Everyday Science Question Answers - Part 4 of 4 76. Question: Why is a new quilt warmer than an old one? Answer: In a new quilt the cotton is not compressed and as such it encloses more air which is bad conductor of heat. Therefore‚ it does not allow heat to pass. 77. Question: Curved rail tracks or curved roads are banked or raised on one side. Why? Answer: Because a fast moving train or vehicle leans inwards while taking turn and the banked or raised track provides required centripetal

behind the naming of it is that rocks were used to used to carry out arithmetic. This branch of mathematics is able to be rooted all the way back to around 450 B.C.‚ when Zeno of Elea discovered infinite numbers and distances. Later‚ in 225 B.C.‚ Archimedes developed a formula for a sum of infinite series and also created the area of a circle and the volume of a sphere by using "calculus thinking". Not much progress took place until the 17th century‚ Pierre de Fermat looked at parabolas’ maximum and

Early trigonometry The ancient Egyptians and Babylonians had known of theorems on the ratios of the sides of similar triangles for many centuries. But pre-Hellenic societies lacked the concept of an angle measure and consequently‚ the sides of triangles were studied instead‚ a field that would be better called "trilaterometry".[6]The Babylonian astronomers kept detailed records on the rising and setting of stars‚ the motion of the planets‚ and the solar and lunar eclipses‚ all of which required

some ships‚ they are basically metal shells filled with air‚ and are less dense and lighter than the water they push aside‚ which allows the boats to float. http://www.coolquiz.com/ The standard definition of floating was first recorded by Archimedes and goes something like this: An object in a fluid experiences an upward force equal to the weight of the fluid displaced by the object. So if a boat weighs 1‚000 pounds (or kilograms)‚ it will sink into the water until it has displaced 1‚000 pounds

What amounts of corn syrup and sugar make a marshmallow less dense? What’s the problem? What amounts of corn syrup and sugar make a marshmallow less dense? What’s the hypothesis? I am thinking if I mix half a cup of sugar‚ and one third of a cup of corn syrup‚ then that amount of ingredients will make the marshmallow less dense‚ since it is less amounts of corn syrup and sugar. I believe these amounts will make a marshmallow less dense because according to my research‚ the density of corn syrup
