What are the 4 cell theory? All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. The activity of an organism depends on the total activity of independent cells. Energy flow (metabolism and biochemistry) occurs within cells. What is the cell theory […]
What happens when you mix sulfur and vinegar?
What happens when you mix sulfur and vinegar? hydrogen sulphide, formula H2S. This compund forms by a chemical reaction between the vinegar (an acid) and small amounts of metal sulphides (= compounds of a metal and sulphur). It has the well-known rotten-egg odour. These metal sulphides may be present in the ashes or may be […]
What was the conclusion of the Cavendish experiment?
What was the conclusion of the Cavendish experiment? The Cavendish experiment was significant not only for measuring Earth’s density (and thus its mass) but also for proving that Newton’s law of gravitation worked on scales much smaller than those of the solar system. What is the value of G Class 9? G is the universal […]
What are two things that use sonar?
What are two things that use sonar? Sonar uses sound waves to ‘see’ in the water. NOAA scientists primarily use sonar to develop nautical charts, locate underwater hazards to navigation, search for and map objects on the seafloor such as shipwrecks, and map the seafloor itself. There are two types of sonar—active and passive. What […]
Can cause a change in motion?
Can cause a change in motion? A force is a push or pull that can cause an object to move, stop, or change speed or direction. 3. The greater the force, the greater the change in motion. Gravity (the earth’s pulling force) and friction (the force between two surfaces) are common forces that work against […]

What happens when blue light passes through yellow filter?
What happens when blue light passes through yellow filter? The yellow filter absorbs blue. Since the light has only blue and green light in it after passing through the cyan filter, the yellow filter will absorb the blue and let only green light pass through. What are yellow glasses good for? Yellow lenses provide greater […]

What are the function of centrifugation?
What are the function of centrifugation? Centrifugation is a technique used for the separation of particles from a solution according to their size, shape, density, viscosity of the medium and rotor speed. The particles are suspended in a liquid medium and placed in a centrifuge tube. What is the importance of centrifugation? Importance of centrifugation. […]
