Fire Ants Create Floating Rafts to Face Flooding Mounds of fire ants can be found floating around waters in South Carolina. It is part of the tiny insect’s way of surviving the floods that have affected the state. In a video captured by WSAV 3 photojournalist Chris Murray‚ the ants are shown in a mound floating on top of flood waters near Charleston. WSAV 3’s reports that the ants use their claws‚ jaws and sticky pads on their legs to stick together. There is an oily fluid that keeps them on a

STABILITY OF FLOATING BODIES (White pp 92 – 95) A floating body is STABLE if‚ when it is displaced‚ it returns to equilibrium. A floating body is UNSTABLE if‚ when it is displaced‚ it moves to a new equilibrium. Consider a floating body tilted by an angle ‚ as shown below. For the untilted body the point G is the centre of gravity of the body where the body weight‚ W‚ acts. The point B is the centre of buoyancy (the centroid of the displaced volume of fluid) where the upward buoyancy force

the 1930’s the time when this story takes place‚ men are usually the ones working for the money‚ and performing all the hard labor‚ while women are supposed to do all the house work‚ and behave in a polite manner. In the story "Boys and girls" by Alice Munro the protagonist struggles with societies ideas of how a girl should be. This story is about a girl who prefers helping her father with chores on the field as opposed to helping her mother in the kitchen. As the story progresses her mentality changes

Floating Exchange Rate Exchange rates between currencies have been highly unstable since the collapse of the Bretton Woods system of fixed exchange rates‚ which lasted from 1946 to 1973. Under the "floating" exchange rates‚ since 1973‚ exchange rates are determined by people buying and selling currencies in the foreign-exchange markets . The instability of floating rates has surprised and disappointed many economists and businessmen‚ who had not expected them to create so much uncertainty.

story “The Interlopers” by H.H Munro exemplifies that individuals never know what life has in store‚ so it is important to let go of grudges and make peace before it’s too late. Primarily‚ life goes up and down‚ and you will never know what the future holds. For instance‚ in the beginning of the story the narrator reveals that Ulrich Von Gradwitz and Georg Znaeym have bad blood‚ “If there was a man in the world whom he detested and wished ill to it was Georg Znaeym”(Munro 34).However‚ later on because

Analysis Response: Biology‚ Race‚ and Floating Signifiers In the video‚ Race: The Floating Signifier‚ Stuart Hall counters the thought that race is connected with the biological aspect. Rather than considering race as due to the biological make up of an individual‚ it is a collection of characteristics brought together that forms one ’s race. That is how Stuart Hall views race‚ as a floating signifier‚ something that is ever changing and not static. This paper will discuss the troubles of using

The floating egg experiment – How much salt is needed to make an egg float? Aim: To investigate the effects of salt on the density of water (and therefore the ability to float an object in said water) and to find the amount of salt needed to float one regular egg in a glass of water. Research: Internet research shows that adding salt to water increases the density‚ and in turn makes it easier for objects to float. 4-10 teaspoons of salt in 1 glass of water is said to be enough to make one egg
