The level of boat in water is decided by net force on it by gravity (downward) and buoyant force (upward) by fluid. Force of buoyant only depend on volume, density of water and (g) and all these quantities are constant here. So, it remains constant but force of gravity (weight) decreases as mass is decreased W=mg Since downward force decreases and upward force remains the same, a net upward force arises due to brick thrown in water. As a result, the boat will float higher. 5. You have 3 blocks of different densities. Block A has a density PA = 1.5, block B has a density PB = 0.9, and block C has a density of pc = 0.5 cmas a. Do each of the blocks float in water? Water has a density of Pwater cm³ = 1.09 cm² b. Which block would be lowest in the water? Submerged counts as lowest if any blocks sink. C. Which block would sit highest in the water? d. Where would a block with a density of p = 1.0 sit in the water? cm²

To what height should a cylindrical vessel be filled with a homogenous liquid to make the force with which the liquid presses on the sides of the vessel equal to the force exerted by the liquid on the bottom of the vessel?

A 0.50 kg frog sits on a 0.20 kg ball floating in water with exactly half its volume submerged.  The volume of the beach ball is ____ m3 (note units).

A solid cone made of unknown material is suspended from a scale. Before submersion, the scale reads 100 Newtons. After submersion in water the scale reads 88.0 N as shown below. (a) What is the force of buoyancy on the cone? (b) What weight of water is displaced by the cone? (c) What mass of water is displaced by the cone (in kg)? (d) What volume of water is displaced by the cone (in cubic meters)? (e) What is the volume of the cone (in m³)? (f) What is the mass density of the cone (in kg/m³)? (Density of water, p = 1000 kg/m³) 100 N 88.0 N
