Question

Question 9 (1 point) A piece of wood, cut from a magnolia tree, with density Pwood = 572 kg/m, is tied with a string to the bottom of a water-filled flask, as shown in the figure. The wood is completely immersed. The tension in the string is 0.123 N. What is the volume of the piece of wood?

Answer 1

3 quention-9 Given, density of wood, Pwood = 572 kg/m² we know density of water, o 1000 kg/m3 weight of wood, a vpg V= volume of wood g so, - acceleration due to gravity = 9.8 m/s? Buoyancy fora, vrg net force = force due to tension of string vog-upg T [ Tension, = 0.123. To-P) g = T 2) V 0.12 3 (1000 - 572 x 9.8 2.93 x 10-5 3 V - m -5 Therefore the volume, v of the piece of wood i 2.93 X 100 4th option is the correct answer m3 th
