  • ️ DEMONSTRATION OF THE PRINCIPLES OF ARCHIMEDES AND PASCAL ⚓️
◻
◻
#Culturacq At the beginning of the video it is observed that a hollow object inside the bottle with water 🔷 is at rest. Newton's first Law states that every body maintains its state of rest or uniform rectilinear motion unless the action of some force↙️ forces it to change it. According to this law we can affirm that the forces that are acting on the object are compensated, that is to say, that the sum of forces applied on the object is equal to zero 0.
◻
◻
As the object is floating on water, a fluid, we use the Archimedean Principle to analyze the forces acting on the body. This Principle tells us that every body submerged within a fluid experiences an upward force called thrust ,️, equivalent to the weight of the fluid dislodged by the body. According to this we can affirm that the forces that act on the upper and lower part of the submerged object are of the same magnitude but opposite: the one that pushes it downwards, the Gravity Force ⬇️ and the one that pushes it upwards, the Force of Push
◻
◻
When pressing the bottle 💢 the object sinks to the bottom and when we stop pressing it goes back up to its initial position, to explain what happened we will see what the Pascal Principle indicates: the pressure exerted on an incompressible fluid and in equilibrium within A container of non-deformable walls is transmitted with equal intensity in all directions ✳️ and in all points of the fluid. When we press the bottle we exert a pressure that is transmitted to the hollow object, which decreases the volume of air inside it, this causes a decrease in the push so the object descends ⏬

  • ⛰ THE MINERALS 🧂
◻
◻
#Culturacq have numerous functions in our body: forming the bones 🦴, regular heart rate, maintain osmotic pressure, form some tissues, help produce certain hormones〽, among others.
◻
◻
Nutritionists divide the essential minerals for human life, in two large groups: Macrominerals such as calcium, phosphorus, magnesium, sulfur, sodium, potassium, chlorine and Microminerals such as iron, zinc, iodine, selenium, manganese 🔘. The difference between these 2 groups lies in the amounts that our body needs to store to maintain an adequate level for its operation 🔁
◻
◻
The best way to obtain minerals is through the consumption of a wide variety of 🥦 food 🥑 or in the case of a deficiency that could lead in the long term to the development of a disease, the consumption of supplements is necessary. However, we must bear in mind that an overdose of minerals can also become toxic 🚫, even if many minerals are sold without a prescription, it is advisable to have a medical control.

  • •Navier-Stokes equation, in fluid mechanics, a partial differential equationthat describes describe the motion of viscous fluid substances. The equation is a generalization of the equation devised by Swiss mathematician Leonhard Euler in the 18th century to describe the flow of incompressible and frictionless fluids. In 1821 French engineer Claude-Louis Navier introduced the element of viscosity(friction) for the more realistic and vastly more difficult problem of viscous fluids. Throughout the middle of the 19th century, British physicist and mathematician Sir George Gabriel Stokes improved on this work, though complete solutions were obtained only for the case of simple two-dimensional flows. The complex vortices and turbulence, or chaos, that occur in three-dimensional fluid (including gas) flows as velocities increase have proven intractable to any but approximate numerical analysis methods.

Euler’s original equation, in modern notation, is ∂u/∂t + u•∇u = - ∇P/ρ

where u is the fluid velocity vector, P is the fluid pressure, ρ is the fluid density, and ∇ indicates the gradient differential operator.

The Navier-Stokes equation, in modern notation, is ∂u/∂t + u•∇u = - ∇P/ρ + v ∆u

where u is the fluid velocity vector, P is the fluid pressure, ρ is the fluid density, v is the kinematic viscosity, and Δ is the Laplacian operator (see Laplace’s equation).
