A solid object weighs 17.94 N in air. When it is suspended from a scale and submerged in water, the scale reads 5.22 N. scale mass water Find the density of the object. (Use 1000.0 kg/m³ for the density of water.)

QUESTION 37 A hydraulic piston assembly filled with hydraulic fluid, has 2 pistons, 1 with an area of 1 m2, and the second piston with an area of 10 m2. If a force of 10 Newtons pushes down on the 1 m2 piston, how much weight can the 10 m2 piston support and lift?   a. 10 N   b. 200 N   c. 100 N   d. 5 N

A man attaches a divider to an outdoor faucet so that water flows through a single pipe of radius 9.25 mm into four pipes, each with a radius of 5.60 mm. If water flows through the single pipe at 1.45 m/s, calculate the speed (in m/s) of the water in the narrower pipes. HINT |m/s Need Help? Read It Watch It

Water has a density of approximately 1- decide if the block will sink or float. em A hollow iron cube measures 5 cm on each side and has a mass of 20g. Will the iron cube sink or float? Objects will sink if their density is greater than water and will float if their density is less. For the following problem, O Float O Sink

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?

Which of the following is NOT true for a ship floating in seawater?   a. The buoyant force is equal to the weight of the ship. b. The buoyant force is greater than the weight of the ship. c. The weight of the displaced water is equal to the weight of the ship. d. The buoyant force is equal to the weight of the water displaced by the ship.
