Question

does an object have greater density in the air than if it submerged in the water?

Answer #1

A
certain object has a density just slightly less than that of water
so that it floats almost completely submerged. However, the object
is more compressible than water. What happens if the floating
object is given a slight push to submerge it?

The density of lead is greater than the density of iron. If two
objects of the same volume, one made of solid lead and one made of
solid iron, are submerged in water the buoyant force will be
greater on the

Does the density of a block of wood and ice have to be less than
the density of water in order to float (i.e. not be completely
submerged)? Explain.
Please have clear hand writing.

an object weighs 205 N in the air and it weighs 125 N when
totally submerged in water.
Part A: determine density of object ?
(.......kg/m^3)

thanks)

an object has a mass of 10g when weighed in air. The same object
has a mass of 2g when weighed in water. what percent of the object
is submerged and what is the density?

An object is suspended from a mass balance. When the object is
surrounded by air, the mass balance reads 150 g. When the object is
completely submerged in water, the mass balance reads 90 g. a) What
is the volume of the object? b) What is the density of the object?
c) The same object used in problem 1 is completely submerged in an
unknown liquid. If the mass balance reads 75 g, what is the density
of the unknown...

1.The observer is in air nearly above the object submerged in
water (index of refraction 1.33). The depth of the object is 4.5cm.
Find the apparent depth of the object. (Hint: Use Snell’s law
of refraction and the fact that the angles of incidence and
refraction are small, so tan θ ≈ sin θ.)
2.When a diverging lens is held 10.9 cm above a line of print,
the image is 3.1 cm beneath the lens. (a) Is the
image real...

Some fish have a density slightly less than that of water and
must exert a force (swim) to stay submerged. What force (in N) must
a 59.0 kg grouper exert to stay submerged in salt water if its body
density is 1017 kg/m3?

An object with a density of 2500 kg/m3 weighs 245 N in air and
125 N when fully submerged into a liquid. Find the density of the
liquid.

An object made of a single atomic element weighs 2.6000
N in air and 1.6370 N when completely submerged
in water.
1. Calculate the density of the object.
2. What is the chemical symbol of the atomic element?
