My English Public speaking course teacher instructed me to make a Informative  speech about " Some popular shipwrecks at the bottom of the sea" The speech should be about 4-5 minutes long( approximately 500-600 words). Please make the speech at your own words . I will rate you positive if you do so. Thank you so much."

One mole of Gold (Au) atom has a mass of 197 g. We know that the density of gold is 19.30 g/cm3 in room temperature. Using those numbers, answer the following questions: a) What is the mass of a single gold atom in kg? b) Assume that gold atoms sit in a perfect cubic crystal structure. Estimate the distance between two gold atoms in meters.   c) If we have a gold cube of 6 cm on each side, how many atoms can we fit along the edge of each side of the cube?  d) What would be the mass, in kilograms, of the gold cube we discussed in part (c) (measuring 6 cm on each side)?

Still think that unit conversion isn't important? Here is a widely publicized, true story about how failing to convert units resulted in a huge loss. In 1998, the Mars Climate Orbiter probe crashed into the surface of Mars, instead of entering orbit. The resulting inquiry revealed that NASA navigators had been making minor course corrections in Sl units, whereas the software written by the probe's makers implicitly used British units. In the United States, most scientists use Sl units, whereas most engineers use the British, or Imperial, system of units. (Interestingly, British units are not used in Britain.) For these two groups to be able to communicate to one another, unit conversions are necessary. The unit of force in the SI system is the newton (N), which is defined in terms of basic Sl units as 1N=1 kg -m/s?. The unit of force in the British system is the pound (lb), which is defined in terms of the slug (British unit of mass), foot (ft), and second (s) as 1 lb = 1 slug · ft/s?.…

The World Health Organization differentiates bone diseases using bone density measurements. The table given below is the criteria for diagnosing different bone diseases (assuming that the mean normal bone density is 1.8 g/cm and that 1SD is approximately 10% of the mean bone density). CATEGORY Osteoporosis Osteopenia (Low Bone Mass) 1.98 g/cm3 Normal Bone Density 1.98 Osteopetrosis What would be the diagnosis of a bone sample if its weight in air is 52 grams and its weight in water is 20 grams?

A typical bathroom sink faucet releases about two gallons of water every minute.   a) If it takes you 2.5 minutes to brush your teeth and you leave the water run for the entire time, how much water would be used? b) If you only run the water for 30 seconds, how much water would be used?

You have an 18-carat gold coin (an alloy of gold and copper). Its mass is 6 grams. Using the fact that the number of carats is equal to (24*mass of gold/total mass), calculate the volume of gold in the coin. (density of pure gold = 19300 kg/m3, density of copper = 8960 kg/m3.) a.) 1.68*10-7 m3 b) 2.33*10-7 m3                c) 4*10-7 m3.   In the problem above, what is the density of the coin? a.) 14963 kg/m3 b) 12333 kg/m3                c) 19300 kg/m3
