Answer:

3) A single specific wavelength

Explanation:

When an electron returns to ground state, it has to emit a single photon.

When a single electron returns to the ground state from an excited state, it emits a single, specific wavelength of light. Therefore, option 3 is correct.

The separation between any two points in a wave and those identical points in the following wave cycle. This can be null-to-null, crest-to-crest, trough-to-trough, etc.

A spectrum is the term used to describe the range of wavelengths or frequencies for wave phenomena. The term was originally used to describe the electromagnetic spectrum, but it is now used to describe the sound spectrum and vibration spectrum.

When electromagnetic radiation such as radio waves, light waves, or infrared waves travel across space, they leave behind distinctive patterns. Each wave has a distinct size and form. Wavelength is the separation between peaks.

Thus, option 3 is correct.

Answer:

True.

Explanation:

In metallic bonds, nuclei of metal atoms line up uniformly and the electrons are delocalized (spread out evenly). Since this allows electrons to move around freely, and electricity is created by the flow of electrons, metals can conduct electricity.

Chemical energy

Explanation:

I hope this helped you!

Batteries store the energy in the form of chemical energy that chemical energy is converted into electrical energy. Chemical energy is used to stored in the substances within battery.

The conversion of chemical energy into electrical energy or vice versa is called as electrochemical energy . This includes reactions transferring electrons, redox reactions .

Redox reaction in which reduction and oxidation takes place simultaneously. Reduction, when a substance receives one electron. Oxidation when a substance gives away one electron.

A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit.

Thus, chemical energy is used to store in the substance within battery.

Answer:

Accuracy of a measured value refers to how close a measurement is to the correct value. The uncertainty in a measurement is an estimate of the amount by which the measurement result may differ from this value. Precision of measured values refers to how close the agreement is between repeated measurements.

Explanation:

Tornadoes form when updrafts from thunderstorms begin to interact with strong wind shear and develop a rotating column of air.

Updrafts are powerful vertical currents of air that occur within thunderstorms, caused by the rapid heating of the Earth's surface and the subsequent convective process. These updrafts carry warm, moist air upward, creating a conducive environment for the formation of severe weather phenomena.

When the updrafts encounter wind shear, which is the change in wind speed and direction with height, it can lead to the development of horizontal vorticity. Wind shear creates a rotating motion within the storm, where air at different heights starts to rotate at different speeds, generating a horizontal spin.

As the updraft continues to intensify, it tilts the rotating column of air from horizontal to vertical, forming a mesocyclone. The mesocyclone is a critical component in tornado formation. It acts as a localized area of strong rotation within the storm, extending from the cloud base to the mid-levels of the atmosphere.

Under specific conditions, such as the presence of a strong updraft, a well-developed mesocyclone, and further enhancement from other atmospheric factors, the mesocyclone can contract and intensify into a tornado. The process is complex and influenced by various meteorological factors, but the interaction between updrafts, wind shear, and the development of rotation plays a fundamental role in tornado formation.

source is where i got this information and the in your own words is it fully rewritten hope this helps and my aplogies for making this so lengthy!

    This is not exactly a answer you can use but this is some information that you can use to find out the answer.

    You can usually confirm the charge associate degree particle unremarkably has by the element's position on the periodic table: The alkali metals (the IA elements) lose one negatron to create a ion with a 1+ charge. The alkaline-earth metal metals (IIA elements) lose 2 electrons to create a 2+ ion.

    Nonmetals type negative ions (anions). A range 7|chemical element|element|gas} atom should gain 3 electrons to possess an equivalent number of electrons as AN atom of the subsequent gas, neon. Thus, a gas atom can type AN ion with 3 additional electrons than protons and a charge of 3−.

The orientation of the poles of the magnet on the cars and the large

magnet are like poles.

The correct responses are;

First question

Second question:

Third question:

Fourth question:

Reasons:

Potential energy is the energy an object has due to its location.

Energy is a product of force and distance, and therefore, if the force,

experienced by the object increase, the potential energy of the object

increases.

The strength of a magnetic field, B, is given by the formula;

[tex]\displaystyle B = \frac{\mu_0 \cdot I}{2 \cdot \pi \cdot d}[/tex]

Where;

B = The magnetic field strength

I = Current

d = The distance from the source of the magnet

μ₀ = The permeability of free space = 4·π × 10⁻⁷ T m/A

Therefore, the strength of the magnet is higher closer to the source.

First question

In a magnet, like poles push each other back, and given that the poles of the magnet adjacent to each other are like poles, to get the largest increase in she should move the cars towards the large magnet.

Second question:

The reason why the movement will result in the largest increase in potential energy is because like polls repel each other and the strength of a magnetic field increases closer to the magnet

Third question:

The magnetic force that will act on the roller coaster car moved towards the large magnet, pushes the car in the opposite direction.

Fourth question:

The green cart should be moved from point D to point C to get the largest potential energy
