Brightest star: Alpha Centauri. Retrograde motion: when Earth’s orbit crosses another planet such as Mars and then it seems as though the planet is going backward then forward again.

Galileo discovers: 4 moons of Jupiter, rings of Saturn, craters of the moon, and phases of Venus. 1st law of motion: objects change if force is applied. 2nd law: acceleration is caused by mass. 3rd law: for every reaction, equal opposite. Refracting telescope: chromatic aberration. Reflecting telescope: modern telescope,

English Language Exams (2019-2023)

Curso 2019-2020

OPCIÓN A: University Education

1)

  1. a) In the… TRUE: “It used to be that a university degree was a fast track to a good career.”
  2. b) There… TRUE: “Men studying English or philosophy may also earn less than the average man who left school at the age of 16.”

2)

  1. Because women earn lower salaries than men, and the jobs to which they have access if they don’t study are even lower.
  2. Yes, you can earn more money if you choose to study certain careers.

Understanding Viscosity and Surface Tension in Fluids

Posted by on Jun 17, 2024 in Physics | 0 comments

Viscosity and Surface Tension

Viscosity and surface tension are fundamental properties of fluids that describe their resistance to flow and their tendency to minimize surface area, respectively.

Surface Tension

Surface tension is the energy required to increase the surface area of a liquid. It arises from the cohesive forces between liquid molecules. These forces cause the liquid to behave as if it has an elastic membrane at its surface.

Liquids with high surface tension tend to form spherical droplets

MODERNISM (1920-1935)

Fragmentation as a reaction against classical patterns, conventions, and tradition. It started before WWI, but it wasn’t until afterward that it developed.

  • Anti-historicist: rejects sequential time (non-chronological), absolute polarities, and the division between past and present (simultaneity).
  • Elitist: a certain level of knowledge is required to understand this movement.
  • Cultural despair: society expected changes after WWI, but this didn’t happen, and they are in chaos and

FINENESS MODULUS OF COARSE & FINE AGGREGATES
Aim: To determination of particle size distribution of coarse aggregates by sieving or screening. Goal and Purpose: Grading refers to the determination of the particle-size distribution for aggregate. Grading limits and maximum aggregate size are specified because grading and size affect the amount of aggregate used as well as cement and water requirements, work ability, pump ability, and durability of concrete. In general, if the water-cement ratio

Perfect Trusses

What is a Perfect Truss?

A perfect truss is an idealized structure made up of interconnected members (usually straight bars or beams) joined at their ends to form a stable framework. In a perfect truss:

  • Members are perfectly rigid and experience only axial forces (tension or compression).
  • Joints are frictionless and perfectly pinned, allowing only forces along member lines.

This simplification helps engineers analyze forces and stresses within the truss, leading to efficient designs for
