5) a chain is placed around the globe so that it lies taut on the ground (and follows the sea surface). The diameter of the Earth is 12,756 km. a} the chain is extended by 10.0 meters. This means that the chain is no longer tensioned along the ground but can be lifted up. Suppose it is lifted just as much around the entire Earth. How high Iabove where is the chain? b} it you do the same with a chain around the building Globen in Stockholm, what will be the result? The diameter-of the globe is 110 meters. c} What applies to an arbitrary sphere? Write a formula for how the height oi the chain above the surface, h meters, depends on the diameter of the sphere, d meter, and the extension of the chain, tmeter. "i.- Advanced level 16) Anita makes four equal-sized snowballs and puts them in a box where they just fit. Every snowball has a diameter of 12.0 cm. After a few hours, the snowballs have melted. How high is the water level then in the Ashes? Lead: the density 01 water is 0.997 gems, and the density of snowballs is 0.810 gicm3
