What is a chemical property simple definition? A chemical property is any of a material’s properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance’s chemical identity. They can also be useful to identify an unknown substance or to separate or purify […]
What element is not found in nature?
What element is not found in nature? Technetium. The first element that was synthesised, rather than being discovered in nature, was technetium in 1937. This discovery filled a gap in the periodic table, and the fact that no stable isotopes of technetium exist explains its natural absence on Earth (and the gap). What is a […]
How do I run for the first time?
How do you know what the dependent variable is?
How do you know what the dependent variable is? The variables in a study of a cause-and-effect relationship are called the independent and dependent variables. The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent […]
What are two ways to calculate gravitational potential energy?
What are two ways to calculate gravitational potential energy? Gravitational potential energy changes into kinetic energy. The equation for gravitational potential energy is GPE = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 on Earth), and h is the height above the ground in meters. How do […]
Why do the dark-colored mice living on lava flows have white underbellies?
Why do the dark-colored mice living on lava flows have white underbellies? The mice’s underbellies are white because there’s so selective pressure for it to be dark; the predators come from above. The differences in mouse fur color are driven by natural selection. Why do the pocket mice in the dark lava environment have white […]
What is an example of deductive reasoning?
What is an example of deductive reasoning? For example, “All men are mortal. Harold is a man. Therefore, Harold is mortal.” For deductive reasoning to be sound, the hypothesis must be correct. It is assumed that the premises, “All men are mortal” and “Harold is a man” are true. What is induction method of teaching? […]
What is one oscillation of a simple pendulum?
What is one oscillation of a simple pendulum? One oscillation of a simple pendulum is one complete cycle of swinging one way and then returning to its original starting position. How do you find the frequency of oscillation of a pendulum? How to analyze a pendulum in swing Determine the length of the pendulum. Decide […]
What would have resulted from the functions of prokaryotes on early Earth?
What would have resulted from the functions of prokaryotes on early Earth? The most appropriate answer would be option D. The first life appeared on earth was probably the prokaryotes. Some of them called cyanobacteria discovered the process of harnessing energy from the sun, that is, photosynthesis. The oxygen was released as the byproduct of […]
Is Fusion a chain reaction?
Is Fusion a chain reaction? Can fusion cause a nuclear accident? No, because fusion energy production is not based on a chain reaction, as is fission. What is chain reaction with example? In chain reaction. Nuclear chain reactions are series of nuclear fissions (splitting of atomic nuclei), each initiated by a neutron produced in a […]
