A ball of density 0.6 and volume 1 is floating in a pool of water. At equilibrium, what is the distance from the lowest point of the ball to the surface? (i.e., how far does the ball sink into the water?) Hint: buyoant force, calculate the radius of the ball
Please help!
An inflated, spherical, beach ball with a radius of 0.3573[m] and average density of 10.65[kg/m'] is thrown into a pool of water, where it floats. The density of the water in the pool is 1000.0[kg/m']. What is the volume of the ball that is below the surface of the water, when it is floating in equilibrium? Express your answer in mi
please help!!!
A child playing in a swimming pool realizes that it is easy to pash a small inflated ball under the surface of the water whereas large ball requires a lot of force. The child happens to have a styrofoam ball (he shape of the ball will not distort when it is forced under the surface), which he forces under the surface of the water. If the child needs to supply 581 N to totally submerge the ball,calculate the...
3. What is the density of an object that is 27% submerged when floating in water at 0°C? What percentage of the object will be submerged if it is placed in ethanol at 0° C? Density (kg/m3) Liquid Gasoline 680 Ethanol 790 Oil 850 Water (0°C) 999.87 Water (3.98°C) 1000.00 Seawater 1025
A ball is thrown 45" to the ball's path. What is the velocity of the ball, relative to the ground? horizontally at 7 feet per second, relative to still air. At the same time, a wind blows at 2 feet per second at an angle of Note: For this problem, neglect the effect of gravity on the ball's velocity.] Ifthe wind is blowing the direction of the ball, the velocity, relative to the ground, of the ball is 8.53223 angle...
A 20-cm-radius ball is uniformly charged to 80 nC. A) What is the ball's volume charge density (C/m3 ) ? B) How much charge is enclosed by spheres of radii 5 cm, 10 cm, and 20 cm? C) What is the electric field strength at points 5 cm, 10 cm, and 20 cm from the center?
Pool players often pride themselves on their ability to impart a large speed to a pool ball. In the sport of billiards, event organizers often remove one of the rails on a pool table to allow players to measure the speed of their break shots (the opening shot of a game in which the player strikes a ball with his pool cue). With the rail removed, a ball can fly off the table, as shown in the figure. Pool table...
The density of ice is 0.92g/cm3. An iceberg with a total volume of 300m3 is floating in pure water. Ignore the melting of ice, calculate (a) how much buoyant force is the water acting on the iceberg, and (b) how much volume of the iceberg (in m3, cubic meters) is submerged under water.
A cylinder of length \(L\) and density \(\rho\) is floating in a large tank with water (with density \(\rho_{\mathrm{w}}\) ) and oil (with density \(\rho_{\mathrm{o}}\) ). The cylinder is initially at rest. It is then pushed downward slightly and released, such that it undergoes a vertical oscillatory motion around the initial position. Assume that the fluids are incompressible and inviscid. Throughout the motion, the cylinder is always partially in the water, and partially in the oil.(a) Express the acceleration of...
