Human skin is most sensitive to ultraviolet light : Human skin is most sensitive to ultraviolet light of approximate wavelength 300 nm, I know the energy of the light is 6.626e-19 J. The threshold for sunburn occurs when 1 cm2 of skin absorbs about 1015 of these UV photons over an interval of seve..

Angular speed of the stone at the moment of release : One type of slingshot can be made from a length of rope and a leather pocket for holding the stone. The stone can be thrown by whirling it rapidly in a horizontal circle and releasing it at the right moment. Such a slingshot is used to throw a sto..
