A cube of wood 20cm on each side floats in water so that 7cm is above the surface of the water and 13cm is below. a)What is the density of the wood? ( You must justify your answer) b) How much force would have to be exerted on the wood to submerge it? c) what volume of lead mass has to be placed on top of the block of wood so that it will just be totally submerged? d)Suppose a...

A hydrometer is an instrument used to determine liquid density. A simple one is sketched in the figure below. The bulb of a syringe is squeezed and released to let the atmosphere lift a sample of the liquid of interest into a tube containing a calibrated rod of known density. The rod, of length L and average density rho_0, floats partially immersed in the liquid of density rho. A length h of the rod protrudes above the surface of the...

Pressure and Archimedes' Principle 2. Liquid mercury, which has a density of 13600 kg/m3, is commonly used in barometers to measure air pressure. A U-shaped tube closed at one end contains some mercury at the closed end (see figure) and vacuum above the mercury. Air in the open end exerts pressure on the mercury, and the mercury level rises until the mercury pressure in the closed end equals the air pressure in the open end. The height difference h between...

A mercury U-tube manometer is used to measure the pressure above atmosphere of water in a pipe. The water is in contact with the mercury in the left hand limb. 1. Sketch the arrangement and explain its action. 2. If the mercury is 30 cm below (A) in the left limb and 20 cm above (A) in the right limb, what is the gauge pressure at (A). take specific gravity equal to 13.6. 3. If the pressure at (A) is...

A glass tube of inside diameter 1.0 mm is dipped vertically into a container of mercury, with its lower end 1 cm below the mercury surface. a) What must be the gauge pressure of the air in the tube to blow a hemispherical bubble at its lower end? (Answer: 1400 Pa) b) To what height will mercury rise in the tube if the air pressure in the tube is 3000 Pa below atmospheric? The contact angle is 140 degrees and...

98 *°* When the hydrometer of Problem 48 (Figure 13-34) is placed in a liquid whose specific gravity is greater than some minimum value, the device floats with part of the glass tube above the liquid level. Consider a hydrometer that has a spherical bulb 2.4 cm in diameter. The glass tube attached to the bulb is 20 cm long and has a diameter of 7.5 mm. The mass of the hydrometer before lead pellets are dropped into the bulb...

Saturn's largest moon, Titan is actually larger than the planet Mercury. It is also one of the few bodies in the solar system that has a dense atmosphere. Data from the Voyager 1 probe indicates that the atmospheric pressure on Titan's surface is about 1.60x10^5 Pa, even though free-fall acceleration at Titan's surface is only 1.36m/s^2. Assuming that Titan's atmosphere has a uniform density of 2.32kg/m^3, at what height above the surface is Titan's atmospheric pressure equal to 1.01x10^5 Pa?
