- Liquid helium is stored at its boiling-point temperature of 4.2 K in a spherical container (r = 0.30 m). The container is a perfect blackbody radiator. The container is surrounded by a spherical shield whose temperature is 91 K. A vacuum exists in the space between the container and the shield. The latent heat of vaporization for helium is 2.1 × 104 J/kg. What mass of liquid helium boils away through a venting valve in one hour?A basketball is pressurized to a gauge pressure of PG = 55 kPa when at the surface of a swimming pool. (Patm = 101 kPa). The ball is then submerged in the pool of water which has a density ρ = 1000 kg/m3. Assume the ball does not change in mass, temperature, or volume as it is submerged. Calculate the absolute pressure inside the basketball in kPa when it is at the surface. Write an equation for the pressure difference ΔP between the inside and outside of the ball when it is submerged a distance y below the surface of the water. Solve the pressure equation for the depth (in meters) at which the pressure difference between the inside and outside of the ball will become zero. At this depth the pressure inside the basketball is the same as the pressure outside the ball.デジタル形式で段階的に解決 ありがとう!! SOLVE STEP BY STEP IN DIGITAL FORMAT Structure of Metal Materials: 3.

- Collectible coins are sometimes plated with gold to enhance their beauty and value. Consider a commemorative quarter-dollar advertised for sale at $4.98. It has a diameter of 24.3 mm, a thickness of 1.78 mm, and is completely covered with a layer of pure gold 0.214 µm thick. The volume of the plating is equal to the thickness of the layer multiplied by the area to which it is applied. The patterns on the faces of the coin and the grooves on its edge have a negligible effect on its area. Assume the price of gold is $14.1 per gram. (a) Find the cost of the gold added to the coin. (b) Does the cost of the gold significantly enhance the value of the coin? Yes or No Explain your answer.The Goodyear blimp we usually see hovering above our heads at a football game contains 5400 m3 of helium gas. If there are 1010 kg of gas at an absolute pressure of 1.10 105 Pa in the blimp, what is the temperature of the gas? The atomic mass of helium 4.00260 g/mol.Mrs. smith, a gold miner, intends to smuggle several tons of gold across international borders by disguising it as lumps of iron ore. She commands her engineer workers to form the gold into little spheres with a diameter of exactly 8cm and paint them blue. However, her chief worker points out that customs officials will surely notice the unusual weight of the "iron ore" if the balls are made of solid gold (density 19.3g/cm^3 ). She suggests forming the gold into hollow balls instead (see sketch at right), so that the fake "iron ore" has the same density as real iron ore (5.15g/cm^3 ). One of the balls of fake "iron ore," sliced in half. Calculate the required thickness of the walls of each hollow lump of "iron ore." Be sure your answer has a unit symbol, if necessary, and round it to significant digits.
- A flat piece of glass is supported horizontally above the flat end of a 10.0-cm-long metal rod that has its lower end rigidly fixed. The thin film of air between the rod and the glass is observed to be bright when illuminated by light of wavelength 500 nm. As the temperature is slowly increased by 25.0°C, the film changes from bright to dark and back to bright 200 times. What is the coefficient of linear expansion of the metal?3 / 6 | 100% + | @ 2.

- Solve2. A spherical balloon is made from a material whose mass is 2.90 kg. The thickness of the material is negligible compared to the 1.25 m radius of the balloon. The balloon is filled with helium (He) at a temperature of 300 K and just floats in air, neither rising nor falling. The density of the surrounding air is 1.19 kg/m and the molar mass of helium is 4.0026x10-3 kg/mol. Find the absolute pressure of the helium gas. Pa
