so is this what i should do: W=mg m= W/g m = 36.6/9.8 m = 3.73 kg then put this in p= m/v 1000 = m/v v = m/1000 v = 3.73/1000 v= 0.00373 meter cubed then mass density of metal is p = m/v p = 3.73/0.00373 p = 1001.25 kg/mcubed how should i find the density of unknown...

help with buoyancy question thanks! An object denser than water rests on the bot- tom of a container full of water. The object has volume V and a density p = 4 pw, where pw is the density of water. What supporting force N does the con- tainer bottom exert on the object, in terms of pw...

help with oscillation problem! thanks i have no idea how to do this. could someone please explain how to do this. thank you, really appreciate it A mass of 311 g connected to a light spring of force constant 37.2 N/m oscillates on a horizontal, frictionless track. The amplitude of the...
