Acertain radioactive (parent) nucleus transforms to a different (daughter) nucleus by emitting an electron and a neutrino. the parent was at rest at the origin of an xy coordinate system. the electron moves away from the origin with linear momentum (-5.6 x 10-22 kg m/s) ; the neutrino moves away from the origin with linear momentum (-6.9 x 10-23 kg m/s) . what are (a) the magnitude and (b) angle (from the +x axis) of the linear momentum of the daughter nucleus? (c) if the daughter nucleus has a mass of 8.7 x 10-26 kg, what is its kinetic energy?

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s.part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.
