The buoyant force that acts on 20,000 N ship is a. somewhat less than 20,000 N b. 20,000 N c. more than 20,000 N d. dependent on wheter it is in fresh water or salt water

A barge loaded with steel bars floats in a lock by a dam (a closed pool of water like a big swimming pool). If some of the cargo is thrown overboard the level of water in the lock will A. rise, provided it is lumber that is thrown overboard B.stay the same. C. rise, provided it is iron ore that is thrown overboard . D. rise. E. drop.

2. A small ferryboat is 4.00 m wide and 5.00 m long. When a loaded truckpulls onto it, the boat sinks an additional 4.25 cm into the river. What isthe weight of the truck? (Density of water ρ = 1000 kg/m³)

PRACTICE A Buoyant Force 1. A piece of metal weighs 50.0 N in air, 36.0 N in water, and 41.0 N in an unknown liquid. Find the densities of the following: a. the metal b. the unknown liquid 2. A 2.8 kg rectangular air mattress is 2.00 m long, 0.500 m wide, and 0.100 m thick. What mass can it support in water before sinking? 3. A ferry boat is 4.0 m wide and 6.0 m long. When a truck pulls onto it, the boat sinks 4.00 cm in the water. What is the weight of the truck? 4. An empty rubber balloon has a mass of 0.0120 kg. The balloon is filled with helium at 0°C, 1 atm pressure, and a density of 0.179 kg/m. The filled balloon has a radius of 0,500 m. a. What is the magnitude of the buoyant force acting on the balloon? (Hint: See Table 1 for the density of air.) b. What is the magnitude of the net force acting on the balloon?

if you have two vectors : A=-2i+3j-k B=-i+3j-k    find : 1. -3B 2. 2A-3B 3. Direction of A 4. Direction of B

3. Seawater has a specific gravity of 10.1 x 103 kg/m3. Determine the buoyant force by acting on a spherical buoy that has a diameter of 2.0 m.

7)Suppose you have a bowling ball resting at the bottom of a tank of pure water that is 1.0 m deep and open to the atmosphere at the top.  If you add more pure water to the tank so that the water is now 2.0 m deep (and still open to the atmosphere at the top), how does the buoyant force on the bowling ball change? 8)

A0.0569-mx 0.248-mx 0.310-m block is suspended from a wire and is completely under water. What buoyant force acts on the block? Number Units
