3. In the figure is cylinder shaped raft made of Lead (ppb = 11,300 kg/m³) with diameter of %3D 14.0 cm and height 3.75 cm. A 3.89 cm X 3.89 cm X 3.89 cm cube of Iridium (pır = 22,560 %3D kg/m³) is suspended by a string from the bottom. The puck and cube are then placed in a tank of Mercury (pHg = 13,600 kg/m³) where they float as shown at rest. a. Draw a free body diagram of the Lead cylinder. Draw a free body diagram of the Iridium cube. Any 3rd law related forces should have the same label. Any forces that are different should have different labels: For example the weight of the cube and puck are different. An example of proper labeling would be: one Wcube and one Wpuck. b. What is the tension in the Lead string supporting the Iridium cube? c. How much of the Lead puck's 3.75 cm height is submerged in the Iridium Mercury? (Note: don't forget to account for the connected cube!) Hg If the cube were set on d. top of the Lead puck, would your answer to part c. be bigger, smaller, or the same? Explain.

Transcribed Image Text:3. In the figure is cylinder shaped raft made of Lead (ppb = 11,300 kg/m³) with diameter of
%3D
14.0 cm and height 3.75 cm. A 3.89 cm X 3.89 cm X 3.89 cm cube of Iridium (pır = 22,560
%3D
kg/m³) is suspended by a string from the bottom. The puck and cube are then placed in
a tank of Mercury (pHg = 13,600 kg/m³) where they float as shown at rest.
a. Draw a free body diagram of the Lead cylinder. Draw a free body diagram of the
Iridium cube. Any 3rd law related forces should have the same label. Any forces
that are different should have different labels: For example the weight of the
cube and puck are different. An example of proper labeling would be: one Wcube
and one Wpuck.
b. What is the tension in the
Lead
string supporting the
Iridium cube?
c. How much of the Lead
puck's 3.75 cm height is
submerged in the
Iridium
Mercury? (Note: don't
forget to account for the
connected cube!)
Hg
If the cube were set on
d.
top of the Lead puck, would your answer to part c. be bigger, smaller, or the
same? Explain.
