and I don't know much about them. I know there are different ratings, layers, etc. Also, what about flame retardant undergarmets. (This is for stock car racing). Can anyone with experience with this give me any advice? His old suit is worn out and I want to surprise him with a new one. Thanks!
Ouch! A lot, I am pretty optimistic. Put some cold water on your finger, then some margarine.Band aid. It will feel a lot better.
basically the 'relax' mass of a photon is massless. it has a mass while it somewhat is on the pass and for this reason laid low with gravity. How a lot mass a photon has is set by utilizing the capability of the photon (xrays and gamma very extreme, infrared low) on condition that Emc^2, and c is continuous for all photons E is proportional to the mass. greater oftentimes, if capability/stress is utilized on an merchandise, it starts off shifting as consistent with Newtonian regulations because of the fact the capability is punctiliously used as much as enhance up the object. in spite of the fact that Einstein postulated that no longer all of the capability is used up in accelerating the object; a element of it is going into increasing its mass. (now there are 2 hundreds one something mass while the physique is at relax and what's further to it while it strikes). This actually ability, bigger the rush you supply heavier the object will become, and to push a physique to acquire velocity of sunshine demands countless capability (for this reason velocity of sunshine is a strict bigger sure)
