What is true about the inertia of two cars, Car A of mass 1,500 kilograms and Car B of mass 2,000 kilograms

Answers

Answer 1

Answer:

Answer:

Car B

Explanation:

Inertia of a body is the property to oppose its state of rest or state of uniform motion. It is also equivalent to the measure of its mass. Newton's first law of motion is also called as law of inertia.

According to given question, we have to write the name of car having more inertia. So, the body having more mass will have more inertia.

The mass of car A is 1500 kg while the mass of car b is 2000 kg. Hence, car B will have more inertia.

Answer 2

Answer: Car B has more inertia then Car A

How do charges move through an insulated wire connected across a battery? Use the terms potential difference, current, conductor, and insulator in answer.

Answers

The battery has both a positive side and a negative side. The potential difference will be the potential of the positive end of the battery minus the potential of the negative end, which will result in positive potential, or power. This potential is what gives the electrons the ability to flow from the positive end to the negative end, or to make a current. While the outside of the insulated wire is the insulator, the inside of the wire has copper, which is the conductor of the current. So, this current will go through the copper of the wire (and not the insulator) from the positive side to the negative.

Answer:

Battery is the source of electrical energy which will help the charge to flow through a medium.

Battery is a constant source of potential difference which will create constant potential difference across the ends of a conductor where it is connected.

When a charge is passed through the constant potential difference then the change in electrostatic potential energy will give kinetic energy to the charge.

It is given as

$q\Delta V = (1)/(2)mv^2$

so here charge will continuously flow through the conductor across which potential difference is applied by the battery. This constant motion or flow of charge is known as electric current.

What part of a standing sound wave does a musician seek in playing a musical note of a specific pitch?

Answers

The correct answer to the question above is that the magician is seeking the wavelength of the standing wave. The part of a standing sound wave, which is its wavelength, the magician is seeking when playing a musical note of a specific pitch.

That is false. I just took the test and it is not the wavelength. The correct answer is antinode NOT wavelength.

How are galaxies created

Hi There! :)

How are galaxies created

Instead of large gas clouds collapsing to form a galaxy in which the gas breaks up into smaller clouds, it is proposed that matter started out in these “smaller” clumps (mass on the order of globular clusters), and then many of these clumps merged to form galaxies, which then were drawn by gravitation to form galaxy ...

Hi!Galaxies are thought to begin as small clouds of stars and dust swirling through space. As other clouds get close, gravity sends these objects careening into one another and knits them into larger spinning packs.

What parts of an atom can change during a nuclear reaction that cannot change during a chemical reaction? Question 15 options: A. The number of protons and neutrons B. The number of electrons only C. The number of protons and electrons D. The number of neutrons and electrons

Answers

Answer;

B. the number of protons and neutrons

Explanation;

Nuclear reactions involve a change in the nucleus of an atom, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei.
Therefore the parts of an atom that can change during a nuclear reaction but can not change during a chemical reaction is the number of protons and neutrons that are found in the nucleus.

Neutrons and protons cannot be removed from nucleus from chemical reactions because they are strongly held together but nuclear reactions are strong enough to separate them. Hence option A is correct.

What measures the distance between two consecutive crests of a wave?

Answers

The distance between two successive crests or two successive troughs is the wavelength for a transverse wave. The height of the crest from the undisturbed water position or the depth of the trough from the undisturbed water position is the amplitude of the wave.

Why were behaviorists unlikely to view cognition as a part of learning?

Answers

Behaviorists are unlikely to perceive cognition as part of learning because they believed that learners respond to stimulus. It is the negative and the positive reinforcement that the learners receive that shape their behaviors or responses to certain stimuli and not cognition.

Answer:

Cognition is unobservable.
