Why can a machine never have an efficiency of 100 %? A machine cannot be 100 percent efficient because output of a machine is always less than input. A certain amount of work done on a machine is lost to overcome friction and to lift some moving parts of the machine. Is there a 100 […]
What is the formula for frequency of light?
What is the formula for frequency of light? Divide the speed of light, ~300,000,000 m/s, by the wavelength in m. This gives you the wave’s frequency. What is the frequency of red light? around 430 terahertz Does blue or red light have a higher frequency? Blue light has shorter waves, with wavelengths between about 450 […]
Is energy transferred when two atoms collide?
Is energy transferred when two atoms collide? These atoms frequently collide and transfer energy between one another. Therefore, when two atoms collide and start to oscillate, some energy may be transferred to other particles by collisions. If this happens, a stable interaction can form between the two particles; they will “stick” together. At what point […]
What kind of process is radioactive decay according to the clip?
What kind of process is radioactive decay according to the clip? Answer. Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. What happens to a radioisotope when it undergoes nuclear […]
What is the temperature difference between steam and boiling water?
What is the difference between being charged and being indicted?
What is the difference between being charged and being indicted? A charge is brought against someone by a prosecutor. But in an indictment, a grand jury brings the charges against the defendant. All indictments are charges, but not all charges are indictments. How do you know if you’re being indicted? Basically, if federal agents came […]
What is the force of gravity in Newtons?
What is the force of gravity in Newtons? G represents the gravitational constant, which has a value of 6.674⋅10−11N(m/kg)2 6.674 ⋅ 10 − 11 N (m/kg) 2 . Because of the magnitude of G , gravitational force is very small unless large masses are involved. Is gravity a pushing force? In general relativity, gravity neither […]
What is the unit for magnitude?
What is the unit for magnitude? Especial names and symbols magnitude symbol unit frequency n,f hertz force F newton pressure p pascal energy E joule How do you explain magnitude? English Language Learners Definition of magnitude : the size, extent, or importance of something. : a number that shows the brightness of a star. : […]
What is a good soil index?
What is a good soil index? The index ranges are as follows: 0–10 is very low; 11–25 is low; 26–50 is medium; 51–100 is high; and 100+ indicates very high levels of these nutrients. When levels are low, plants will respond to addition of these nutrients. What are the factors affecting organic matter levels in […]
Which is healthier cocoa or cacao?
Which is healthier cocoa or cacao? Cacao is higher in protein, fibre, magnesium and iron. Cocoa powder without added sugar is still high in nutrition and is a more affordable option. Gram per gram cacao is more nutritious. However when you factor in that cocoa is far cheaper it means that per dollar cocoa is […]
