När man kammar håret med en plastkam kan det hända att det står rakt ut. Man har så kallad "Bad Hair Day". Vad beror det på?
Markera det rätta svaret.
Friktionen skapar statisk elektricitet vilket får ditt hår att stå rakt upp Du får ett överskott eller underskott av elektroner Elektronerna blir tvingade att flytta på sig vilket gör dem stela och ditt hår står rakt ut Varför dyker problem med statiskt elektricitet främst fram på vintern?

När luften är torr kan inte elektronerna flytta på sig som de vill göra, eftersom att vatten leder el, men på vintern är det fuktigt Luften innehåller mycket vatten som gör att elektronerna fritt kan röra på sig men på vintern är luften mycket torrare Bryr mig inte, kylan är ett tillräckligt stort problem ändå... När man plockar tvätten ut torktumlaren fastnar den lätt i allting. Varför?

Torktumlaren läcker lätt elektroner som fastnar på kläderna och får dem att fastna i allting De laddas upp av varandra när de gnids mot varandra och far omkring och bildar statisk elektricitet Elektroner gillar inte rörelse och vill därför bort från kläderna och skapar statiskt elektricitet Jag blir snurrig av torktumlare Varför blir glaset på en tv-skärm mer dammigt än på ett vanligt fönster

Elektronerna på tv-skärmen drar till sig damm och smuts Tv-skärmen vibrerar av alla elektroner och drar till sig smuts och damm Skärmar drar till sig smuts LÅT MIG TITTA PÅ TV!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Du och din kompis innehåller både en mängd elektroner vardera. Varför påverkar ni inte varandra med då med elektriska krafter?

Eftersom att människor har lika många elektroner som protoner är man neutral och attraherar eller repellerar inte En människa har fler protoner än elektroner vilket försvagar elektronerna och då kan de varken attrahera eller repellera Människans hud gör att elektroners kraft minskar kraftigt Varför är ett kostängsel obehagligt?

För att stängslet har ett lika kraftiga stötar som en blixt Kostängslet ger dig en kraftig stöt för att den ständigt har ett starkt underskott av elektroner Kostängslet ger dig en kraftig stöt för att den ständigt har ett starkt överskott av elektroner
