The wave speed in a guitar string of length 57.5 cm is 266 m/s. you pluck the center of the string by pulling it up and letting go. pulses move in both directions and are reflected off the ends of the string. how many seconds does it take for the pulse to move to the string end and return to the center?

Blank liquids and gases exert a buoyant force on objects placed in them

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
