The density of ice is 917 kg/m³, and the density of sea water is 1025 kg/m³. A swimming polar bear climbs onto a piece of floating ice that has a volume of 4.47 m³. What is the weight of the heaviest bear that the ice can support without sinking completely beneath the water? Number Units
The density of ice is 917 kg/m3, and the density of sea water is 1025 kg/m3. A swimming polar bear climbs onto a piece of floating ice that has a volume of 3.21 m3. What is the weight of the heaviest bear that the ice can support without sinking completely beneath the water in Newtons.
The submersible diving chamber has a total mass of 5300 kg including personnel, equipment and ballast. When the chamber is lowered to a dept of 1300 m in the ocean, the cable tension T is 7 kN. Compute the total volume V displaced by the chamber. Use the density of salt water: ?salt water = 1.03 x 103 kg/m3
A diver is located 63 m below the surface of the ocean (the density of seawater is 1025 kg/m3). To raise a treasure chest that she discovered, the diver inflates a plastic, spherical buoy with her compressed air tanks. The radius of the buoy is inflated to 0.41 m. If the treasure has a mass of 215 kg, what is the acceleration of the buoy and the treasure chest when they are tethered together and released? The chest is 22...
If your body has a density of 985 kg/m^3, what fraction of you will be submerged when floating quietly in the following liquids? fresh water ____________ % the Great Salt Lake, which has a density of 1030 kg/m^3 ____________ %
A 20 kg piece of metal displaces 7.8 L of water when submerged. Find the density (kg/m^3) A 2.3 m-tall barrel is filled with water (with a weight density of 2127N / (m ^ 3) ). Find the water pressure (in kPa) on the bottom of the barrel Find the force of gravity between a object (mass = 2.9 kg) and another planet (mass=7.6*10^ 23 kg) when the planet at its closest to Earth \ d/stance=1.2 x 10^ 10 m)...
Chloe has a vertical velocity of 3 m/s when she leaves the 1 m diving board. At this instant, her center of gravity is 2.5m above the water A. How high will Chloe go? B. How long will Chloe be in the air before she touches the water? Assume that she first touches the water when her center of gravity is 1m above the water.
A crane lifts a statue from the ocean with a cable. The statue's density is 2700kg/m^3 and it's mass is 2000kg. What is the torque of the cable when: a) it lifts the statue while it's still underwater (density of ocean is 1025 kg/m^3) b) the statue is completely out of the water?
Problem A 5-m container is filled with 850 kg of granite (density 2300 kg/m) and the rest of the volume is air with density 1.15 kg/m2. Find the mass of air and the average specific volume. Problem 3 A tank has two rooms separated by a membrane. Room A has 1 kg air and volume 0.45 m3. Room B has 0.8 m air with density 1.6 kg/m3. The membrane is removed, and the air comes to a uniform state. Find...
A 2.18-m-long diving board of mass 13.2 kg is 3.00 m above the water. It has two attachments holding it in place. One is located at the very back end of the board, and the other is 25.0 cm away from that end. (a) Assuming that the board has uniform density, find the force acting on each attachment. {435 N, upward, 565 N, downward} b) If a diver of mass 69.3 kg is standing on the front end, what are...
