How does radiation directed at the Earth fail to reach the surface?
Some of it is reflected back into space. Some of it is absorbed by the atmosphere. Some of it is scattered by the atmosphere.
Outermost principal energy level?
That, or they, would be the outer most shell electrons. The one(s) that get shared when elements bond. The one that moves out and up when struck by a photon. The one that makes light when it falls back down (gives up its' energy) to its' original shell. ADD: It is a valence electron.
How is electron transport similar to electricity?
Electron transport is electricity. Electricity is the flowing of electrons along a substrate such as copper. Electrons will move from one source to another source. In household electricity the electrons travel along the path and back to the original source.
Why cant conductors generate static electricity when rubbed together?
Static electricity causes electrons to move from one material to the other. In an insulator, these electrons can't flow back to equalise the charges, whereas in a conductor they can; so whilst they could conceivably generate static electricity, it would be lost as quickly as it was made.
Why must there be two connections to a batter and to a light bulb?
The electrons must go from the battery to the light-bulb, then come back again to the battery through the other connection. If there is only one connection, there will soon (within microseconds or so) be an accumulation of electrons that will repel any additional electrons - the current will stop flowing.
What is different between secondary electron image and back scattered electron image?
Secondary electron images show morphology and topographyof a sample. The more the number of electrons reaching the detector, the brighter the image is. Back scattered electron images show difference in composition - or more exactly, difference in atomic number over a sample. The higher the atomic numbers of the atom, the more backscattered electrons are bounced back, making the image brighter for larger atoms.A second difference is back scattered electrons are produced by the elastic interaction of the beam electron with nuclei of atoms in the specimen. No energy is lost as it is elastic interaction. On the other hand secondary electrons are produced by inelastic interaction of beam electrons with electrons in the atom rather than the nucleus. Since it is inelastic interaction, there is energy loss.
What is strain back effect in shaping machine?
During shaping operation, the cutting tool exerts a force on the workpiece. This force can be resolved in two components(horizontal,vertical). Horizontal force is the cutting force. Vertical force causes the workpiece material to deform elastically. We know, an elastically deformed body regains its original shape after the force is removed. So, after the tool move past one elastically deformed section of the workpiece, the section is raised up as the force is removed from the section. This effect is called "Strain back effect".
What is thermal relaxation?
The relaxation back to thermal equilibrium of one very dilute species of charged particle in a heat bath of different neutral particles, with which they collide elastically.
What will be the result when a light body elastically collides with a massive body at rest?
When the massive body is extremely heavier, the lighter one will be bounced back. For some details you can see in momentum theorem.
When to use the word stills?
That hideaway shack back up in the hills had three operating stills scattered around it.
What percentage of the suns energy is scattered or reflected back into space what causes this loss of solar energy?
it's either 40% or 60%
What circuit property holds back the movement of electrons?
That would be resistance.
Are electricons used up in a circuit?
No, electrons are not used up in a circuit. The movement of these electrons provides usable power, but the flow of electrons (defined as current) does not terminate at some random location, it continues back to the source (ie, electrons flow in a loop from the power plant, out to your home, back to the power plant). Mechanical and chemical energy are used to start these electrons moving; this is the energy you use when you use electricity.
How does radiation directed at the Earth fail to reach the surface?
Some of it is reflected back into space. Some of it is absorbed by the atmosphere. Some of it is scattered by the atmosphere.
What is bonds that forms when electrons are transferred from one atom to another?
A electron bond is a bond that forms when electrons are transferred from one atom to another, When a electron bond forms the electrons are transferred to one atom back.
When Rutherford performed his metal foil experiment did the alpha particles pass straight through the foil or bounce back?
The alpha particles beam is scattered.
What is back bonding in metal carbonyls?
carbonyl in electron acceptor ligand it has empty orbital which can accept electron as well as filled orbital which can donate electrons . when carbonyl binds with metal it donates the electrons ,metal which is in low oxidation state now has excess electrons and it becomes stable if it back donate some electrons to the carbonyl in its anti bonding orbital forming a pi bond
