What is Cube formula? Cube of any digit, forms by multiplying the digit by itself three times. For instance, to find the 5^{3} we need to multiply 5 three times: 5 \times 5 \times 5 = 125. Note: we write down “5 cube” as 5^{3} (the little 3 means the number appears three times during […]
How does compression happen?
How does compression happen? Compression force (or compressive force) occurs when a physical force presses inward on an object, causing it to become compacted. In this process, the relative positions of atoms and molecules of the object change. Where is lossy compression used? Lossy compression is most commonly used to compress multimedia data (audio, video, […]
Can a singularity explode?
Can a singularity explode? The Quantum Bounce Rovelli and his collaborators speculate that these quantum gravity effects not only prevent the singularity from forming, but may in fact cause the black hole to explode. But this will only happen when quantum gravity dominates–i.e., when the matter is so compact that it’s almost a singularity. Can […]
What gases do power plants produce?
What gases do power plants produce? Fossil fuel, biomass, and waste burning power plants Carbon dioxide (CO2) Carbon monoxide (CO) Sulfur dioxide (SO2) Nitrogen oxides (NOx) Particulate matter (PM) Heavy metals such as mercury. What percentage of pollution comes from power plants? Power plants are currently the dominant emitters of mercury (50 percent), acid gases […]
What is metal give example?
What is metal give example? Alloys are mixtures, where at least one part of the mixture is a metal. Examples of metals are aluminium, copper, iron, tin, gold, lead, silver, titanium, uranium, and zinc. Well-known alloys include bronze and steel. How many types of metals are there? five What are the 2 types of metals? […]
What happens if you have a positive acceleration and a positive velocity?
What happens if you have a positive acceleration and a positive velocity? Positive Velocity and Positive Acceleration Observe that the object below moves in the positive direction with a changing velocity. If the object is speeding up, then its acceleration vector is directed in the same direction as its motion (in this case, a positive […]
How do you find the emission spectrum?
How do you find the emission spectrum? Kirchhoff’s Laws. Thus, emission spectra are produced by thin gases in which the atoms do not experience many collisions (because of the low density). The emission lines correspond to photons of discrete energies that are emitted when excited atomic states in the gas make transitions back to lower-lying […]
What can Punnett squares be used to determine?
What can Punnett squares be used to determine? The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. The diagram is used by biologists to determine the probability of an offspring having a particular genotype. Why is the Punnett square a good way to […]
What happens if an object has a negative acceleration?
What happens if an object has a negative acceleration? An object with negative acceleration could be speeding up, and an object with positive acceleration could be slowing down. And if the acceleration points in the opposite direction of the velocity, the object will be slowing down. What is the equation for final velocity? Final velocity […]
