quesuon 14 :1 paint; A piece of cork, mass (7.7x10A1l g. and density (5.90:10"2) kgfmsI , is completely immersed In water of density (1.050x10\"3}kgfm3. Calculate the magnitude of the net force on the cork in Newtons to 2 sf. Noise: Your answer is assumed to be reduced to the highest power possible. HUES'EIOI'I 1:) U. DOII'IU The third harmonic of a series created by a standing air wave in a tube open at both ends is i1.087x10*3] Hz. If the length of the tube is [4.20x10A1] cm, calculate the speed of sound of the air. Give your answer in mfs to 3 sf. Note: Your answer is assumed to be reduced to the highest power possible. Your
