A student was watching a video about throwing a baseball at a "dunking station". The baseball has to have a momentum of 4.47 kg*m/s to activate the switch to dunk
someone (the company labeled the dunking station so
labeled the dunking station so you know the momentum
needed). If a MLB baseball is being used (.149 kg), how fast does the baseball need to
be thrown?

Research the neutrino using the internet and report your findings. in a nuclear decay, the nucleus of an atom splits apart. larger particles can be detected and their masses and velocities can be recorded. explain how the existence and properties of the neutrino could be predicted using the conservation laws.

Astudent is given an assignment to demonstrate diffraction. he takes a photograph of a straw in a glass of water. the straw appears bent at the water level. which best describes this example? a) this is a good example of diffraction. b) this is an example of dispersion and not diffraction. c) this is an example of refraction and not diffraction. d) this is an example of reflection and not diffraction.

Which best represents the law of conservation of mass ?
