Hi, Im new! But, why is physical and chemical changes are different?
Answers
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.

A cube has a mass of 9 grams and each side is 3 cm3. What is the density of the sample?
a.0.33 g/mL
b.36g/mL
c.3g/mLd.18g/mL
Im begging someone to help, Ill mark brainlist!!!
Answers
Answer:
a. 0.33 g/mL
Explanation:
We already know what the mass is (9 grams) so we have to find the volume of the cube next.
Volume = lwh
=(3)(3(3)
= 27
To find density, you have to find mass/volume
density = mass /volume
density = 9 g /27 mL (cm 3 and mL are basically the same thing)
= 0.33 g/mL

Whats the effect of this?
A wave enters a medium where its wave speed is slower.
Answers
Answer:
Wave speed, frequency and wavelength in refraction
Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.
Explanation:
havvee advvanncceed
Answer:
Waves. Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. Light is refracted when it crosses the interface from air into glass in which it moves more slowly.

Answers
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.

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.
Answers
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.

The chemical formula for hydrogen peroxide is H2O2. What is the total number of atoms in 1 molecule of hydrogen peroxide?
Answers
Answer:
THE TOTAL NUMBER OF ATOMS IN 1 MOLECULE OF HYDROGEN PEROXIDE ARE 4 ATOMS.Explanation: 1 molecule of hydrogen peroxide contains 2 hydrogen atoms and 2 oxygen atoms.I HOPE THAT THIS ANSWER HELPS YOUThe chemical formula for hydrogen peroxide is H₂O₂. The total number of atoms in 1 molecule of hydrogen peroxide is four atoms. Two atoms of hydrogen and two atoms of oxygen.
What is hydrogen peroxide ?Chemically, hydrogen peroxide has the formula H₂O₂. It is a somewhat more viscous liquid than water, and very pale blue when it is pure. For consumer use, it is typically diluted in water and used as an oxidant, bleaching agent, and antiseptic. For industrial use, larger concentrations are utilized.
Hair bleaching, surface cleaning, and tool disinfection are all done using hydrogen peroxide. It is also utilized in gardening and dental hygiene.
Two hydrogen and two oxygen atoms make up one molecule of H₂O₂. Therefore, two molecules of H2O2 contain four hydrogen and four oxygen atoms each. Two hydrogen atoms and one oxygen atom make up a water molecule.
Thus, The total number of atoms in 1 molecule of hydrogen peroxide is four atoms.
