths of a millimeter. The typical wavelength of a microwave oven is about 12 centimeters, which is larger than a baseball. How […]
What is the advantage of main switch?
What is the advantage of main switch? The major advantage of using a main switch is that it can break the connection of both, the live and the neutral wire at the same time. This protects electrical appliances from accidental damage due to electrical faults. Why do live wires connect to switches? The switch must […]
What are the two rules of refraction?
Is it a phrase or a clause?
What are the organelles of cell?
What are the organelles of cell? An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins. […]
