There is relatively little empty space between atoms in solids and liquids, so that the average density of an atom is about the same as matter on a macroscopic scale—approximately 103 kg/m3. The nucleus of an atom has a radius about 10−5 that of the atom and contains nearly all the mass of the entire atom.
(a)What is the approximate density (in kg/m3) of a nucleus?
Answer________ in kg/m3
(b)
One remnant of a supernova, called a neutron star, can have the density of a nucleus. What would be the radius (in m) of a neutron star with a mass 1.3 times that of our Sun (the radius of the Sun is 7 ✕ 108 m)?
Answer ___________ m
What is the density of a substance if 0.071 kg of it occupies 70 X 10-6 m³?
a. 1004.29 kg/m3
b. 1034.29 kg/m3
c. 1014.29 kg/m3
d. 1024.29 kg/m3
e. None of the above
It is known that a cubical object made of cast aluminum 0.254 m on a side contains a hollow cavity also in the shape of a cube but of unknown dimensions. If the mass of the object is 38.7 kg, determine the length of each side of the interior cubical cavity. The density of aluminum is 2.70 103 kg/m3.
