Answer:
e. B and C
Explanation:
When the sun ignited in our solar system evaporation of the material closest to the sun took place. The low density material were pushed further. The rocks that remained formed the protoplanets. As, the early solar system was very hot parts of the protoplanets melted. This caused the melted material to flow towards the center of the planet. As the mass of the planet increases this causes more accretion which causes materials of different densities to mix.
The definition is a nuclear reactor that generates more fissile material than it consumes.
<h3><u>Answer;</u></h3>
4. the material the object is made of and the color of light that strikes it
<h3><u>Explanation;</u></h3>
- The color of an object is the wavelength of light that the object reflects, which is determined by the arrangement of electrons in the atoms of the material making the object.
- <em><u>We could therefore say that the color of object depends on or is determined by the material making up the object as this determines the the wavelengths of light the object reflects. Lastly, the color of light source also determines the color of the object.</u></em>
Answer:
A) Does not change
B) Decrease
C) Increasing
D) Increasing
Explanation:
When it pushes it's volume is reduced by 1/3 because it's Area is constant there for only volume is decreased. Then the number of molecules don't change
A) don,t change
B) Decreases
C) Density is increased because it mass doesn't change. there for
Mass = Density * Volume
When Volume is decreasing to keep mass constant Density will be increased.
D) Pressure is increased according to the boil's law. it says that for fixed mass and fixed temperature pressure is inversely proportional to the volume. then volume decrease pressure increase
