How many variables make a good experiment? An experiment usually has three […]
Where do all elements heavier than iron come from?
Where do all elements heavier than iron come from? 3 Answers. Elements heavier than iron are produced mainly by neutron-capture inside stars, although there are other more minor contributors (cosmic ray spallation, radioactive decay). They are not only produced in stars that explode as supernovae. What are the five common elements in Stardust? In this […]

How do telescopes collect data from stars?
How do telescopes collect data from stars? Radio telescopes collect and focus radio waves from distant objects. Space telescopes orbit Earth, collecting wavelengths of light that are normally blocked by the atmosphere. Modern telescopes collect data that can be stored on a computer. Astronomers can learn a lot about a star by studying its spectrum. […]

How do spectrophotometers work?
How do spectrophotometers work? The basic function of a spectrometer is to take in light, break it into its spectral components, digitize the signal as a function of wavelength, and read it out and display it through a computer. In most spectrometers, the divergent light is then collimated by a concave mirror and directed onto […]
What is a chemical change explain with example?
What is a chemical change explain with example? The bubbles of gas that you observed form when an antacid is dropped into water is an example of change. Another clue that a chemical change has occurred is the formation of a solid. A solid that separates out of solution during a chemical change is called […]
