1. A container is made from a hollcw cube, open at the top, 13.0 cm on a side. It is completely filled with a fluid of density 910.3 kg per cubic meter, Note: 1 atm = 101300 Pascals. a) What is the mass of the fuid in kilograms? b) What is the ABSOUUTE pressure at the bottom surface of the cube in Pascals? c) What is the average force exerted by the FLUID on one of the side walls in Newtons? 2. A ping-pong ball has a mass of 2.413 grams and a volume of 2.873×10A(−5) cubic meters. It floats in a container of water. The density of water is 1000 kg per cubic meter. a) What is the buoyant force acting on the floating ping-pong bati in Newtons? b) Now, push the ball completely underwater. What force is required to hold it completely subenerged under water in Newtons? During a wrestling match, a 158 kg wrestler briefly stands on one hand during a maneuver designed to perplex his adversary. By how much (in m) does the upper arm bone shorten in length? The bone can be represented by a uniform rod 38.0 cm in length and 2.10 cm in radius. Assume Young's modulus for bone under compression is 9×109 N/m2. m [-l10 Points] Consider a hydraulic system, with two connected pistons. If you applied 350 N of force to the small piston (area=10 om 2 , what would be the total force on the farge piston (area 50cm2 )? N [−110 Points] SERCPWAA119.WA.OOE. You can chew through very tough objects with your incisors because they exert a large farce on the small area of a pointed tooth. What pressure in Pa can you create by exerting a force of 360 N with your tooth on an area ef 1.29 mm2 ? Pa
