Puede ser la suma de dos vectores de distinta magnitud igual a 0

Physics
1 answer:
True [87]3 years ago
7 0

Answer:

Falso. Se requiere de dos vectores de igual magnitud pero antiparalelos entre sí.

Explanation:

Un vector es un elemento caracterizado por tener magnitud y dirección, sea \vec v \in \mathbb{R} un vector tal que la resultante sea \vec O (vector nulo). Por Álgebra de los Reales se sabe que todo vector tiene su inverso, es decir, que existe un vector -\vec v tal que:

\vec v + (-\vec v) = \vec O

(v_{x}, v_{y}) + [-(v_{x},v_{y})] = (0,0)

(v_{x}-v_{x}, v_{y}-v_{y}) = (0, 0)

Esto significa, que el siguiente sistema de ecuaciones debe satisfacerse:

v_{x}-v_{x} = 0

v_{y}-v_{y} = 0

Se requiere de dos vectores de igual magnitud pero antiparalelos entre sí. En consecuencia, la anterior afirmación es falsa.

Complete the electron-pushing mechanism for the e1 reaction when 2-methylbutan-2-ol is treated with 20% sulfuric acid.
Sav [38]
E1 reaction works in the mechanism that the removal of an HX substituent results in the formation of a double bond. The E1 reaction for 2-methylbutan-2-ol is shown in the figure. This reaction is called acid-catalyzed dehydration of a tertiary alcohol.

The mechanism works in three major steps:
1. The OH group of the main reactant is hydrated by H2SO4 so it becomes H2O. 
2. The H2O leaves taking electrons with it. This results to a carbocation intermediate on the carbon atom where it was attached.
3. Another H2O protonates the beta carbon. This is the carbon atom next to the carbocation. It will donate its electrons to the neighboring C-C bond, as indicated by the arrow. The carbons are rehybridized from sp3 to sp2, which is a pi bond. As a result, a double bond forms.

The product is 2-methyl-2-butene.

What happens to density when you change temperature of an object?
solong [7]
Most of the substances have higher density in solid state. When we heated solids it change its state to liquid. After a few minutes the liquid will boil and after that it will change to gas. Gaseous state of matter has the lowest density. From this we can conclude that density decreases with increase in temperature.

Note the point: Water has higher density in 4℃, at its liquid state
