How are seatbelts related to inertia? Write you answer in complete sentences.
I need answer asap!!!
Answer:
Inertia- the tendency of an object to resist a change in velocity
Explanation:
Say a car was going at 65 MPH, but suddenly stopped. For all of the people in that car, their bodies would keep moving forward at 65 MPH until stopped by an equal force (say, the thing right in front of each person) The seatbelt is there to protect you from your own inertia.

What is the name of the tide when the sun, moon, and earth are all aligned, causing the greatest pull for highest and lowest tides?
Question 10 options:
Low tide
Spring tide
High tide
Neap tide
Answer:
spring tide
Explanation:
When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides — both commonly called spring tide
Answer:
Whenever the earth, moon and sun are aligned, the gravitational pull of the moon is augmented by the gravitational pull of the sun, causing larger than average tidal ranges — meaning especially high high tides and very low low tides. These extreme tides are called “spring tides.”

Answer: C, the number of atoms stay the same
Explanation:
The number of atoms remains the same before and after the reaction. This is because of the Law of Conservation of Mass, which states that matter cannot be created or destroyed in a chemical reaction. In the case of methane burning, one molecule of methane (CH4) reacts with two molecules of oxygen (O2) to produce one molecule of carbon dioxide (CO2) and two molecules of water (H2O). The total number of atoms on both sides of the equation is conserved.

Use each of these terms correctly in your description:
• community
• ecosystem
• biotic
• population
• individual
• abiotic
Answer:
this is an answer for YOU to answer. this is about YOUR ecosystem
Explanation:
just say what it's like, is it a community? is it populated? explain.
Through all the food chain, food web, chemical cycles, etc., biotic and abiotic forces interact within an ecosystem. Therefore, the functional and structural unit of nature is the ecosystem.
What is ecosystem?The functional and structural unit of nature is the ecosystem. This relationship between living and nonliving elements is handled by the ecosystem. All living things, including plants, animals, and microorganisms, rely on non-living substances to survive and keep the natural world in balance.
Individual, population and community play important role in running a ecosystem. Terrestrial Ecology: A terrestrial ecosystem is an ecosystem that is found on land. Grassland, desert, and tundra ecosystems, for instance.
Therefore, the functional and structural unit of nature is the ecosystem.

An object has a mass of 960 g and a volume of 15cm3 what’s the density?
Explanation:
density = mass ÷ volume
mass = 960g
volume = 15³ = 15 × 15 × 15
= 3375 cm
density = 960 ÷ 3375
= 0.28 g/cm³
In this project, you will practice calculating work and speed using the proper formula. You will also use a data table to record and analyze your data. For each question, you will complete a row in your data table to record the details, and your results. Don't forget to use proper units of measurements in all of the parts of your table!

Sheila and Jerome are lab partners. They have the following materials at their table:
1 square of aluminum foil, 1 stirring rod, 1 beaker of water, 1 scoop of copper II chloride salt (blue color)
Step 1:Jerome adds all the salt to the water and stirs. The salt crystals disappears and the liquid solution turns a clear blue.
Step 2: Sheila tears up the aluminum foil into small pieces.
Step 3: Jerome dares her to put the foil in his beaker. They see the edges of the foil turn a rusty orange. As they stir, the beaker becomes warm to the touch and a vapor begins to rise from the surface of the beaker. Within a few minutes, the foil has disappeared and the liquid is now clear. There are orange-rust colored flakes floating in the liquid.
Q: Jerome claims that when the salt was added to the water it turned blue and the foil disappeared, these were chemical changes. He went on to explain that the chemical change was due to the fact that the atoms were speeding up. Sheila disagrees claiming that 1 is a physical change and 1 is a chemical change and Jerome’s evidence is incorrect. Who is correct, Jerome or Sheila? Write a scientific explanation (CER) to support your argument.

List the communities in a successional sequence of secondary succession?
The given communities can be ordered in the secondary succession as grass, shrubs, small trees and large tress.
What is secondary succession ?The life cycle of a plant is characterized by secondary ecological succession. Secondary succession, in contrast to primary succession, is a process initiated by an occurrence such as a forest fire, harvesting, hurricane, etc. that reduces an already established ecosystem (such as a forest or a wheat field to a smaller population of species.
As a result, secondary succession occurs on preexisting soil, whereas primary succession typically takes place in a location lacking soil. Many elements, including trophic interaction, starting composition, and competition, might influence secondary succession. Trade-off with colonization
Therefore, the given communities can be ordered from the small level to higher level as grass, shrubs, small trees and large tress.
