Are LED continuous or discrete? LED lights, or “Light Emitting Diodes,” as they are better known, emit a continuous spectrum. The spectrum they cover is not as broad as other colored lights or incandescent lights. How do you know if a variable is discrete? A discrete variable is a variable whose value is obtained by […]

What happens when a volume of fluid is warmed at the bottom? First, the liquid on the bottom of the pot closest to the heat source starts to get hot; as it does, it rises. The rising hot water is replaced by the cooler, more dense water molecules. The bubbles rise, due to buoyancy, and […]

What are the disadvantages of GMO Brainly? Answer: It can be dangerous to other insects that are important to our ecosystem. It sparks concerns on changing the field of agriculture. It can damage the environment. It causes unwanted residual effects. It can create more weeds. It threatens crop diversity. It has trade issues. Less Biodiversity. […]

How do you calculate percent Half Life? As you can see from this table, the amount of reactant left after n half-lives of a first-order reaction is (1/2)n times the initial concentration….Half-Lives and Radioactive Decay Kinetics. Number of Half-Lives Percentage of Reactant Remaining 1 100%2=50% 12(100%)=50% 2 50%2=25% 12(12)(100%)=25% 3 25%2=12.5% 12(12)(12)(100%)=12.5% n 100%2n (12)n(100%)=(12)n% […]

What is the main building block of life? Carbon is the universal building block for life as we know it. Its ability to form complex, stable molecules with itself and other elements, particularly hydrogen, oxygen, and nitrogen is unique. Organic chemistry involves mil- lions of compounds. What is the function of protein? Proteins are large, […]

What is the formula of circuit? The total resistance in a series circuit is equal to the sum of the individual resistances: RTotal = R1 + R2 + . . . R. Total voltage in a series circuit is equal to the sum of the individual voltage drops ETotal = E1 + E2 + . […]

Who owns water in the USA? Water corporations have identified United States public systems as potentially profitable. These are United Water, a subsidiary of the French company Suez Environment, American Water, and Siemens from Germany which acquired US Filter Corps from French Veolia Environment and runs it under the Siemens name. Who owns water in […]

Which of these is a consequence of speeding less wear on brakes? When a car is speeding, the ability of the car to make sharp bends is decreased because the time required to negotiate the bend is reduced. When at high speed, the brakes can easily fail due to high wear and tear on the […]

Why do electrons move in magnetic field? Cyclonic movements Free-electron Landau states are a form of quantized state adopted by electrons moving through a magnetic field. All charged particles interact with electromagnetic fields via the Lorentz force. This interaction causes electrons in a magnetic field to move in a corkscrew pattern. Are electrons attracted to […]

What are the similarities and differences between prokaryotic and eukaryotic cells? Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow […]
