Un cuerpo se desplaza desde el punto 5,7 m al 7,5 en linea recta. cual es el valor del desplazamiento de la coordenada x?
adoni [48]

Answer:

Δx = 2m

Explanation:

From the given information:

De la información dada:

El desplazamiento ocurrió en un vector que se mueve desde una posición inicial particular hasta el final.

Entonces, supongamos que el desplazamiento es D;

Luego:

D = (7,5 ) - (5,7)

D = (2, -2)

Por lo tanto, el valor del desplazamiento de la coordenada x; Δx = 2m

One day on her walk home from school, Leann noticed some rust on an old car Leann knows that when iron and oxygen chemically rea
Katena32 [7]

Answer:

reactants

Explanation:

The reaction model is given as shown below:

                            4Fe   +   3O₂   →   2Fe₂O₃

The name that describes the iron and oxygen found on the left hand side of Leann's model is reactants.

Reactants in a chemical expression are the species that are combining together to give a product.

Some reactions only have one reactant and such a chemical process is often termed decomposition reaction.

The two moles of Fe₂O₃ is the product of the reaction.

La velocidad de un tren se reduce uniformemente de 12m/s a 5m/s. Sabiendo que durante ese tiempo recorre una distancia de 100 m.
KATRIN_1 [288]

Responder:

Explicación:

Dados los siguientes datos

Valor inicial u = 12 m / s

velocidad final v = 5 m / s

Distancia S = 100 m

Necesario

aceleración del tren.

Usando la ecuación de movimiento

v² = u² + 2as

2as = v²-u²

a = v²-u² / 2s

Sustituyendo los valores dados para obtener la aceleración que tenemos;

a = 5²-12² / 2 (100)

a = 25-144 / 200

a = -119/200

a = -0,595 m / s²

Por tanto, la aceleración del tren durante este período es de -0,595 m / s²

b) Si el tren viaja a una parada desde 5 m / s, su velocidad final será cero y su velocidad inicial u será 5 m / s

Para obtener la distancia durante este período, sustituiremos u = 5 m / s, v = 0 m / sy a = -1,19 m / s² en la ecuación de movimiento anterior;

v² = u² + 2as

0² = 5²-2 (0.595) s

0 = 25-1,19 s

1,19 s = 25

s = 25 / 1,19

s = 25 / 1,19

s = 21,0 m

Por lo tanto, la distancia que recorre hasta detenerse asumiendo la misma aceleración es 21.0 m
