Explica cómo hacer para evitar resbalarse en un suelo y su explicación en base a la fuerza de rozamiento.
kondor19780726 [428]

Answer:

La fuerza de fricción o rozamiento se define como la que se forma entre dos cuerpos que están en contacto y ocurre al deslizarse entre ellos, la fricción se produce por las irregularidades en sus superficies y esto es un impedimento para el correcto deslizamiento, de este modo, para evitar resbalarse en el suelo se han ideado ajustes en las superficies en contacto, evitando que sean pulidas y se favorezca a las rugosas, el peso que lleve una de las superficies también es determinante puesto que a más peso, aumenta la presión y puede deformar la superficie.

Junto con esto es de tener en cuenta la posición del suelo por el que se transita, un cuerpo va a tender al deslizamiento si se encuentra inclinado por la fuerza de atracción de la gravedad y el peso.

Para evitar resbalarse es necesario evitar superficies lisas, tanto en calzado como en el suelo, preferir superficies horizontales y evitar las declinadas.

When you drop an object from a certain height, it takes time T to reach the ground with no air resistance. If you dropped it fro
alexandr402 [8]

Answer:

Explanation:

Given

When we drop an object from height , suppose h

it takes time T

using equation of motion

h=ut+\frac{1}{2}at^2

where  

h=displacement

u=initial\ velocity

a=acceleration

t=time

here u=0 because it dropped from a certain height

h=\frac{1}{2}gT^2

T=\sqrt{\frac{2h}{g}}

When height is increases to three times of original height

i.e. h'=3 h

then time period becomes

T'=\sqrt{\frac{2\times 3h}{g}}

T'=\sqrt{3}T

Cell is the fundamental unit of life. It is the component of every living organism, creature and being in the biotic environment. Thus, each of this organisms like this panda have cells, which is grouped together to form tissues, and when tissues form together they form the organs and then the organs systems and entirely, as one organism. An entire organism then is what compose species. This hierarchical structure is what every organism is totally composed of. But without the cell –these different types of cells. There would no life.
