Question

A 20.4 kg iron mass rests on the bottom of a pool. (The density of iron is 7.86 ✕ 103 kg/m3 and the density of water is 1.00 ✕ 103 kg/m3.)

(a) What is the volume of the iron (in m^{3})?

(b)

What buoyant force acts on the iron (in N)? (Enter the magnitude.)

(c)

Answer #1

A 20.2 kg copper mass rests on the bottom of a pool. (The
density of copper is 8.92 ✕ 103 kg/m3 and the density of water is
1.00 ✕ 103 kg/m3.) HINT Archimedes' principle states, "Any object
completely or partially submerged in a fluid is buoyed up by a
force with magnitude equal to the weight of the fluid displaced by
the object." Click the hint button again to remove this hint. (a)
What is the volume of the copper...

A certain man has a mass of 79 kg and a density of
991 kg/m3 (excluding the air in his lungs).
Calculate his volume in cubic meters.
Find the buoyant force, in newtons, that air exerts on him. Use
1.29 kg/m3 for the density of air.
What is the ratio of the buoyant force to his weight?

One cubic meter (1.00 m3) of aluminum has a mass of
2.70 103 kg, and the same volume of iron has
a mass of 7.86 103 kg. Find the radius of a
solid aluminum sphere that will balance a solid iron sphere of
radius 2.02 cm on an equal-arm balance.

A hammer (mass 0.600 kg) rests on the surface of a table.
What is the magnitude and the direction of the force of the
table pushing on the hammer? If the force acts upward, enter a
positive value and if the force acts downward, enter a negative
value?

As shown in the above figure, a solid object has a density of
1200 kg/m3 and a volume of 8.00x10^-5 m³. It is lowered on a string
into water and completely submerged without touching the container.
The density of water is 1000 kg/m3.
Keep 3 decimal places in all answers. (Don't use scientific
notations.)
Without the string, would the solid object sink in water or
float in water? No submission.
(a) What is the magnitude of the weight (in Newtons)...

An inflated balloon of volume 1000 cm3 is filled with helium.
(a) What is the weight of the balloon? (b) What is the magnitude of
the buoyant force acting on it? (c) What is the magnitude and
direction of the net force acting on it? The density of air is 1.29
kg/m3 , the density of helium is 0.179 kg/m3 , and the mass of the
uninflated balloon is 1.0 g. (There is currently a severe shortage
of helium, so...
