Two water pipes of the same length have inside diameters of 6 cm and8 cm. These two pipes are replaced by a single pipe of the same length,which has the same capacity as the smaller pipes combined. What is the inside diameter of the new pipe?

A naval mine is a sphere (V=4/3 Ttr^3 ) of radius 0.5 m that would normally float in water (p_water=1000 kg/m^3 ). The mine (p_mine=700 kg/m^3 ) is held under the surface by a cable that attaches it to the sea floor. a. Find the volume of the naval mine. b. Find the mass of the naval mine. c. Find the tension in the cable that holds the mine under the surface using Newton's Second Law.

Please answer as much as you can! Thank you in advance!   A beachball has a diameter of 24 cm and weighs about 6N. A-What is the volume of the beachball? Then, use this number to calculate the beachball’s average density in kg m-3. B-What is the volume of water displaced by the beachball if it is in the pool? C- Now, using a rope, you tie the beachball to the bottom of the pool so only half of the ball is submerged. What would the diagram look like? D- What is the buoyant force of the tethered beachball? What is the tension on the rope?

UU 2. Water is poured into a U-tube as shown in the A1 Ag Oil A1 A2 figure. The left arm of the tube has cross-sectional area A1 of 10.0 cm2, and the right arm has a cross- sectional area A2 of 5.00 cm2. 150 grams of oil are then poured into the right arm as shown. The two H. liquids do not mix. [Poit = 750 [Answer in kg m 3 significant figures] Water a) Determine the length of the oil column in the right arm of the U-tube. b) Determine the height (H) of the water column in the left arm above the water surface in the right arm?

A small statue is recovered in an archaeological dig. It’s weight is measured to be 96lb, and it’s volume 0.08ft A. What is the statue’s weight density in lbs/ft3? B. What substance is it?

In the process of loading a ship, a shipping container gets dropped into the water and sinks to the bottom of the harbor. Salvage experts plan to recover the container by attaching a spherical balloon to the container and inflating it with air pumped down from the surface. The dimensions of the container are 5.00 m long, 2.35 m wide, and 3.20 m high. As the crew pumps air into the balloon, its spherical shape increases and when the radius is 1.10 m, the shipping container just begins to rise toward the surface. Determine the mass of the container. You may ignore the weight of the balloon and the air in the balloon. The density of seawater is 1027 kg/m³. 434.54 X How does the weight of the container compare to the weight of the water displaced by the container and balloon when the container starts to rise? See if you can express the weight of the water displaced in terms of the density of the seawater and the dimensions of the container and balloon. kg Additional Materials
