Answer all parts! Part A - A cube of side length 21.0 cm floats in oil, 18.0% of its volume is in oil as shown. Use g = 10.0 m/s2. The density of the oil is 900 kg/m3. Compare the volume of the cube Vcube and the volume displaced by oil Vdisplaced. Answers: Vdisplaced = 0.18*Vcube Vdisplaced = 0.5*Vcube not enough information Vdisplaced = 0.82*Vcube Vdisplaced = Vcube Part B - A cube of side length 21.0 cm floats in oil, 18.0% of its volume is in oil as shown. Use g = 10.0 m/s2. The density of the oil is 900 kg/m3. What is the magnitude of the buoyant force on the cube, in Newton? Part C - A cube of side length 21.0 cm floats in oil, 18.0% of its volume is in oil as shown. Use g = 10.0 m/s2. The density of the oil is 900 kg/m3. What is the density of the cube, in kg/m3?

The Zero Gravity Research Facility at NASA-operated Glenn Research Center in Ohio is used to test the behavior of fluids, flames, equipment and other objects in free fall. It consists of a 467-foot long, 12-foot diameter, steel vacuum chamber. The steel chamber resides inside of a concrete lined shaft which extends 510 feet below ground level. Objects falling through the tower experience free fall over a distance of 432 feet (132 meters). a. Determine the falling time for objects dropped from rest.b. Determine the final speed of the objects before the braking period begins.
Pressure cookers have been around for more than 300 years, although their use has strongly declined in recent years (early models had a nasty habit of exploding). How much force (in N) must the latches holding the lid onto a pressure cooker be able to withstand if the circular lid is 21.0 cm in diameter and the gauge pressure inside is 2.60 atm? Neglect the weight of the lid. N

A1.2-m wide cylindrical water tank is filled to the brim. The tank has a hole formed at 13.3 cm above the ground. Water initially leaks out of the hole at a speed 4.2 m.s-1. After some time, it is observed that speed at which water flows out reduces 2.7 m.s-1. During this interval, 3.1 how much water leaked out of the tank, and 3.2 by how much shall the point, at which water lands on
