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.

Two balls, each with a mass of 0.890 kg, exert a gravitational force of 8.06 × 10−11 n on each other. how far apart are the ball
Bond [772]
This problem involves Newton's universal law of gravitation and the equation to follow would be.

F = GM₁M₂/r²  

Given: M₁ = 0.890 Kg;  M₂ = 0.890 Kg;  F = 8.06 x 10⁻¹¹ N; G = 6.673 X 10⁻¹¹ N m²/Kg²

Solving for distance r = ?

r = √GM₁M₂/F

r = √(6.673 x 10⁻¹¹ N m₂/Kg²)(0.890 Kg)(0.890 Kg)/ 8.06 x 10⁻¹¹ N

r = 0.81 m

Intense temperature and pressure of regional metamorphism

Explanation:

The process that cause the formation of the Vishnu Schist is the intense temperature and pressure as a result of regional metamorphism.

  • Regional metamorphism is an extensive metamorphism of an area as a result of temperature and pressure changes.
  • The schist is a foliated metamorphic rock usually found in areas of moderate to high grade temperature and pressure.
  • The Vishnu schist must have been metamorphosed before the new sediments were deposited on top.

Which of the rolling statement is not true about proper tire care? A. If you see a weaver bar across the width of the tread. B.
skad [1K]
The correct answer should be <span>A. If you see a wear bar across the width of the tread, it's time to change the tire

This is an incorrect sentence because you should change a tire before you see the wear bar. At the time you see the bar, you should've already changed it. </span>

James accelerates his skate board uniformly along a straight road from rest to 10 m/s in 4 seconds. What is James Acceleration?
lawyer [7]

Given:

u(initial velocity)=0

v(final velocity)= 10 m/s

t= 4 sec

Now we know that

v= u + at

Where v is the final velocity

u is the initial velocity

a is the acceleration measured in m/s^2

t is the time measured in sec

10=0+ax4

a=10/4

a=2.5 m/s^2
