What are the 2 types of spectrum?
What are the 2 types of spectrum? When electromagnetic radiation is passed through a prism or grating it is split up and forms a collection of lines representing different wavelengths. This is called spectrum. The spectra can be divided into two types viz., emission and absorption spectra. What are the three types of spectrum? There […]
How can you increase the amount of work when you lift a book?
How can you increase the amount of work when you lift a book? When you lift the book, you are doing positive work, because the force you exert on it is in the same direction as its displacement. Gravity is doing negative work. As you lift the book you are increasing the object’s gravitational potential […]
Do liquids exert pressure explain?
Do liquids exert pressure explain? All the liquids exert pressure on the base or bottom and walls of their container. All the liquid have weight. When we pour liquid into a vessel, then the weight of liquid pushes down on the base of the vessel producing a pressure. The liquid exerts pressure on the base […]
What is covalent bond theory?
What is covalent bond theory? Valence Bond theory describes covalent bond formation as well as the electronic structure of molecules. The theory assumes that electrons occupy atomic orbitals of individual atoms within a molecule, and that the electrons of one atom are attracted to the nucleus of another atom. Which of the following is an […]

Why do we replicate studies?
Why do we replicate studies? When studies are replicated and achieve the same or similar results as the original study, it gives greater validity to the findings. If a researcher can replicate a study’s results, it means that it is more likely that those results can be generalized to the larger population. In what ways […]
Does solar energy have a future?
Does solar energy have a future? In 2018, solar generated about 1.5% of US electricity. Of all renewable energy generation, solar PV is expected to grow the fastest from now to 2050. Some solar-heavy grids, such as the California Independent System Operator have experienced times where over half of demand was met by solar PV. […]
