Answer:i think they do i dont understand your question it does not make sence
Explanation:
Answer:
the sp³ orbital, is a very directional orbital that forms the bonds called covalent. the material is an electrical Insulator. hardness of the material comes from the energy needed to break the covalent bonds (sp³)
Explanation:
Carbon has several structures, for its different ways of bonding, in all these the orbital s is excited and mixed with the orbitals p, creating hybrid orbitals sp³, sp² and sp, there are some π orbitals around the latter.
Each type of hybrid orbital is linked differently, the sp³ orbital, is a very directional orbital that forms the bonds called covalent, where when it binds to another atom they share an electron, therefore the 4 sp³ orbitals form a stable molecule with full orbitals (8 electrons).
As the electrons are in the direction of the links, they cannot be easily moved, so the material is an electrical Insulator.
The hardness of the material comes from the energy needed to break the covalent bonds (sp³), there are only a few directions in which the links can be separated
Answer: b
. Natural selection is a process that brings about evolution
Explanation:
The natural selection can be defined as the differential survival and reproduction of the organisms that have better phenotypic traits which allow them to survive in their changing environment. These traits are passed on to the next generation this process is necessary for the evolution of the species. The evolution is the change in the structure and function of the organisms with the passage of them.
When a candle burns, you can't hear the flame, and you can't light a light-bulb with it, so you know that there's no sound energy or electrical energy coming from it.
However, if you've ever actually been around a candle while it's in the act of burning, you may have noticed that you can SEE the flame, and if you put your hand close enough to it, you can FEEL the flame and even burn yourself in it. These observations indicate that while the candle is burning, the chemical energy in it is being converted to light energy and heat energy. (choice-C)
Answer:
<em>Si hay rozamiento y el valor de la fuerza de roce es 10 N</em>
Explanation:
<u>Fuerza Neta</u>
La fuerza neta sobre un cuerpo es la suma vectorial de todas las fuerzas actuantes sobre el mismo.
Si conocemos el módulo de la fuerza neta F y la masa m del cuerpo, aplicamos la segunda ley de Newton para relacionarlas con la aceleración a:
Tenemos los datos cinemáticos de la situación, según la cual el cuerpo adquiere una velocidad (desde el reposo) de 4 m/s en 5 s.
Utilizamos la fórmula:
Y despejamos la aceleración:
Podemos calcular la aceleración real que el cuerpo adquiere, producto de una fuerza efectiva igual a:
Si se está aplicando una fuerza de y solo 20 N producen movimiento, entonces se está perdiendo en rozamiento una fuerza:
Si hay rozamiento y el valor de la fuerza de roce es 10 N
