Question

In both cases shown in the diagram below, a block is floating at rest in a liquid. The liquids in the two beakers have the same
density, that is, PA = PB. Both blocks have 55% of their volume below the surface, but the volumes of the blocks are not the same.
Find the mass m2 in terms of V1, V2, and
m1.
Block 1
Block 2

m2 = m1
(等)
m2 = m1
(V2–V1)
m2 = m1
(V2+V1)
m2 = 0.55m1
m2 = 0.45m1

** 12. You have a block of unknown material of mass 18 grams and volume 20 cm3. You have a bucket of water (p filled right to the brim. 1 g/cm3) and a bucket of alcohol (p = 0.79 g/cm3). Both buckets are a) What is the density of the block? b) Which of the buckets, if any, does it float in? Explain your reasoning c) When the block is placed slowly and carefully in the bucket of water, how many cm3 of water spill over the edge? d) When the block is placed slowly and carefully in the bucket of alcohol, how many cm3 of alcohol spill over the edge? e) If you had a 37-gram chunk of this material (the same material as the block), what would its volume be?
P Which of the following statements accurately describes the buoyant force? The buoyant force is the force exerted on an object submerged in a fluid that causes it to sink. The buoyant force is the force exerted on an object submerged in a fluid that opposes its motion. The buoyant force is the upward force a fluid exerts on an object. The buoyant force is the force exerted on an object submerged in a fluid that is equal to the weight of the object. 4 UNANSWERED 5:47 15:57 QUESTION 1/4 ㄒㄧ→ Clemson Univers

A length of clear plastic tubing is bent into a vertical U, as shown in the figure, and two liquids that do not mix are poured into it. Liquid A, with density ρA continues from the left column into the right. Its height is d1 in the left column and d2 in the right column. Liquid B, with density ρB, sits on top of liquid A in the right column. Its height is d3 above liquid A. a) Enter an expression for the density of liquid B, in terms of the other defined quantities. b) Calculate the density of liquid B, in kilograms per cubic meter, if liquid A has a density of ρA = 1.6×103 kg/m3, and d1 = 11.8 cm, d2 = 7.2 cm, d3 = 6.3 cm.

A raft has dimensions 7.0 m x 7.0 m with a thickness of 1.0 m and made of material with average density 650 kg/m3. a. When floating in water, what percentage of the volume is under water? b. What is the pressure underneath the raft? c. How heavy of a load is necessary to cause the raft to be 80% submerged in water? d. If the raft is made with a different material of lower density and 80% of it is still submerged, how if at all would your answers to (a), (b) and (c) change? e. , explain how, if at all, the answer to (b) is related to the buoyant force. f. Imagine that the load increases enough to fully submerge and then sinks the raft to the bottom of the lake. How, if at all, does the buoyant force vary during this process?
