The reading on a spring balance when a block of wood is suspended from it is 5N. When the block is completely submerged in water, the reading of the spring balance is 1N. A) state the forces that act on the block when it is completely

An incompressible box is completely submerged in water at a depth of 60m. The volume of the box is 8L and it has a mass of 30 kg. The buoyant force on the box is  70N.. If the box is brought to a depth of 90m, stae what the mass of the box ,volume of the box and buoyant force on the box will be? Choose one correct answer with the correct units of measure.   A. Mass = 70kg Volume  = 8L Buoyant force = 30N   B. Mass = 30kg Volume = 8 m3 Bouyant force = 70 pound   C. Mass = 30kg  volume = 8L Buoyant force  =70N   D. Mass = 8 kg Volume = 30L Buoyant force  = 70N

Bird bones have air pockets in them to reduce their weight—this also gives them an average density significantly less than that of the bones of other animals. Suppose an ornithologist weighs a bird bone in air and in water and finds its mass is 45.0 g and its apparent mass when submerged is 3.60 g (the bone is water light) a. What mass of water is displaced? b. What is the volume of the bone? c. What is its average density?

A cube-shaped block A of side length a is hanging from a spring balance D, which reads, in units of mass, Mp. The block is submerged in liquid C, which has a total mass of me and is inside beaker B with mass mp. The beaker rests on an electronic scale E with a readout of ME. a) Draw force diagrams for block A and beaker B. b) What is the mass mд of block A in terms of the given variables? c) What is the density pc of liquid C? d) The block is now pulled out of the liquid. What are the new readings M and Mg on the balance and scale? e) Compare the readouts of the balance and scale before and after the block is pulled from the liquid for the values a = 0.1 m, mg = 1 kg, mc = 5 kg, MD = 3.5 kg, and MĘ = 7.5 kg.

What would be the behavior of an object that was immersed in a fluid if the object and the fluid had the same density? Explain.

When an object is suspended from a spring balance (figure (a)) the reading is 8.80 N. When the suspended object is submerged in water (figure (b)) the reading is 4.40 N. Determine the density of the object. kg/m³ (a) spring scale Mog (b) spring scale FB FRA A TO & Mog
