What does static pressure mean? : the force per unit area that is exerted by a fluid upon a surface at rest relative to the fluid. How is static and dynamic pressure measured? If a gas is static and not flowing, the measured pressure is the same in all directions. But if the gas is […]
Do windmills kill bats?
Do windmills kill bats? Dead bats are found beneath wind turbines all over the world. It’s estimated that tens to hundreds of thousands die at wind turbines each year in North America alone. These bats migrate and mate primarily during late summer and early autumn, which is also when the vast majority of bat fatalities […]
How do you find the refractive index of water?
How do you find the refractive index of water? The Refractive index of water is 1.3 and the refractive index of glass is 1.5. From the equation n = c/v, we know that the refractive index of a medium is inversely proportional to the velocity of light in that medium. Hence, light travels faster in […]
What are three motion examples?
What are three motion examples? What are some examples of motion energy? Wind. A ball being thrown. Someone running. A fish swimming. What is needed when describing the change in position of an object? You can describe the motion of an object by its position, speed, direction, and acceleration. An object is moving if its […]
What is the difference between reflection and reflective practice?
What is the difference between reflection and reflective practice? Reflective practice is ‘learning through and from experience towards gaining new insights of self and practice’ (Finlay, 2008). Reflection is a systematic reviewing process for all teachers which allows you to make links from one experience to the next, making sure your students make maximum progress. […]
What animals live in the scrub forest?
What animals live in the scrub forest? Life in the desert scrub biome isn’t easy, but there are still a surprising number of animals there, thanks to all the shrubs. There are small mammals like mice, voles, chipmunks, kangaroo rats, jack rabbits, prairie dogs, etc. Larger mammals can also be found in the desert scrub […]
What is SFX and VFX?
What is SFX and VFX? Special Effects (often abbreviated to SFX) refers to on-set visual effects techniques; you could also call them ‘practical effects’. VFX is an abbreviation of Video Effects. Video Effects enabled filmmakers to achieve the same effects as on-set SFX during post-production. What movie has the best special effects? Special effects in […]
Can scanning electron microscopes see DNA?
Can scanning electron microscopes see DNA? Now an electron microscope has captured the famous Watson-Crick double helix in all its glory, by imaging threads of DNA resting on a silicon bed of nails. The technique will let researchers see how proteins, RNA and other biomolecules interact with DNA. Can cilia be seen with a light […]
What do you know about a substance it you know its temperature?
What do you know about a substance it you know its temperature? In chemistry, we define the temperature of a substance as the average kinetic energy of all the atoms or molecules of that substance. Not all of the particles of a substance have the same kinetic energy. At any given time, the kinetic energy […]
Can something have more than one type of energy?
Can something have more than one type of energy? Energy comes in many different types, which can be categorised into two basic forms – kinetic and potential. Energy can never be created or destroyed, but it can be transformed from one type of energy to another. What happens if you drop the skater onto the […]
