A tuning fork produces a sound with a frecuency of 275Hz and a wavelenght in air of 1.25 m what value does this give for the speed of sound air what would be the wavelength of the wave produced by this tunning fork in water in which sound travels at 1500 m/s

Radioisotopes often emit alpha particles, beta particles, or gamma rays. the distance they travel through matter increases in order from alpha to gamma. each radioisotope has a characteristic half-life, which is the time needed for half of a sample of radioisotope to undergo nuclear decay. which quality is desirable for a radioisotope that is used for medical imaging of a specific organ? check all that apply. half-life of several years half-life of several days half-life of several seconds emission of gamma rays emission of alpha particles ability to be attached to a compound used by the body ability to pass through the body without being absorbed
