Soenario 2: Blocks with the same volume, in water change to oil for 5. and 6.) 4.) When the wooden block is placed in the water and allowed to float to the top, what percentage of it is submerged? Include a diagram below with values] 5.) With the wooden block in the displacement pool, change the fluid being displaced to oil, and note the difference in the volume being displaced. Given this difference, find the percentage of the block being submerged. 6.) When changing the density of the fluid with the dense block, the volume displaced doesn't change, since it's fully submerged. What changes instea as a result? Use equations to support your answer.

Answer 1

. (4) It is given that the forces - Boyant force and force due to gravity are balanced and equal to uana de = weight blouse Foz Fg = 49N Iwater & Usubmerged ag= Istock XV block tg (this is the volume of submerged FB part water displaced - - Sblock Sweater = Usubmerged Vblock submerged & Shock - Sweter block - % Submerged = Visubmerged x 100 = Sblock x100 Vblock - swater Sweater submerged مسلسل When it was water, vom displaced or volume - = Sblock Ablocks I Now it is cil and still fa= Fg = 4qN so similarly, we get submerged stock Vstock fort V submerged = block block Scril clifference in vam being clisplaced a submerged Vsakrallyed le Loveckan.

Now the density of theid is equal to denty og block so it will be fully submerged & there will . be no displaced Volume further ie, F = fg - Sphed & work xf = 3 years * Valok / As a result - In this condition the full immersed block will neither sink nor will go up but will be suspended in the thuid 2 The volume raised in the tank will be equal to the volm of the block the height of thind raised can be find out h = Volung block botam area of tank as
