A helium balloon is used to lift a load of 106 N. The weight of the envelope of the balloon is 51.5 N and the volume of the helium when the balloon is fully inflated is 33.9 m3. The temperature of the air is 0°C and the atmospheric pressure is 1.00 atm. The balloon is inflated with a sufficient amount of helium gas that the net upward force on the balloon and its load is 30.6 N. Neglect any effects...

A helium balloon is used to lift a load of 100 N. The weight of the envelope of the balloon is 45.0 N and the volume of the helium when the balloon is fully inflated is 31.8 m3. The temperature of the air is 0°C and the atmospheric pressure is 1.00 atm. The balloon is inflated with a sufficient amount of helium gas that the net upward force on the balloon and its load is 31.2 N. Neglect any effects...

A spherical balloon filled with helium gas must lift a1.00-kg scientific payload off the ground, and the mass of the empty balloon is 0.500 kg. The mass densities are 1.286 kg/m3 for air, 0.179 kg/m3for helium gas, 1.251 kg/m3 for nitrogen gas. Part A What is the minimum diameter of the balloon? Express your answer with the appropriate units. d = SubmitMy AnswersGive Up Part B A helium shortage forces the scientists to consider using nitrogen gas in the balloon....

Balloons are often filled with helium gas because it weighs only about one seventh of what air weighs under identical conditions. The buoyancy force, which can be expressed as Fb Pairg Vballoon. will push the balloon upward. The balloon has a diameter of 9 m Assume the density of air is ρ 116 kg/m3 and the density of helium gas to be 1/7th of this Neglect the weight of the ropes and the cage. Determine the maximum amount of Joad,...

4) A cylindrical can (radius 10 millimeters) is used to measure rainfall in Stormville. The can is initially empty and rain enters the can during a 60-day period. The height of water in the can is modeled by the function S, where S(t) is measured in millimeters and t is measured in days for 0sts 60. The rate at which the height of water is rising in the can is given by S'(t) = 2 sin(0.03t) of the 60-day period?...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
