Answer:
There is no kinetic energy.
Explanation:
Since K=1/2mv^2 where m=2122kg and v=0, clearly the car has no kinetic energy as multiplying by 0 results in 0. If the car were moving, there would be kinetic energy.
A star is born when clouds of dust and elements are gathered together in a certain space due to gravity, more and more mass and therefore pressure builds. When the pressure becomes enough to overcome the electronic repulsive force between two hydrogen nuclei, they are forced together and massive amounts of energy are given off forming helium atoms. This energy is then used to fuse other nuclei together. This could be compared to the way human life starts, where instead of 2 nuclei joining together to start a life cycle, two gametes, or sex cells are joined together. Also at the start of both a star and persons life, we are weak and we gain strength until we reach the height of our existence, then humans slowly become less efficient at doing what they do until eventually they cannot sustain themselves any further.
Answer:
The correct option is: 4. its ionization energy decreases
Explanation:
Ionization energy refers to the energy required to pull a valence electron completely from the valence shell of a gaseous atom.
Now, in the <u>periodic table of chemical elements</u>, as we down a group, the atomic radius increases, so the effective nuclear charge experienced by the valence electron decreases. Therefore, the <u>ionization energy decreases</u><u>, down the group.</u>
As we across a period, the atomic radius usually decreases, so the effective nuclear charge experienced by the valence electron increases. Therefore, usually the <u>ionization energy increases</u><u>, across the period.</u>
<u>Therefore, as the atomic radius increases, the effective nuclear charge experienced by the valence electron decreases and thus the ionization energy also decreases.</u>
The best way to deterime which cloth with absorb heat is to put each cloth outside in the heat with a thermometer under it and see which has the highest tempe.
The distance and displacement are both zero.
If you took a photo of Jamie before she started spinning, and another one
after she finished spinning, you couldn't tell the difference in the photos.
Her center of mass never moved, and all of her motion produced no change
in her 'position' (location).
