The physical properties of the bowling ball is that it is hard, smooth and very dense.
<h3>What are physical properties?</h3>
Physical properties are those properties which are easily observable and which involve only physical changes in a substance.
A bowling ball is a solid.
The physical properties of bowling ball include:
- density- it has high density
- texture- it is smooth
- hardness - it is hard
Therefore, the physical properties of the bowling ball is that it is hard, smooth and has high density.

Answer:
c)The gases have the same average kinetic energy.
Explanation:
As we know that the kinetic energy of gas is given as
here we know that
so we have
now we have
now mean kinetic energy per molecule is given as
so this is independent of the mass of the gas
so average kinetic energy will remain same for both the gas molecules
According to the condensation theory, the most important factor for the formation of our planets was "the interstellar dust attracting heat away from the protosun".
Condensation is the procedure by which water particles noticeable all around bunch together and shape fluid water. This is regularly observed outwardly of cold glasses. This idea additionally identifies with the solar system.
The condensation theory of the solar system expresses that our solar system, and perhaps all other galaxies, were shaped from a cloud of residue and gas that consolidated into strong issue. Space experts trust that the littlest grains of residue in our cloud applied a draw on the gas about it, 'consolidating' into bigger and bigger bits of issue, similarly as a snowball moving downhill will become bigger and bigger. In the long run, the gravitational draw of these residue atoms was sufficiently solid that they started to pull in each other, developing into greater and greater clusters that had more grounded gravitational pulls. In the long run, these bunches of residue and gas from the cloud frame a star, and potentially planets, space rocks, and comets turning about the star.
