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

Answers

Answer:

Seat belts are in cars to the effects of inertia. ... When the car hits the wall, you would keep moving in a straight line and at a constant speed until the dashboard applies a force. Seat belts hold you and passengers down, protecting them from their own inertia.

Explanation:

their is the answer so okay

Answer:

Inertia is the tendency of an object to resist a change in velocity.  

When a car stops suddenly, your body is still going at the same speed the car was before it stopped (say 65 MPH). Without the belt strapping you in from behind, you would fly forward at nearly that same speed (65).

But thanks to the seatbelt, it stops your body's inertia.

Alison finds the total mass of a sample of baking soda, a balloon, and a glass container with vinegar in it. She adds the baking soda to the vinegar and immediately places the balloon over the mouth of the container. After the reaction is complete, she again finds the total mass of the system.

Which statement is true:
1. The mass does not change because chemical changes observe the law of conservation of mass.
2. Mass is gained during the reaction because a chemical change is taking place.
3. Mass is lost during the reaction because the gas is less dense than the baking soda or vinegar.
4. Mass is lost during the reaction because the gas can change in volume but baking soda and vinegar cannot.

Greenhouse gases trap thermal energy and reflect the sun’s harmful radiation back to Earth.

Thus, the correct option is D.

What are greenhouse gases?

Greenhouse gases may be defined as those gases that absorb infrared radiations which are competent to trap heat. Some examples of greenhouse gases are carbon dioxide, methane, CFCs, nitrous oxide, etc.

Greenhouse gases are more complex as compared to other gas molecules in the atmosphere. It has a structure that makes such gases more competent to absorb heat and radiate back to the Earth's surface. These gases trap the ultraviolet radiation from the sun and emit toward the earth's surface. Such gases are responsible for greenhouse effect.

Greenhouse gases are harmful to the environment as well as the health of living entities that constantly living in various ecosystems of the environment.
