Question

A.) When a solid is dissolved in a liquid, the solid takes up spaces between the liquid molecules(the volume stays basically the same). If I have 2 containers and I dissolve 50g of NaCl in one and 50g of LiCl in the other, which container would provide your aluminum block with a greater buoyancy force(assume both completely dissolve)?
B.) If you double the radius of the aluminum cylinder, how much should the buoyancy force acting on it change(assume submerged in the same fluid)? show equations or say why

Explanation / Answer

A)buyoncy force=(rho of liquid)*volume displaced*g now rho of nacl added liquid will be more as mass is more with same volume so buyoncy force of nacl liquid will be more B) buyoncy force=(rho of liquid)*volume displaced*g volume displaced=pi*r*r*h if radius is doubled volume will be 4 times therfore buyoncy force will be quadrapled.
