How do gamma rays work? Gamma-rays have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum. These waves are generated by radioactive atoms and in nuclear explosions. Gamma-rays can kill living cells, a fact which medicine uses to its advantage, using gamma-rays to kill cancerous cells. Why are gamma […]

How can skin drag friction be reduced? Friction drag can be reduced by delaying the point at which laminar flow becomes turbulent. This can be accomplished by smoothing the exposed surfaces of the aeroplane by using flush rivets on the leading edges and through painting, cleaning, waxing, polishing or the application of surface coatings.
