Why construction is present near the bulb ​

Physics
1 answer:

7 0

Answer:

The constriction causes the mercury column to break under tension, leaving a vacuum between the bottom of the column and that in the bulb, and the top of the column stays still at the position reached in the body - a "peak hold" system.

Puede ser la suma de dos vectores de distinta magnitud igual a 0
True [87]

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.

Since momentum cannot be changed mid-air, he must decrease his rotational mass in order to increase his angular velocity. To increase his angular velocity the snowboarder tucks in his arms
