An unknown object is suspended from a thin string and fully submerged in a container of water. Water surrounds the entire object as it hangs from the string, and the object is not touching the bottom of the water filled container. The object remains at rest at all times. The density of water is 1000 kg/m3. a) Draw a FBD using the unknown object as your system. Be sure to label the forces. b) The unknown object has an unknown mass M. The tension in the string is measured to be (3/5)M g. Calculate the density of the unknown object.

3. The specific gravity of a certain alcohol is 0.8. Calculate its specific weight and mass density (in both English and SI units)  (3 DECIMAL IN FINAL ANSWER PLS!!)

At the surface of a freshwater spring, a manatee with a small amount of air in its lungs is neutrally buoyant. The manatee now dives to a depth of 10 m. At this greater depth, the buoyant force isA. Less than the weight force.B. The same as the weight force.C. Greater than the weight force.

4. Pick three different whole numbers of ounces of beverage for Alice to drink and find her height after consuming each amount. Assume in each case that she starts out 5 feet tall.

Question 3 Calculate the dry rodded unit weight (density), apparent specific gravity, bulk specific gravity oven dry, and bulk specific gravity at SSD for the following two aggregate samples. a) An aggregate sample from a stockpile A has a mass of 35.09 lb. When oven-dried, it has a mass of 33.14 Ib. When brought to a saturated surface dry state it has a mass of 35.18 Ib. When weighed in water, it has a mass of 20.23 lb. A 0.35 ft.³ bucket filled with an oven-dry sample of the aggregate weighs 33.14 lb. b) An aggregate sample from a stockpile A has a mass of 8.93 kg. When oven-dried, it has a mass of 7.4 kg. When brought to a saturated surface dry state it has a mass of 7.87 kg. When weighed in water, it has a mass of 4.35 kg. A 0.009 m.3 bucket filled with an oven- dry sample of the aggregate weighs 13.9 kg.

State Pascal’s principle and give one application of the principle. An object is dropped into a beaker of water. Two forces are operating on the object viz. the weight of object and the buoyant force FB due to the fluid. Explain, in terms of the forces when the object. a.)  Sinks to the bottom of the beaker      b.)Floats in the water A hydraulic press for compacting powdered samples has a large cylinder with a diameter of 10.0 cm and a small cylinder of diameter 2.0 cm. If a force of 350 N is applied to the small cylinder, what will be the force exerted by the fluid on the large cylinder? Be consistent with your units.

1.An open rectangular tank mounted on a truck is 5m long, 2m wide and 2.5m high is filled with water to a depth of 2m.   b)Determine the accelerating force on the liquid mass.
