How do you calculate half-life examples? The quantity of radioactive nuclei at any given time will decrease to half as much in one half-life. For example, if there were 100g of Cf-251 in a sample at some time, after 800 years, there would be 50g of Cf-251 remaining. After another 800 years (1600 years total), […]
What do all the physical properties of minerals result from?
What do all the physical properties of minerals result from? The physical properties of minerals are related to their chemical composition and bonding. Some characteristics, such as a mineral’s hardness, are more useful for mineral identification. Color is readily observable and certainly obvious, but it is usually less reliable than other physical properties. What are […]
What does miasma mean in Greek?
What does miasma mean in Greek? In Greek mythology, a miasma is “a contagious power that has an independent life of its own. Until purged by the sacrificial death of the wrongdoer, society would be chronically infected by catastrophe.” An example is Atreus who invited his brother Thyestes to a delicious stew containing the bodies […]
What will happen if the chloroplast stops working?
What will happen if the chloroplast stops working? because chloroplasts have chlorophyll, which absorbs energy from the sun. This energy is used for photosynthesis. it also can affect the whole process of photosynthesis the green plant will not be able to carry out the process of photosynthesis which means the plant will die. What will […]
What is the relationship between absorbance and concentration?
What is the relationship between absorbance and concentration? One factor that influences the absorbance of a sample is the concentration (c). The expectation would be that, as the concentration goes up, more radiation is absorbed and the absorbance goes up. Therefore, the absorbance is directly proportional to the concentration. How do you calculate absorbance from […]
Can electrons travel through air?
Can electrons travel through air? In order to create an electrical current, electrons must be ripped off of the air molecules so that they are free to move and form a current. Rather, air displays a complex relationship between the applied voltage and the resulting electrical current traveling through the air. Can current flow in […]
How is Biosphere dependent on all the three spheres?
How is Biosphere dependent on all the three spheres? Answer: The atmosphere is the layer of air that stretches above the lithosphere. The Earth’s water—on the surface, in the ground, and in the air—makes up the hydrosphere. Since life exists on the ground, in the air, and in the water, the biosphere overlaps all these […]
What proves light is a particle?
What proves light is a particle? Light behaves mainly like a wave but it can also be considered to consist of tiny packages of energy called photons. Then Max Planck and others were studying the photoelectric effect and they found that certain types of metal and other materials will eject electrons when light shines on […]
Why do plants and animals depends on each other?
Why do plants and animals depends on each other? Complete Answer: A. Plants and animals depend on each other because in the ecological systems present on earth, it is impossible for any species to survive alone. Similarly, plants depend on animals for reasons like dispersal of fruits and seeds, pollination, and for the carbon dioxide […]
Why past Cannot be changed?
Why past Cannot be changed? The past cannot be changed, the future is still in your power. Can God change the past? God can change the past, the present and the future. Nothing is beyond the Supreme Lord. He can change history and He can make history. In the Bhagavad Gita (BG), Lord Krishna says, […]
