How many electrons pass through a lamp in 1 minute if the current is 200? A current of 200 mA is flowing through the lamp. One ampere is the current that flows through the lamp when one coulomb of charge passes in one second. The charge of an electron is 1.602*10^-19 C. How many electrons […]
Why would someone want to process their film in the darkroom?
Why would someone want to process their film in the darkroom? Today’s photographic film is made of plastic coated by an emulsion with light sensitive materials. Why would someone want to process their film in the darkroom? It gives the photographer greater control over the print. Chemical temperature is important while developing film, but not […]
What is an example of energy and matter?
How do you know if something is acidic or basic?
How do you know if something is acidic or basic? To determine whether a substance is an acid or a base, count the hydrogens on each substance before and after the reaction. If the number of hydrogens has decreased that substance is the acid (donates hydrogen ions). If the number of hydrogens has increased that […]
What is the difference between permeability and susceptibility?
What is the difference between permeability and susceptibility? Permeability is the measure of the resistance of a material against the formation of a magnetic field. A closely related property of materials is magnetic susceptibility, which is a dimensionless proportionality factor that indicates the degree of magnetization of a material in response to an applied magnetic […]
Why do some trees not lose their leaves?
Why do some trees not lose their leaves? Evergreen trees don’t have to drop their leaves. They have very strong leaves rolled up tight, like long, thin needles. This shape allows the evergreens to conserve water, which is needed for photosynthesis. Because they have more water than their deciduous cousins, their leaves stay green, and […]
How did Darwinism affect society?
How did Darwinism affect society? Darwinism allowed us to gain a better understanding of our world, which in turn allowed us to change the way that we think. By being able to apply this to other animals, it changed the way that people thought about life on earth and opened new doors for science in […]
What was the Alvarez theory?
What was the Alvarez theory? theory formulated by American scientists Walter and Luis Alvarez. This theory states that the impact of an asteroid on Earth may have triggered the extinction event by ejecting a huge quantity of rock debris into the atmosphere, enshrouding Earth in darkness for several months or longer. What is the evidence […]
What will be the slope of a graph of T 2t 2 versus L?
Which two pieces of fossil evidence support the idea of continental drift Brainly?
Which two pieces of fossil evidence support the idea of continental drift Brainly? The following fossil evidence supports the idea of continental drift: -Glossopteris : fossils of the seed fern Glossopteris are found across all of the southern continents. But the plants’ seeds were too heavy to be carried across the ocean by wind. –Lystrosaurus: […]
