Question

Dos ciclistas parten al mismo tiempo, uno al encuentro del otro, en trayectorias perpendiculares entre sí,
con MRU, desde 2 puntos: A y B, separados 1400 m.
El ciclista que parte de A tiene una velocidad de 6 m/s; y el que parte de B, una velocidad de 4 m/s.
¿Cuánto tiempo pasará hasta que los ciclistas se encuentren separados entre sí por una distancia de
400 m?
Escoge 1 respuesta:
Los ciclistas se encontrarán separados por una distancia de 400 m a los 140 s.
Los ciclistas se encontrarán separados por una distancia de 400 m a los 40 s.
Los ciclistas se encontrarán separados por una distancia de 400 m a los 100 s.
Los ciclistas se encontrarán separados por una distancia de 400 m a los 180 s.

Answer 1

Respuesta:

Los ciclistas se encontrarán separados por una distancia de 400 m a los 100 s.

Explicación:

Primero, la distancia que ay entre ellos es de 2m´s por lo tanto los 400 se dividen entre 4 que lo que el otro ciclista lleva atrasado, el resultado es 100.

No me se explicar perdón <3

Answer 2

1). Werner Karl Heisenberg (Würzburg, Germany, December 5, 1901 - Munich, February 1, 1976) was a German physicist. He is best known for formulating the uncertainty principle, a fundamental contribution to the development of quantum theory. This principle states that it is impossible to measure the position and momentum of a particle accurately simultaneously. Heisenberg was awarded the Nobel Prize in Physics in 1932. The Uncertainty Principle had a profound influence on twentieth-century physics and philosophy.

2.

Louis Pasteur (December 27, 1822 - September 28, 1895) was a French chemist whose discoveries were of enormous importance in various fields of natural sciences, especially in chemistry and microbiology. He owes the technique known as pasteurization.

His contributions in organic chemistry were the discovery of the dimorphism of tartaric acid, when observing under the microscope that racemic acid had two types of crystals, with specular symmetry. He was therefore the discoverer of dextro-left and right-handed forms that deviated the plane of polarization of light with the same angle but in the opposite direction.

3. Robert Boyle, (* Waterford, January 25, 1627 - London, December 30, 1691) was an Irish natural philosopher, chemist, physicist and inventor, also known for his writings on theology. He is known primarily for the formulation of Boyle's Law.1 He is widely regarded today as the first modern chemist, and therefore one of the founders of modern chemistry, even though his research and personal philosophy clearly had their implications. roots in the alchemical tradition. Among his works, the skeptical chymist is considered a key work in the history of chemistry.
