How far can you transmit electricity? about 300 miles Can you move air with electricity? Ionic air propulsion is a technique for creating a flow of air through electrical energy, without any moving parts. Because of this it is sometimes described as a “solid-state” drive. It is based on the principle of electrohydrodynamics. Is electricity […]
Is 7 other recyclable?
Is 7 other recyclable? Number 7 – OTHER: They are made of any combination of 1-6 or another, less commonly used plastic. Biodegradable plastics, like cups made of corn, are NOT recyclable. Though they have the recycling #7, this only means “other plastics”, including non-petroleum based. What number Cannot be recycled? According to environmental research […]

What is the most important function of stratospheric ozone?
What is the most important function of stratospheric ozone? Stratospheric ozone is a naturally-occurring gas that filters the sun’s ultraviolet (UV) radiation. This is typically regarded as ‘good’ ozone since it reduces the harmful effects of ultraviolet (UV-B) radiation. A diminished ozone layer allows more radiation to reach the Earth’s surface. Why is o3 unstable? […]
What is the importance of physical science in our daily life?
What is the importance of physical science in our daily life? It includes chemistry, which focuses on matter, and physics, which focuses on energy. Physical science explains everyday observations and actions. Its advances make modern life possible. What is matter made of? Matter is the “stuff” that makes up the universe — everything that takes […]
What are the 4 solstices?
What are the 4 solstices? So, in the Northern Hemisphere you have: Vernal equinox(about March 21): day and night of equal length, marking the start of spring. Summer solstice (June 20 or 21): longest day of the year, marking the start of summer. Autumnal equinox(about September 23): day and night of equal length, marking the […]
What is the difference between interference and superposition?
What is the difference between interference and superposition? Superposition is basically the addition of different waves. Interference typically refers to a condition in which the superposed waves either largely cancel (destructive interference) or largely reinforce (constructive interference). This means that they are the same, or nearly the same, frequency. What is the main difference between […]
What does healthy plasma look like?
What does healthy plasma look like? Blood plasma is the yellow liquid component of blood, in which the blood cells in whole blood are normally suspended. The color of the plasma varies considerably from one sample to another from barely yellow to dark yellow and sometimes with a brown, orange or green tinge [Figure 1a] […]
What electron microscopes are used for?
What electron microscopes are used for? Electron microscopy (EM) is a technique for obtaining high resolution images of biological and non-biological specimens. It is used in biomedical research to investigate the detailed structure of tissues, cells, organelles and macromolecular complexes. How do electron microscopes help us? The development of the electron microscopes therefore helped scientists […]
What are 4 energy concerns?
What are 4 energy concerns? In this section we examine some problems associated with the use of fossil fuels, fuel wood, uranium, hydro power plants and wind energy….Global warming Rise in mean (average) global temperature. Rising sea levels. Occurrence of weather extremes. Shifting of vegetative zones. What is the world’s energy problem? The energy problem […]
