Volume of this spherical vessel : V = 4/3 πr³ = 4/3 (2/1 cm)3 = 4.189 cm3
Density of this spherical vessel shall not exceed 1 g/cm3 :
thus mass of spherical vessel if density is 1 g/cm3 = 4.189 g
mass of empty vessel = 2.0 g
Thus, ,max. mass of water can be added : 4.189 g- 2.0 g = 2.189 g
thus greatest volume of water that can be placed = 2.189 mL ~ 2.18 mL

Help please
Archimedes Principle states that an object will float if the weight of the water it displaces is equal or greater than the weight of the object. Weight is multiplied by the due to and mass is multiplied by So after equating the two weights, the constants of and divide out. In practice, this means an object will float if itsis equal to or than the of the Sources of Error A Vernier Caliper good to :0.02 mm was...

Many people have imagined that if they were to float the top of a flexible snorkel tube out of the water, they would be able to breathe through it while walking underwater. However, they generally do not consider just how much water pressure opposes the expansion of the chest and the inflation of the lungs. Suppose you can barely breathe while lying on the floor with a 370 N weight on your chest. How far below the surface of the...

5) A boy uses a wine bottle cork as a fishing float. The cork has a diameter of 20.0 mm, a length of 40.0 mm and a relative density of 0.460. Determine: a) the volume of water the cork displaces while floating on its own in fresh water; b) the maximum mass of spherical lead sinker which the cork can support before it sinks completely (ignore the volume of the small steel hook and fishing line).

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...

A wooden block of volume 5.26 times 10^-4 m^3 floats in water, and a small steel object of mass m is placed on top of the block. When m = 0.400 kg, the system is in equilibrium and the top of the wooden block is at the level of the water. (Take the density of steel to be 8 g/cm^3.) (a) What is the density of the wood? kg/m^3 (b) What happens to the block when the steel object is...

Help me, Please
In this Virtual Lab, you will find the mass of an object using an electronic balance. You will then predict if an object will float by comparing its mass to the mass of the water displaced by the object. To do this Virtual Lab, you will need to convert the volume of the water displaced from milliliters (mL) to grams (g). The mass of 1 mL of fresh water is 1 g. If you know the volume...
