The best transition between the four options presented to represent a time when water molecules are moving closer together would be A. Frost forms on a window pane.
The closest distance that the water molecules can do is when the water is in the state of being solid. It is known that the solid state of matter has the closest distance from molecule to molecule that when a molecule tries to move, the others move as well creating a vibration and thus producing heat in the process. When they are in a liquid state, they are quite far from each other. In a gas state, they really are far from each. This explains the difference in their characteristics.
Hi there!
This is an example of a recoil collision.
Using the conservation of momentum:
The initial momentum is 0 kgm/s (objects start from rest), so:
We are given that the 15 kg block has a velocity of 12 m/s to the left, so:
Solve for v2':
Answer:
The energy that is radiated to Earth by the Sun includes visible light, infrared radiation, ultraviolet radiation, and other types. These different forms of radiation are distinguished based on what property? Sunlight is a mixture of electromagnetic waves, ranging from infrared to ultraviolet.
Explanation:
The noble gases have eight valence electrons and as a result are stable.
If an atom consists of 8 valence electrons, they have a full octet, and do not need to bond, which makes them "happy".
