What is the definition of electrical energy and examples? Electrical energy is caused by moving electric charges called electrons. The faster the charges move, the more electrical energy they carry. Lightning, batteries and even electric eels are examples of electrical energy in action! … What do you understand by electrical circuit diagram? A circuit diagram […]
Do airbags actually save lives?
Do airbags actually save lives? NHTSA estimates that the combination of an air bag plus a seat belt reduces the risk of death in frontal crashes by 61 percent. From 1987-2015, frontal air bags saved 44,869 lives. In 2016, air bags are estimated to have saved 2,756 people. Should airbags be on or off? You […]
What are three examples of Commensalism?
What are three examples of Commensalism? Examples of Commensalism Remora fish have a disk on their heads that makes them able to attach to larger animals, such as sharks, mantas, and whales. Nurse plants are larger plants that offer protection to seedlings from the weather and herbivores, giving them an opportunity to grow. Tree frogs […]
Why can a machine never have an efficiency of 100 %?
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 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 […]
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 […]
