5) A cylinder of tungsten (mass density 4500 kg/m) has a volume of 0.011 m. When immersed in water (mass density 1000 kg/m”), what is the net force on the tungsten cylinder? (3 points)
As shown in the figure below, 0.5 kg of water is contained within a piston-cylinder assembly at 100°C. The piston has a mass of 90 kg and is free to move smoothly in the cylinder. The local atmospheric pressure and acceleration of gravity are 100 kPa and 9.81 m/s2, respectively. g=9.81 m/s2 Patm = 100 kPa Piston Water at 100°C A = 0.01 m2 For the water, determine the pressure, in kPa, and volume, in cm?
An iron casting containing a number of cavities weighs 23137.8 N in air and 18521.5 N in water. What is the total volume of all the cavities in the casting? The density of iron ( that is a sample with no cavities) is 7.87 g/cm3.
An iron casting containing a number of cavities weighs 23909.1 N in air and 19693.7 N in water. What is the total volume of all the cavities in the casting? The density of iron ( that is a sample with no cavities) is 7.87 g/cm3.
The question refers to a vertical cylindrical beaker holding water. The density of water is 1.0 g/cm3. The volume of a cylinder is πR2H, where R is the radius of the cylinder and H is the height. If the beaker holds 2.47 kg of water and the bottom of the container has a diameter of 5.44 cm, what is the water pressure at the bottom of the cylinder in Pascals (N/m2)?
