Unformatted text preview: 005 10.0 points An empty rubber balloon has a mass oF . 0107 kg . The balloon is flled with helium at a density oF 0 . 18 kg / m 3 . At this density the balloon has a radius oF 0 . 475 m . IF the flled balloon is Fastened to a vertical line, what is the tension in the line? The acceleration oF gravity is 9 . 8 m / s 2 . Answer in units oF N. 006 10.0 points A Frog in a hemispherical pod fnds that he just ±oats without sinking in a ±uid with a density oF 1 . 28 g / cm 3 . IF the pod has a radius oF 5 . 06 cm and negligible mass, what is the mass oF the Frog? Answer in units oF kg. 007 (part 1 oF 2) 10.0 points A sample oF an unknown material appears to weigh 300 N in air and 181 N when immersed in alcohol oF specifc gravity 0 . 727 . What is the volume oF the material? The acceleration oF gravity is 9 . 8 m / s 2 . Answer in units oF m 3 . 008 (part 2 oF 2) 10.0 points What is the density oF the material? Answer in units oF kg / m 3 ....
