The Science of Transportation: Ancient World: The Wheel: • How do they work? Wheels work by rolling along a surface. The curved surface of the wheel reduces the friction between the two surfaces due to a decrease in surface area. With less friction it is much easier to move an object. This is because rolling friction is much weaker than sliding friction. • How did they come to be? The wheel was invented in prehistoric times; as the oldest example of a wheel yet found is from the region of

INTRODUCTION Gas exchange is the movement of respiratory gases across a membrane through diffusion. Diffusion is the process of which the respiratory gases across the gas exchange membrane (oxygen from the environment into the body‚ carbon dioxide from the body to the environment). Using the concentration gradient along the gas exchange surface. For gas exchange to occur these three Features are needed; the gas exchange surface needs to be moist so that the oxygen and carbon dioxide can dissolve

When you think of the ocean‚ you might think of a bottomless blue paradise‚ undisturbed by anything‚ or you might think of happy little fish weaving throughout their pink coral home. However‚ have you ever thought about these little creatures becoming dangerously close to extinction? Or have you even thought about the glorious blue of the ocean turning a muddy brown from all the trash? This is the reality of the deep blue. One major problem arising in the ocean is overfishing. Overfishing is when

Ocean acidification is the ongoing decrease in the pH of the Earth’s oceans‚ caused by carbon dioxide from the atmosphere‚ Seawater is slightly basic (meaning pH > 7)‚ and the process is a shift towards pH-neutral conditions rather than a transition to acidic conditions (pH < 7). Ocean alkalinity is not changed by the process‚ or may increase over long time periods due to carbonate dissolution. An estimated 30–40% of the carbon dioxide from human activity released into the atmosphere dissolves into

function p(t) = −log10t. The variable t represents the amount of hydronium ions; p(t) gives the resulting pH level. Water at 25 degrees Celsius has a pH of 7. Anything that has a pH less than 7 is called acidic‚ a pH above 7 is basic‚ or alkaline. Seawater has a pH just more than 8‚ whereas lemonade has a pH of approximately 3. 1) Create a graph of the pH function either by hand or using technology. Locate on your graph where the pH value is 0 and where it is 1. When y=0 x=1; when y=1 x=0.1 (1‚0)

save these animals by‚ somehow‚ trying to decrease the salinity level? According to the reading passage‚ there are three solutions‚ using desalination facilities to extract water and return to the lake‚ diluting the saltwater using the less saline seawater‚ and dividing the waterbody into sections then manage the relative salinity. The Lecturer refutes each and every one of the solutions with three corresponding criticisms that might jeopardize these plans. Firstly‚ desalination facilities produce

Fukushima in 2011 is the worst miserable thing that happened in the past‚ and this disaster have leaked significant amounts of radiation that have affected ecosystems in the region. On March 21‚ 2011‚ TEPCO (Tokyo Electric Power Company) investigated the seawater near the southern discharge port of the Fukushima Daiichi NPS‚ revealed that radioactive substances significantly exceeding safety standard values were detected.
