Different types of cord sets may be used for connections to the main supply circuit. Use only a main line cord that complies with all applicable product safety requirements of the country of use.

www.bse.polyu.edu.hkElectric fields of up to 500kV/m can occur before a lightning strike, over an area of up to 100m from the eventual strike point. These can induce damaging currents into conductors and devicesconductors and devices. ... lightning strikes.
Introduction to Light and Color
www.nasa.govelectric bulb, or a match, but most of what hits the eye is reflected light. When light strikes some materials, it is bounced off or reflected. If the material is not opaque, the light goes through it at a slower speed, and it is bent or refracted. Some light is absorbed into the material and changed into other forms of energy, usually heat energy.

A cloud to ground lightning strike begins as an invisible channel of electrically charged air moving from the cloud toward the ground.

www1.eere.energy.govOnly a small portion of the energy radiated by the sun into space strikes the earth, one part in two billion. Yet this amount of energy is enormous. Every day enough energy strikes the United States to supply the nation's energy needs for one and a half years. About 15 percent of the radiant energy that reaches the earth is reflected back into ...
Time-of-Flight Mass Spectrometry
www.agilent.comapplied to the back plate of the ion pulser and ends when the ion strikes the detec-tor. The flight time (t) is determined by the energy (E) to which an ion is acceler-ated, the distance (d) it has to travel, and its mass (strictly speaking its mass-to-charge ratio). There are two well know formulae that apply to time-of-flight analysis.
