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.

A submarine fills a special storage area known as a ballast with water in order to increase its density. This allows it to dive deeper in the ocean. When a submarine needs to rise rapidly, compressed air is used to push the water out of the ballast. What effect does replacing the water in the ballast with air have on the submarine?
Answers
Answer:
the submarine floats after replacing the water with the compressed air
Answer:
The submarine will rise.
Explanation:
To get a submarine to surface, the main vents in the top of the tank are closed and high-pressure compressed air is blown into the ballast tanks, forcing the water out through the flood ports at the bottom of the tank. This increases the vessel's displacement.

List the communities in a successional sequence of secondary succession?
Answers
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.

In a chemical reaction, which of the following is true of the products?
A. The products have the same shape as the reactants.
B. The products have the same physical properties as the reactants.
C. The products have the same state of matter as the reactants.
D. The products have the same number atoms as the reactants.
Answers
The correct statement about the chemical reaction is "the products have the same number atoms as the reactants."
What is chemical reaction?A chemical reaction occurs when one or more reactants (also known as reactants) are changed into one or more products (also known as products).
Chemical transformation occurs as a result of this process, which involves the breaking and forming of chemical bonds.
Rust is formed when iron and oxygen combines with each other.
Only the atoms present in the reactants can end up in the products of a chemical reaction. There are no new atoms formed, and no atoms destroyed.
In a chemical reaction, the reactants and products have the same atoms, but they are rearranged during the reaction. As a result, the atoms in the products end up in various combinations. As a result, the products are new chemically distinct substances from the reactants.
Hence, the correct statement is option D.

Question 10 options:
Low tide
Spring tide
High tide
Neap tide
Answers
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.”
