What do you see happen when you increase the frequency?
Hi, Im new! But, why is physical and chemical changes are different?
Answer:
Physical and chemical changes are different because one deals with changes to ones shape or form, while chemical is changing one substance to another.
Explanation:
A example of a physical change would be cutting a block of wood into a cube of would, its physical change changes from a block to a cube. A chemical change is changing the substance into another substance so for example, burning that cube of wood in a fire. The fire is burning the wood into ash meaning it's no longer wood but ash.

Energy neither be created or nor be destroyed, it can transfer one form to another form. chemical energy is converted into radiant energy is flashlight.
what is chemical energy?
Chemical energy is the energy of chemical substances that is released when they undergo a chemical reaction and transform into other substances.
Chemical energy is converted into electrical energy. i.e. in flash light usally there is a battery in flashlight, battery is made up of chemicals. chemical are in battery under go redox reaction and it converts chemical into electrical. i.e light is nothing but radiant energy.
In other desk lamp uses electric current supply, solar panel which convert solar energy in to electric energy. Light bulb glows by using electric current.
Thus, the electric energy in radiant energy is flashlight.

The amplitude of a wave is related to the energy of a wave. How could you demonstrate this relationship between energy and wave
Answer:
People holding the slinky supply the energy to make the patterns. To make pattern 1, people have to shake the slinky back and forth at a certain speed. To make pattern 2, the slinky has to be moved back and forth faster (higher frequency). To make pattern 4, the people need to move the slinky back and forth much faster. It is much easier to make pattern 1 than pattern 4 because it takes less energy. This illustrates the relationship between frequency and energy – the higher the frequency, the higher the energy.

One substance dissolves in another substance.
The molecules of one substance break down in the other.
Different samples of a single mixture have different characteristics.
One substance can be separated from another through physical means.
The property of every mixture is that One substance can be separated from another through physical means.
What is a mixture?A mixture is when two or more substances mix with each other without participating in a chemical change. The combining substance does not lose its properties or individuality in a mixture.
In other words, the components of a mixture each keep their original properties.
Since mixtures are chemically combined, they can be easily separated by physical means.
Examples of a mixture are crude oil, air, seawater, and gun powder.

The amplitude of a wave is related to the energy of a wave. Did you see anything on the screen that made you think this or could prove your point? How could you demonstrate this relationship?
Answer:The higher the amplitude, the higher the energy. To summarise, waves carry energy. The amount of energy they carry is related to their frequency and their amplitude. The higher the frequency, the more energy, and the higher the amplitude, the more energy.
Explanation:
The amplitude of a wave is directly related to the energy of a wave.
What is amplitude?Amplitude is the maximum distance covered by a body from the main point in the vibrating mode.
As we know that energy of the wave is directly proportional to the square of the amplitude:
E ∝ (a)²
As the amplitude of wave increases, energy carried by the wave is also increases. Higher energy increases the amplitude of the propagating wave.

Explanation:
sixty percent of all active volcanoes occur at the boundaries between tectonic plates. Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. Some volcanoes, like those that form the Hawaiian Islands, occur in the interior of plates at areas called “hot spots.”

Veronica observes how the force of friction causes an object to slow down. She writes the following observation: When an object moves across a smooth surface, there is less friction created than when an object moves across a rough surface. When the object stops moving, friction is created. Which statement corrects the error(s) in Veronica's observations?
It is not smooth or rough surfaces that affects friction. It is the size of the push.
When an object moves across a rough surface, there is no friction.
When an object moves across a smooth surface, the friction increases.
When an object stops moving, there is no friction.
No surface is completely smooth, friction happens. There is higher friction between rougher surfaces. So, it is the wrong statement that smooth or rough surfaces do not affect friction.
What is friction?The resistance to motion of one object moving in relation to another is known as friction. It is not regarded as a fundamental force like gravity or electromagnetic.The interplay of small bumps on the surfaces of objects as they rub together is thought to be the primary source of friction, though scientists are not entirely certain of this. Particles that stick out above the rest can be found on even the most smooth surfaces. As the objects move, these high points collide and scrape against one another, creating resistance. Friction is brought on by this unwillingness to move.Sliding friction, fluid friction, and rolling friction are the three primary categories into which friction can be categorized. The items that are moving and the force being applied to them determine the type of friction.To learn more about friction, refer to

1. Express the wave speed of each wave described below in meters per second.
A wave travels through a 2 meter rope in 1 second.
Answer:
In this instance, the sound wave travels 340 meters in 1 second, so the speed of the wave is 340 m/s. Remember, when there is a reflection, the wave doubles its distance. In other words, the distance traveled by the sound wave in 1 second is equivalent to the 170 meters down to the canyon wall plus the 170 meters back from the canyon wall.
Explanation:
Among electromagnetic waves, UV rays are most dangerous because exposure to these radiation cause serious problems in living organism. Therefore, in below given ways, speed of each wave can be expressed.
What is electromagnetic wave?Electromagnetic wave is a wave which contain two component one is electric component and other is magnetic component. The electric and magnetic component are perpendicular to each other. There are so many wave that comes under electromagnetic wave like infrared wave , radio wave.
There is a relation between energy of wave. frequency of wave, and wavelength of wave
Mathematically,
E=hc/λ
where,
E = energy of electromagnetic wave
h is planks constant having value 6.67×10⁻³⁴js
c is speed of light that is 3×10⁸m/s
λ is the wavelength of electromagnetic wave
The sound wave moves 340 meters in one second, hence its speed is 340 m/s. In the event of a reflection, the wave's distance doubles. The distance covered by sound wave in one second is comparable to 170 metres down to a canyon wall + 170 meters back.
Therefore, in above given ways, speed of each wave can be expressed.

Explanation:
do you think the reflected waves would ever return to the airplane that transmitted them? explain
The reflected waves should not return back to the transmitted source if there no hindrances in the moving trajectories. If there is any hindrance or objections in front of the reflected wave there may occur some directional change and does not return to the airplane.
What is reflection?Reflection is phenomenon by which an incident wave on an object return backs in the straight direction. Reflection make an object shiny as we see from a mirror.
When light passes through a transparent or translucent material it penetrates through it and will refract or scatter from the object. This will happen when the frequency of the incident light does not matches with the frequency of the incident light.
If the a some waves are transmitted from an airplane and they are reflected in a straight direction, it will not revert back to the airplane because the reflected light will moves in a straight direction back from airplane.
