Oy vey (Yiddish: ××± ×°×² â) or oy vey ist mir is a Yiddish phrase expressing dismay or exasperation. Also spelled oy vay, oy veh, or oi vey, and often abbreviated to oy, the expression may be translated as, oh, woe! or woe is me!.Its Hebrew equivalent is oy vavoy.he Latin equivalent is heu, vae! (pronounced, hoi, vai, amongst others); a more standard expression would be o, me miserum, or heu, me miserum. According to Chabad.org, an alternative theory for the origin of the Yiddish expression is that oy stems from Biblical Hebrew, and that vey is its Aramaic equivalent.
Chemical Reactions Used to Generate the Gas Inside the airbag is a gas generator containing a mixture of NaN 3, KNO 3, and SiO 2. When the car undergoes a head-on collision, a series of three chemical reactions occur inside the gas generator.
Front airbags have been standard on all new cars since 1998 and light trucks since 1999. Most vehicles had them even before then. Crash sensors connected to an onboard computer detect a frontal collision and trigger the bags. The bags inflate in a few millisecondsâthe blink of an eyeâthen immediately start deflating.
