Then there would be no acceleration if the velocity of the body is 0.
In a process called “photosynthesis,” plants use the energy in sunlight to convert CO2 and water to sugar and oxygen. The plants use the sugar for food; food that we use, too, when we eat plants or animals that have eaten plants and they release the oxygen into the atmosphere.
So it’s PHOTOSYNTHESIS
Explanation:
Mirrors consist of reflecting surfaces that reflect light.
Reflection is a phenomenon of light wave (but also of other types of waves) in which a ray of light hits a surface, and then it bounces back into the original medium at a certain angle.
The direction of the reflected ray is determined by the law of reflection:
- The incident ray, the reflected ray and the normal to the surface all lie in the same plane
- The angle of reflection is equal to the angle of incidence (where both angles are measured between the ray and the normal to the surface)
A plane mirror is a type of mirror consisting of a straight surface. As a result, light incident perpendicular to the surface is reflected back exactly in the opposite direction.
The image formed by a plane mirror is:
- The same size as the object
- Virtual (it is located behind the mirror)
- Laterally inverted
- Upright
The units of pressure are called derived units because it is derived from base unit, which is distance and a derived unit which is force. Force is derived from acceleration, a derived unit as well, and mass, a base unit; which makes it a derived unit.
There are four layers of these electrons are, s, p, d, and f.
Each one has a certain number of shells, in different shapes, that can hold two electrons.
S- Has one shell, shaped like a circle, so in total can hold 2 electrons.
P- has three shells, shaped like an infinity symbol, so in total can hold 6 electrons
D- has five shells, shaped, err, dunno how to describe it, can hold 10 electrons.
F- has 7 shells, um, even more dunno how to describe it, can hold 14 electrons
There doesn't only have to be one of each shell though. There can be two S levels, and one P level, and no D or F levels.
(search up electron configuration it'll have a chart of the order in which these come in)
Each layer will be stated as Number layer electron number.
For example, the first layer of electron level would be 1, because it's the first layer, S, because that's what the first layer is, and if it was completely filled, 2.
So, 1s2.
If you were going to add another level, which would also be a S level, but it only has one electron, you would say:
2s1,
because it's the second s level and has one electron in it.
And to put the two together, just say:
1s2, 2s1
NOTE: if you were going to add another level, it would be a P level, but it wouldn't be 3p something, it would be 1p something because it is the first electron level.
Another note: if you have three layers of electrons, or just six electrons, you would just say 1p6. (because the P orbital can hold 6 electrons)
Hope this helped!
