Why must a hypothesis be both testable and falsifiable? A Scientific Hypothesis Must Be Falsifiable A hypothesis may be testable, but even that isn’t enough for it to be a scientific hypothesis. In addition, it must be possible to show that the hypothesis is false if it really is false. Consider this statement: “There are […]
What are the main features of Rockwell hardness test?
What are the main features of Rockwell hardness test? The Rockwell hardness test is based on the measurement of the depth to which an indenter is forced by a heavy (major) load beyond the depth resulting from a previously applied preliminary (minor) load. What is the principle of Rockwell hardness test? Rockwell is a method […]
Which house is most powerful in astrology?
Which house is most powerful in astrology? Because the angular houses are the most powerful places in the chart (Lilly says “Planets in angles do more forcibly show their effects”), succedent houses—which are less powerful than the angular but more powerful than the cadent houses—also have a quality of appertaining to the angular houses, much […]
Which two solutions have similar solubilities at 40 C?
Which two solutions have similar solubilities at 40 C? Answer is: Na₂HAsO₄ and Na₂SO₄. 1) Solubility of NaCl (sodium chloride) at 40°C is 36.3 grams. Is the largest amount of solute that can dissolve? In most cases, only a certain maximum amount of solute can be dissolved in a given amount of solvent. This maximum […]
What is the electric field inside a conducting shell?
What is the electric field inside a conducting shell? * The electric field inside the conducting shell is zero. Why do you expect the electric field inside the shell to be zero according to Gauss theorem? the electric field inside is zero because charge enclosed by spherical sphere is zero. What is the strength of […]
What are the two features of plateau?
What are the two features of plateau? A plateau is a flat, elevated landform that rises sharply above the surrounding area on at least one side. Plateaus occur on every continent and take up a third of the Earths land. They are one of the four major landforms, along with mountains, plains, and hills. What […]
What are the 10 steps of the rock cycle?
What are the 10 steps of the rock cycle? Metamorphic rocks underground melt to become magma. When a volcano erupts, magma flows out of it. (When magma is on the earth’s surface, it is called lava.)…When the particles are carried somewhere else, it is called erosion. Transportation. Deposition. Compaction & Cementation. What is the rock […]
How is Crispr done?
How is Crispr done? The CRISPR-Cas9 system works similarly in the lab. Researchers create a small piece of RNA with a short “guide” sequence that attaches (binds) to a specific target sequence of DNA in a genome. The RNA also binds to the Cas9 enzyme. Why is Crispr so useful? CRISPR is an acronym for […]
How does temperature increase reaction rate?
How does temperature increase reaction rate? An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. Why are some reaction very fast? Reactions in […]
