Suppose the city wanted to put a nuclear power plant in your community. What would some of the disadvantages be?
:(
Nuclear power plants use uranium as fuel as in nuclear reactions. The process of mining uranium releases high amounts of carbon dioxide into the environment.
What are nuclear reactions?There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.
In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.
In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.

Answer:
James West impacted his field in an abundance of ways. For example, West and Sessler are credited as the inventors of the “foil electret microphone”. Without the creation of this compact microphone over 90 percent of all contemporary microphones – which includes those found in telephones, tape records, baby monitors and hearing aids would cease to exist today.

Soil aeration is a technique that makes holes in the soil. Based on the results of your experiment, how does soil aeration affect the porosity of soil?
Answer:One of the primary reasons that plants need pore space is because oxygen gets stored in the pores. ... Plants absorb water more efficiently when the soil is aerated.

1) How does the cryosphere help regulate Earth's temperature?
2) What kind of organisms are found in oceanic trenches? Describe.
3) Explain how an Estuary can support a wide variety of food webs.
4) List out and describe the factors that help meteorologists forecast weather.
Answer:
1) The cryosphere contains the frozen parts of the planet. This sphere helps maintain Earth's climate by reflecting incoming solar radiation back into space. As the world warms due to increasing greenhouse gases being added to the atmosphere by humans, the snow and ice are melting.
2) Organisms like the Frilled Shark, Giant Spider Crab. Atlantic Wolffish Pair, Fangtooth Fish, Six-Gill Shark, Giant Tube Worms, Vampire Squid, Pacific Viperfish. But there are most likely archaeabacteria which are prokaryotic bacteria or single-celled organisms. A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today.
3) Many different types of plant and animal communities call estuaries home because their waters are typically brackish — a mixture of fresh water draining from the land and salty seawater. This unique combination of salty and fresh water creates a variety of habitats. Estuaries are full of decaying plants and animals. This makes the soil of estuaries rich in nutrients. Because the soil is so rich, lots of different plants grow in estuaries. The plants attract lots of different animals to the estuary and those animals attract other animals to the estuary.
4) Temperature, humidity, precipitation, air pressure, wind speed, and wind direction are key observations of the atmosphere that help forecasters predict the weather. These same factors have been used since the first weather observations were recorded. Observational data collected by doppler radar, radiosondes, weather satellites, buoys and other instruments are fed into computerized NWS numerical forecast models. The models use equations, along with new and past weather data, to provide forecast guidance to our meteorologists. The three main factors of weather are light (solar radiation), water (moisture) and temperature.

Working with one sample at a time, add water to the glass one tablespoon at a time. Water should soak the sample from the bottom up. Count the number of tablespoons of water it takes to bring the water level up to the top of the sample. Record the amount in the chart.
Calculate the porosity of each sample using this formula, and record the results in the table. “Total sample volume” is the amount of soil, sand, or pebbles in the sample. A half cup is equal to 8 tablespoons.
% porosity = (amount of water added to sample ÷ total sample volume) × 100
PEBBLES -
SAND -
SOIL -
Answer:
1. Fill a drinking glass with a cup of water (1 cup =237 ml). Add sugar one teaspoon at a time until you have added 5 teaspoons. Stir and wait until each teaspoon dissolves completely. Between each teaspoon, take a sip and see how “the drink” tastes. After 5 teaspoons you will have added ~ 25 grams, i.e. slightly less than there is in one cup of coca-cola. After how many teaspoons is the drink pleasantly sweet? After how many teaspoons is it way too sweet?
2. Pour half of the sugar-water into a separate drinking class and put it aside for later.
3. To the remaining sugar water solution (~1/2 cup), add small amounts of vinegar, approximately 1/4 teaspoon at a time, taking a small taste after each addition. Keep track of how much vinegar you are adding. How much did you have to add for the drink to taste good to you? Put this glass aside for later comparison.
4. Now fill another drinking glass with half a cup of water (1/2 cup =120 ml), and add the same amount of vinegar that you added to the sugar-water in step 3 in order for it to taste delicious. In other words, you will now have three cups: one with sugar-water, one with sugar-vinegar-water, and one with vinegar-water. Have a taste of the vinegar-water. How does the vinegar-water taste compared to the sugar-vinegar-water drink? To the sugar-water drink?
This is the secret of Coca-Cola! Coca-cola contains a lot of sugar, probably way too much for most people to find tasty. But by adding acid (and some other flavors as well) you can get a tasty drink!
This is an example of the complex ways in which taste molecules can influence each other, and recipes often exploit this fact. By having different flavors play off each other, the crafty cook can adjust the overall flavor experience of a food. This is a similar reason to why some cooks add a bit of sugar to balance out the acidity of tomatoes in a tomato sauce. And Nathan Myhrvold, whom we will hear from later in this course, even goes so far as to add salt to red wine to make it taste better!
Questions:
1. Calculate how many moles of sugar per liter you added to your drink in step 1 before starting to add any vinegar. The molecular weight of sugar (i.e., sucrose) is 342 g/mol, and 1 teaspoon corresponds to approximately 5 grams. Enter your answer to two decimal places, and do not include units.
Teapoons pH 1/4 4.5 2x 1/4 4.2 3x 1/4 4.0 4x 1/4 3.9 5x 1/4 3.8 6x 1/4 3.7 7x 1/4 3.7 8x 1/4 3.6 9x 1/4 3.6 10x 1/4 3.5
2. Calculate the concentration of hydrogen ions in moles per liter in your drink after you added 1.5 tsp of vinegar. You can use the table above which approximates the pH when adding certain amounts of vinegar to water. Enter your answer to one non-zero digit, and do not include units.

3. How many times more sugar molecules are there than hydrogen ions in this drink?
