Explanation:
A roller coaster travels from the top of the hill to the bottom of the hill. What happens to its energy? Choose all that apply.
- Potential energy decreases
- Potential energy increases
- Kinetic energy increases
- Kinetic energy decreases
- Some potential and kinetic energy is converted to thermal energy by friction.
Answer:
Kinetic energy increases
Explanation:
Kinetic energy is energy that kinda only happens when somethings like moving so if something is moving super fast its kinetic energy is increasing but if something is slowing down from fast to slow its kinetic energy is decreasing that make sense?

Have a wonderful dayThe coefficient used to make the following equation balanced: N2 + O2 → NO is 2.
BALANCING EQUATION:
Balancing an equation means ensuring that each atom of an element on both sides of an equation. To balance an equation, coefficients, which are numbers placed in front of the elements, are used. According to this question, the following equation is given:N2 + O2 → NOTo balance the equation, we make use of coefficient 2 in front of nitrogen oxide (NO) as follows:N2 + O2 → 2NOLearn more at: https://brainly.com/question/11322377?referrer=searchResults

An incandescent light bulb uses 10% of the total energy as light, what happens to the remaining 90% of the electrical energy used by the bulb?
A. The electrical energy is destroyed when it is unused by the bulb.
B. The electrical energy is captured and 90 J are saved for each bulb.
C. The electrical energy is redirected to other electrical appliances in the circuit.
D. The electrical energy is transformed into thermal energy, so the bulb becomes hot.

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 Water Added to Sample

How did James West impact their field? How would things be different in science today if James West had not accomplished what they did?
Hey~ Hope this helps!
{p.s this is hand-written not copied and pasted. Use freely}
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.
Answer all questions pls
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.

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.
