Question

a
solid cube of wood floats on water with half of its volume below
the waters surface. the same peice is now floated in oil which has
a specific gravity of 0.8. what fraction of the woods volume will
be below thensirface of the oil? still half, more than half or less
than half?

A 500g piece of wood (specific gravity =.5) floats in water
(density=1.0 g/cm^3).
A. What fraction of its volume will be submerged?
B. A 500g iron weight (density = 7.9g/cm^3) is hung from the

A solid cylinder of uniform density of 0.85 g/cm3
floats in a glass of water tinted light blue by food coloring.
Its circular surfaces are horizontal. What effect will the
following changes, each made to the initial system, have on
X, the height of the upper surface above the
water? The liquids added do not mix with the water, and the
cylinder never hits the bottom.
(No change, increase, decrease)
More tinted water is added to the glass.
The cylinder...

Problem 8.3. Cube Floating in Water
A block of unknown material is floating in a bucket of water so
that exactly one third of the block is above the water line and the
remainder is below. The block is a cube with sides of length L.
a.) Without calculation, what can you say about the density of
the block compared to the density of the water, i.e, is it greater
than or less than?
b.) What is the volume of...

A half-cylindrical (semi-circle cross section) solid object
(specific gravity=1.5) is horizontally submerged along its diameter
and rigidly fixed at the ocean floor 10m deep. The semi-circle has
a diameter of 1m and a length of 3m. Assume the specific gravity of
the ocean water to be 1.03 and the unit weight of freshwater to be
9.81kN/m3.
a. compute for the eccentricity of the cylinder.
b. compute for the centroid height of the semi-circle from the
water surface elevation.

A solid cylinder of uniform density of 0.85 g/cm3 floats in a
glass of water tinted light blue by food coloring.
Its circular surfaces are horizontal. What effect will the
following changes, each made to the initial system, have on
X, the height of the upper surface above the
water? The liquids added do not mix with the water, and the
cylinder never hits the bottom.
The cylinder is replaced with one that has the same density and
height, but...

piece of cork is held partially submerged in water by a string
attached to its bottom. The weight of the
cork in air is 20.0 N. The tension in the string is 10.0 N.
(a) What is the buoyant force on the cork? (Newston's 1st
law)
(b) What is the volume of the cork under water? (Archimedes
Principle)
(c) If this volume is 20.0% of the total volume of the cork,
what is the density of the cork?
Oil of...

PLEASE SHOW WORK AND EXPLAIN!
NASA builds a raft made of styrofoam that can just support the
weight of three astronauts without submerging. The weight of
each astronaut is 733 N. Neglecting the weight of the raft
itself, which is very light, what is the volume of the raft?
(a) 0.11 m3
(b) 0.22 m3
(c) 0.44 m3
(d) 1.20 m3
(e) 1.50 m3
QUESTION 40**
The raft is now transported to Mars. After being loaded with the
same three astronauts in the Mars colony...
