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 %? 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? 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? 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? 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? While water boils at 212 F, steam is at a much higher temperature as water turns to vapor. While it is possible for water to remain in a liquid form after it has reached 212 F, it becomes an unstable liquid. Can Steam be hotter […]

What is the main goal of human relations? 1 Answer. D – the main goal of human relations is to help you relate better to others. Without human relations we would not be able to consider how our actions in the world affect the other people we interact with on a daily basis. Which of […]

Do wider tires affect gas mileage? For example, larger tires decrease your fuel economy because they are heavier, while smaller tires increase fuel efficiency. Bigger tires also have a higher rolling resistance than smaller tires which means they require more resistance and effort to get them rolling. What are good tires for rain? The 10 […]

Why is 7 a lucky number in the Bible? Number 7 is considered to be the number of the spiritual perfection because it is a symbol of God’s work. Maybe you didn’t know but number 7 was the most sacred number to the Hebrews. As we have already said, this number is a symbol of […]
