Do electric car chargers lock? Whilst the plug has a latch, to prevent the plug falling out of the socket, it does not have a lock. This means that anyone can unplug the car end of your charging cable. How long can I leave my car at a charging station? Plug-in hybrids require 1-4 hours […]
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 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 […]
Can a magnetic field do work on a charged particle?
Can a magnetic field do work on a charged particle? An electric field may do work on a charged particle, while a magnetic field does no work. The Lorentz force is the combination of the electric and magnetic force, which are often considered together for practical applications. Under what conditions does a magnetic field do […]
How far can you transmit electricity?
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 […]
Who can stop a moving object?
What is a rock floating in space called?
What is a rock floating in space called? While it is floating around in space, a space rock is called a meteoroid. Some meteoroids create more light when they burn up. These extra-bright meteors are called fireballs and they can even be seen during the day. Sometimes a meteoroid doesn’t completely burn up as it […]
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.
