Suppose you are a city engineer with the job of exploring the use of more renewable energy in your city or town. Prepare a pamphlet or powerpoint presentation to tell citizens of your city about hydropower, solar power, wind power, and geothermal power and the potential for each one in your city. Your pamphlet or multimedia presentation should include: a definition of hydropower, solar power, wind power, and geothermal power a discussion of the advantages and disadvantages of each a discussion of which one(s) your city should use the most and why how use of renewable energy will impact your city pictures and/or charts and tables to strengthen your argument

What is the molar mass of potassium nitrate, kno3

For a family dinner, jose’s mom baked a loaf of bread. during the meal, his grandmother commented, “this bread is so dense! ” what do you think his grandmother meant by the word dense? you have some ideas regarding density already, but this experiment will enrich your understanding of the relationship between mass, volume and the density of objects. when making measurements in this experiment we will be using si units, the international system of units. the purpose of using si units is to have the ability to communicate and compare data results with other experiments without having to make conversions. measurement symbol si unit length m meter mass kg kilogram volume l liters density kg/l kilograms per liter any calculations that are performed during this experiment will ultimately be reported in scientific notation. recall that scientific notation is extremely important when we have data that is extremely small or large. scientists rely on a standard form of communication to quickly make hypotheses and judgements based on data. what is the density of block a? a0kg/l what is the density of block b? a1kg/l what is the density of block c? a2kg/l what is the density of block d? a3kg/l what is the density of block e? a4kg/l which block is the densest? a5
