A 10 cm * 10 cm * 10cm block of wood with density 700 kg/m^3 is held underwater by a string tied to the bottom of the container. a) What is the tension of the string? b) Will the block float or sink if the string is removed? If it floats and after reaching equilibrium, what will be the volume portion of the block above water surface? c) What should be the mass of a piece of metal put on...
A sphere of cork(density pcork = 240 kg/m^3) is tied to one end of a string and pulled halfway under the surface of seawater(density 1,020 kg/m^3) in a beaker. The other end of the string is tied to the bottom of the beaker. The sphere has a radius of 0.1 m what is the tension in the string
A piece of wood, cut from a magnolia tree, with density ρwood =
572 kg/m3, is tied with a string to the bottom of a
water-filled flask, as shown in the figure.
The wood is completely immersed. The tension in the string is
0.123 N. What is the volume of the piece of wood?

a piece of aluminum with mass 5.5kg and density 2700kg/m3 is suspended from a string and then completely immersed in a container of water. How many newtons is the tension in the string after metal is immersed?
A piece of iron with a mass of 790 g displaces 100 g of water when it is submerged. If we lower the piece of iron under the surface of a lake and then release it from rest, what will its initial acceleration be as it sinks to the bottom of the lake?
Question2 A cylindrical container of height H is full to the brim with water It is placed on a weigh-scale which is then zeroed A light ball made of polystyrene (of density 100 kg/m) of diameter 2 cm is carefully (you can assume there is no unnecessary spilage) and gently pushed down int the water and held beneath the surface of the liquid with a ngid rod of neglible volume as shown in the figure below rigid rod 21 What...
A string of length 8 m and a mass of 90 g is held under a tension of 105 N. A wave travels down the string that is modeled as y(x, t) = (0.01 m)sin[(12.11 m−1)x − (1,170.24 s−1)t]. What is the power (in W) over one wavelength?
