Using information about natural laws, explain why some car crashes produce minor injuries and others produce catastrophic injuries.

Answers

Answer 1

Answer: The larger the mass and the speed, the larger the force it would produce if it crashes something. Some car crashes produce minor injuries because maybe this car is small and runs at very slow speed which would mean less force when in impact with another. However, if a big truck crashes, it is expected to produce a larger force causing catastrophic injuries.

Answer 2

Answer:

The car crash in which the car is moving at higher speed will cause catastrophic injuries whereas the car moving at smaller speed will cause minor injuries. This is due to the law of inertia of the bodies.

Explanation:

The inertia of a body is defined as the resistance of the body towards any change in its current state of rest or motion. The body does not want to change its state and this resistance of the body is directly proportional to the mass of the body.

According to the law of inertia, a body continues to be in its state of rest or motion until and unless an external force acts on the body.

A car moving at a higher speed and having a higher mass is considered to have higher inertia of motion and therefore when it crashes, it experiences a very high stopping force and due to this, the injuries caused in the car crash will be very catastrophic.

Whereas, if the same car is moving at a lower speed, the inertia of motion of the car will be less and when this car crashes, it will experience a smaller force and comes to rest. Due to this, the injuries caused in the crash will be minor.

Thus, The car crash in which the car is moving at higher speed will cause catastrophic injuries whereas the car moving at smaller speed will cause minor injuries. This is due to the law of inertia of the bodies.

Answers

What is not the ultimate goal of science is to produce unchanging and absolute answers - D. Scientists would like to, however, understand patterns, give explanations for natural events, and even make predictions. And it isn't really the case that they would like to produce unchanging answers.

Which of the following does not contribute to Wellness

Answers

The option that does not contribute to wellness are tendencies. Tendencies are just things that you are more likely to do, or behavior that you are more likely to show, and in no way does that affect your wellness.

Nuclear fusion occurs in stars.
a. True
b. False

Answers

Answer : The given statement is True.

Explanation -

Nuclear fusion is a thermonuclear reaction in which light stable nuclei combine with each other in order to form a heavy stable nucleus with the release of large amount of energy.

In case of stars, four hydrogen nuclei combine with each other to form a helium nucleus with a release of 26 Mev per cycle.

Thus, nuclear fusion occurs in stars is true statement.

Stars are powered by nuclear fusion in their cores, mostly converting hydrogen into helium. The production of new elements via nuclear reactions is called nucleosynthesis. A star's mass determines what other type of nucleosynthesis occurs in its core (or during explosive changes in its life cycle). READ THIS AND YOU WILL UNDERSTAND I THINK IS TRUE

Which of the following is a possible use for nuclear energy?a. power plants
b. weapons
c. powering submarines
d. all of the above

Answers

Nuclear energy can be used to power all ofthe above choices. Nuclear power plants produce radioactive waste that must bestored properly. It is very impossible for a nuclear power plant to have nowaste at all since lots of chemicals are used to create the process as it givesenergy to other machines, weapons such as bombs and powering submarines. Radioactive waste can not be released intolocal water supplies since the wastes are very radioactive and may causemutation to the fishes and bioaccumulation which will affect humans as well. Itwill also cause air pollution if the chemicals are not stored properly.

D. All of the above. you're welcome
