A 75kg surfer is paddling out on a 10.5ft wooden longboard with density 167kg/m3 . Seawater has specific gravity of 1.03. Assuming none of the surfer is submerged at the moment, how much of the surfboards 7cm thickness is submerged? You may assume the board is perfectly flat and the surfer has reached behind the breaks where the ocean is calm.

width of board not given

Expert Solution

The concept used in this question is of floating conditions of the Archimides principle , initially i draw the figure and then calculate the weight of the surfer and the wooden longboard , and then apply floating conditions and get the value of thickness ( h) submerged in the seawater.

Note:- As the width is not given in the problem so i assume to be 1 unit .

Say the density of air is 1.23 kg/m3 and the density of helium is 0.164 kg/m3 when both are at STP. Let's model a balloon as a sphere of radius 0.12 m, with mass 2 g. 1) What is the mass of the helium that would fill a single balloon? 2) What is the buoyant force on a single balloon? 3) What is the net force on a single balloon? 4) If we attach 0.5 m of string (properties: 800...
