a sound wave traveling through dry air has a frequency of 16hz a wavelength of 22 m and a speed of 350 m/s. when the sound wave passes through a cloud of methane its wavelength changes to 28 m while its frequency remains the same what is its new speedA. 448 m/sB. 9,800 m/sC. 13 m/sD. 350 m/sSUBMIT

Acyclotron is used to produce a beam of high-energy deuterons that then collide with a target to produce radioactive isotopes for a medical procedure. deuterons are nuclei of deuterium, an isotope of hydrogen, consisting of one neutron and one proton, with total mass 3.34×10−27kg. the deuterons exit the cyclotron with a kinetic energy of 6.40 mev .a-what is the speed of the deuterons when they exit? b-if the magnetic field inside the cyclotron is 1.25 t, what is the diameter of the deuterons' largest orbit, just before they exit? c-if the beam current is 350 μa how many deuterons strike the target each second?
