The weight of a metal bracelet is measured to be 0.12200 N in air and 0.07800 N when immersed in water. Find its density.

Expert Solution

The buoyancy force = (0.12200 N - 0.07800 N)

= 0.04400 N.

So Weight of Water displaced = 0.04400/9.8 ( F = ma and a = gravity of Earth )

= 0.00449 Kg

Vollume of Water displaced = 0.00449/ 1000

= 4.49 * 10^-6 m³

Vollume of Water displaced = Vollume of metal bracelet

Mass of Bracelet = 0.12200 / 9.8 Kg

Density = Mass / Vollume

= 0.12200 / (9.8 * 4.49 *10^-6 )

= 2.7726 * 10³ Kg/m³

or = 2772.6 Kg/m³

Archimedes measured the weight of the crown in air to be 11.8 N and its weight in water to be 10.9 N. Was it pure gold?

It is said that Archimedes discovered the buoyancy laws when asked by King Hiero of Syracuse to determine whether his new crown was pure gold (SG = 19.3). Archimedes measured the weight of the crown in air to be 11.8 N and its weight in water to be 10.9 N. Was it pure gold?

“Dry air” is defined as air with no water vapor, and the molecular weight of air, Mair = 28.97 kg/kmol, is for dry air (zero humidity). “Wet air” is typically defined as air with 100% humidity. (a) Calculate the mol fraction of water vapor in wet air at STP conditions. Give your answer in units of PPM to three significant digits. (b) Compare the molecular weight of dry air and wet air at STP conditions. Which air is heavier? Explain....

An irregular lump of an unknown metal has a measured density of 5.63 g/mL. The metal is heated to a temperature of 167 °C and placed in a graduated cylinder filled with 25.0 mL of water at 25.0 °C. After the system has reached thermal equilibrium, the volume in the cylinder is read at 31.9 mL, and the temperature is recorded as 39.5 °C. What is the specific heat of the unknown metal sample? Assume no heat is lost to...

A father (weight W = 858 N) and his daughter (weight W = 372 N) are spending the day at the lake. They are each sitting on a beach ball that is just submerged beneath the water (see the figure). Ignoring the weight of the air in each ball, and the volumes of their legs that are under the water, find (a) the radius of father's ball and (b) the radius of daughter's ball

Why does the weight of an object in the air differ from its weight in a...

Why does the weight of an object in the air differ from its weight in a vacuum (remembering that weight is the force exerted against a supporting surface)? Cite an example in which this would be an important consideration.

Listed below are measured amounts of lead in the air. The EPA has established an air quality standard for lead of 1.5 μg/m3. The measurements shown below were recorded at Building 5 of the World Trade Center site on different days immediately following the attacks of Sep. 11. Use a 0.05 significance level to test the claim that the sample is from a population with a mean greater than the EPA standard. Is there anything about this data set suggesting...
