weight greater in air than in the liquid. Therefore‚ it is easier to lift a body in a liquid than in the air. ii. Steel balls sink in water but don’t sink in mercury. Why? ~ The density of the water is less than that of mercury. Also‚ the density of the steel is greater than that of water but less than that of mercury. Hence‚ mercury provides greater upthrust than water does resulting the floatation of the steel in it. iii. A body floats in a liquid contained in a beaker. The whole system

more than a century. In fact‚ the first written record of amalgam being used in dental applications is 1528 .Yet‚ it is still a very commonly used material today. Amalgam was first made by melting down Spanish or Mexican coins and mixing them with mercury . When it cooled and settled into the cavity‚ it actually turned black. Bell then evolved this rudimentary procedure into a more controlled alloy in 1819. The substance created a massive wealth for the dental surgeons who promoted its use. However

‘you think you have been lodged with the devil incarnate’ (Bradford health-General‚ no date) this gives the impression that he would rather be residing or is the same as hell because of the immense disease and vile stench.

RELAY A relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism mechanically‚ but other operating principles are also used. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits)‚ or where several circuits must be controlled by one signal. The first relays were used in long distance telegraph circuits‚ repeating the signal coming in from one circuit

McCarthy‚ linking the vaccinations to the time their child started developing symptoms of autism. Early on‚ questions were raised about the mercury in the vaccinations. Since then‚ the mercury has been taken out of the vaccines but autism still continues to rise. In her interview with Time magazine‚ Ms. McCarthy stated "We don’t believe it’s only the mercury. Aluminum and other toxins also play a role. The viruses in the vaccines could be causing it‚ too." I found a study published in 2011‚ in

Women went to extreme measures to achieve these ideal characteristics‚ plastering their faces with white cream and covering their cheeks in rouge (Leed). A fully made-up woman in Shakespearean times would look rather ridiculous today‚ and even Shakespeare criticizes “ideal” beauty in one of his sonnets‚ Sonnet 130: My
