Why is ecological footprint bad?
Why is ecological footprint bad? The ecological footprint is a measure of the resources necessary to produce the goods that an individual or population consumes. Finally, the lack of correlation between land degradation and the ecological footprint obscures the effects of a larger sustainability problem. What causes a high ecological footprint? Resource consumption such as […]
How do you kill a kangaroo rat?
How do you kill a kangaroo rat? Trapping with snap traps is probably the most efficient and humane method for kangaroo rats. Mouse traps will suffice for smaller animals, but Victor® “museum specials” or rat traps are needed for larger kangaroo rats, particularly the bannertail. Why do kangaroo rats not drink water? Because their habitats […]
What makes a good learning space?
What makes a good learning space? Muted colours, gentle lighting, comfortable seating and, when needed, screens for privacy must all be taken into account as well as making sure they are still flexible enough for the individual needs of every pupil. How does space affect learning? With responses from over 1600 educators, our study reveals […]
What is the angle of incident ray?
What is the angle of incident ray? In geometric optics, the angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal. The angle of incidence at which light is first totally internally reflected is known as the […]
What is difference between IR and UV?
What is difference between IR and UV? IR and UV radiation are a small part of the electromagnetic spectrum. The visible light has a wavelength of 380 nm to 760 nm. The area alongside with a longer wavelength is the IR spectrum. The area next to the visible light, with a shorter wavelength, is the […]
Why do bubbles form in boiling water?
Why do bubbles form in boiling water? Boiling begins near the source of heat. When the pan bottom becomes hot enough, H2O molecules begin to break their bonds to their fellow molecules, turning from sloshy liquid to wispy gas. The result: hot pockets of water vapor, the long-awaited, boiling-up bubbles. Why does lower air pressure […]
What are the 3 magnetic materials?
What are the 3 magnetic materials? Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone. Does the human […]
What is the electromagnetic spectrum used for?
What is the electromagnetic spectrum used for? Nearly all frequencies and wavelengths of electromagnetic radiation can be used for spectroscopy. Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Which color is the most refracted? violet light What is required for refraction? For refraction to occur […]
