Answer 1

density of steel = 7700 kg/m3 Volume of steel = M = 18000 m² = 2.338 m² 7700 Xa) When submerged in boater: i Be Buovaney force T = Mg-B 7 Т= M— P..3 1 = (M-Sweter V) g , Swater- 1000 kg/m3 T= (18000– lood x 2338)x9.81 M T= 153644 Na ir by when in Air :- (Than B=0) so T=Mg T= 18000 x 9.81 M T= 176580 N
