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

Secondary succession occurs in areas where a biological community has already existed but some or all of that community has been removed by small-scale disturbances that did not eliminate all life and nutrients from the environment.

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.

How are seatbelts related to inertia? Write you answer in complete sentences.
I need answer asap!!!

Answers

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.

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

Your answer would be c I’m pretty sure

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.
