Ship Tonnage and Measurement Definitions

Classified in Physics

Written on in English with a size of 3.42 KB

Displacement Tonnage

Displacement tonnage is the total weight of the volume of water a ship displaces when it is sitting in the water.


Standard Displacement Tonnage

Standard displacement tonnage is basically the same thing as displacement tonnage, but you must subtract the weight of any fuel and potable water carried on board the ship.


Deadweight Tonnage

Deadweight tonnage is the weight of all the cargo, fuel, dry provisions, supplies, etc. carried on board the ship.

Lightweight Tonnage

Lightweight tonnage is described as the weight of the ship when it was built in the shipyard, including all framing, machinery, decking, etc.

Gross Registered Tonnage

Gross registered tonnage is a measurement of the volume of all enclosed spaces on a ship, with 100

FORCE:

.Any cause with the ability to: modify the state of a 
body ( motion vs rest) and deform a body
1.1 Its effects produced depends on: the intensity,
the point where the force is applied and the
direction and sense
    INERTIA:
.It's the property of the matter to tend to remain
on its state of motion or rest. If a body is resting, it
will continue so eternally unless a force is applied.
     EQUILIBRIUM ALTERATION:
Different forces manage bodies to achieve or lose
equilibrium. Equilibrium types: stable: a slight
disturbance generates a restoring force to return to 
equilibrium. Unstable: a slight disturbance leads to an
increasing departure from the equilibrium. Neutral: A 
disturbance simply moves the object to a new position.

George Orwell: A Life of Social and Political Commentary

Early Life and Influences

Born Eric Arthur Blair in 1903 in British-ruled India, George Orwell's life and works were deeply shaped by his experiences. His early exposure to the rigid social hierarchy and hardships of colonial India, as recounted in his autobiographical essay "Such, Such Were the Joys," fueled his later critiques of social stratification and power dynamics. Orwell's education as a scholarship student amongst England's wealthy elite further solidified his understanding of social inequalities, themes that would later emerge in his novels like "Animal Farm."

From Burma to Literary Pursuits

After graduating in 1921, Orwell joined the Indian Imperial Police in Burma. This experience... Continue reading "George Orwell: Life, Works, and Social Commentary" »

Unlocking Earth's Secrets: A Guide to Fossils, Geological Time, and the Origin of Life

Classified in Physics

Written on in English with a size of 2.64 KB

What Evidence Do Rocks Provide About Life?

Rocks are still an important source of information about many forms of life that existed on this planet.

Why Can Scientists Not Be Sure How Earth Was Created?

Because no rock dates to the formation of the Earth.

How Might Fossil Teeth Reveal an Animal's Diet?

Size and shape indicate diet.

Explain Relative Dating of Fossils

Sedimentary rocks form layers, with newer or younger layers added on top of older layers. This does not tell scientists the exact age of the fossil; however, it does tell the scientist the fossil's age in relation to others above it or below it.

Two More Common Radioactive Isotopes

  • Potassium-40
  • Carbon-14

What Is a Mass Extinction?

It is when many organisms disappear from the fossil record at... Continue reading "Unlocking Earth's Secrets: A Guide to Fossils, Geological Time, and the Origin of Life" »

Understanding Energy: Forms, Transfers, and Sources

Energy: Forms, Transfers, and Conservation

Energy is a fundamental concept in physics, existing in various forms and constantly undergoing transformations. Understanding these forms, how energy is transferred, and its conservation is crucial.

Energy Stores (Forms of Energy)

  • Kinetic Energy: The energy of a moving object (e.g., runners, moving buses).
  • Gravitational Potential Energy (GPE): Energy of an object due to its position in a gravitational field, typically its height (e.g., kites, a ball being thrown).
  • Chemical Energy: Energy stored in chemical bonds (e.g., muscles, batteries).
  • Elastic Potential Energy: Energy stored when an object is stretched or squashed (e.g., an inflated balloon, compressed springs).
  • Magnetic Energy: Energy stored when repelling

Characteristics of new pragmatism mixed focus

Gesture and thinking for speaking (TFS). Slobin proposed
that in the activity of speaking, thinking takes on a particular
quality as experiences are filtered through languages into
verbalized events. He suggested that TFS might not merely
influence how people talk about events, but how they
experience those events. He called this the anticipatory
effects of language, which arise during experience time.
It is during speaking time TFS comes into play,
Thinking for speaking is a particularly compelling area of L2
research with regard to L2 meaning and self-regulation.
McNeill’s research, which links TFS features to gestures, show
that the dialectical interaction between speaking and gesturing
in the GP brings out some semiotic effects that don’t appear
immediately

The Road Not Taken

Robert Frost - 1874-1963

Two roads diverged in a yellow wood. And sorry I could not travel both, And be one traveler, long I stood, and looked down one as far as I could, to where it bent in the undergrowth.

I took the other, as just as fair, and having perhaps the better claim, because it was grassy and wanted wear, though as for that the passing there, had worn them really about the same.

And both that morning equally lay, in leaves no step had trodden black, oh I kept the first for another day, yet knowing how way leads on to way, I doubted if I should ever come back.

I shall be telling this with a sigh, somewhere ages and ages hence, two roads diverged in a wood, and I, I took the one less traveled by, and that has made all the difference.

Understanding Sound: Definitions and Concepts

Sound:

Pressure waves produced when an object vibrates at a frequency between 20 Hz and 20000 Hz and there is a material medium that sound can travel through.

Loudness:

How loud or soft a sound is; loudness is related to the amount of energy that reaches our ears per unit of time.

Pitch:

How high or low a sound is; pitch is related to the frequency of the vibration that produces the sound.

Timbre:

Quality of a sound that makes it different from other sounds of the same pitch and loudness; timbre is related to the shape of the sound wave.

Echo:

Reflection of sound from a surface that is more than 17 m away from the emitter.

Reverberation:

Reflection of sound on a surface that is less than 17 m away from the emitter.

Vibration:

Mechanical oscillation;
