Question

To verify her suspicion that a rock specimen is hollow, a geologist weighs the specimen in air and in water. She finds that the specimen weighs twice as much in air as it does in water. The density of the solid part of the specimen is 3.50 × 103 kg/m3. What fraction of the specimen’s apparent volume is solid

Answer #1

To verify her suspicion that a rock specimen is hollow, a
geologist weighs the specimen in air and in water. She finds that
the specimen weighs twice as much in air as it does in water. The
density of the solid part of the specimen is 2.20 × 103
kg/m3. What fraction of the specimen’s apparent volume
is solid?

To verify her suspicion that a rock specimen is hollow, a
geologist weighs the specimen in air and in water. She finds that
the specimen weighs twice as much in air as it does in water. The
density of the solid part of the specimen is 4.13 × 103 kg/m3. What
fraction of the specimen’s apparent volume is solid?

To verify her suspicion that a rock specimen is hollow, a
geologist weighs the specimen in air and in water. She finds that
the specimen weighs twice as much in air as it does in water. The
density of the solid part of the specimen is 4.06 × 103 kg/m3. What
fraction of the specimen’s apparent volume is solid?

A geologist finds that a Moon rock whose mass is 8.78 kg has an
apparent mass of 5.86 kg when submerged in water.
What is the density of the rock?

A person who weighs 550 N empties her lungs as much as possible
and is then completely immersed in water (of density 1000 kg/m3)
while suspended from a harness. Her apparent weight is now 21.2 N.
What is her density?

1.)The Buoyant Force from a fluid to an object depends on which
of the following factors?
a.)The volume of the object
b.)The volume of the fluid
c.)The density of the fluid
d.)The density of the object
2.)Why did the Titanic sink after it hit an iceberg and water
rushed into the hull through the hole created by the
collision?
a.)The density of water has increased
b.)The density of the boat increased
c.)The mass of the boat has decreased
d.)The volume...

A diver is located 63 m below the surface of the ocean (the
density of seawater is 1025
kg/m^3). To raise a treasure chest that she discovered, the
diver inflates a plastic, spherical
buoy with her compressed air tanks. The radius of the inflated
buoy is 0.41 m. If the
treasure has a mass of 215 kg, what is the acceleration of the
buoy and the treasure chest
when they are tethered together and released? The chest is 22 cm...

It is generally a good idea to gain an understanding of the
"size" of units. Consider the objects and calculate the kinetic
energy of each one.
