Is a match being lit a physical or chemical change?
A burning match is a chemical change. Burning anything is a chemical change because it forms a new substance. A physical change just alters the shape or appearance of a substance. For example, burning wood turns it into ash, a new substance, so its a chemical change. Cutting a piece of wood in half changes how it looks, but its still the same substance as before, just separated into two pieces. There are three common types of evidence of a chemical change. 1. A change in color due to a reaction with another substance. The match is reacting with fire and oxygen. 2. The production of a gas. the match gives off a smoke. 3. Formation of a precipitate or a solid that forms and saparates from a liquid mixture. burning a match does not form a precipitate, but adding acid to milk causes the proteins in the milk to undergo a chemical change that alters their structure, so they clump together. * A burning match is an example of a chemical reaction in progress. When the matchstick burns, oxygen from the air is used, mainly to form water vapor and carbon dioxide. The smoke that is generated, is a complex mixture of gases and small particles from the matchstick.
What terms are associated with urban geography?
Terms associated with urban geography include gentrification, urbanization, urban sprawl, zoning, and city planning. These concepts are used to study the organization, development, and social dynamics of cities and metropolitan areas.
What is Quantum Phsyics?
Quantum physics is the study of the motion of particles, specifically the study of the behavior of subatomic particles such as photons, quarks, neutrons, leptons and about 20 others. These particles make up the basic atom and are responsible for the interactions of atoms and the basic properties of matter and energy.Quantum physics is the area of physics that focus on things that are on the atomic scale. Quantum physics, or quantum mechanics, explains why atoms, electrons, etc. act the way they do specifically on that really small scale.
What is the syllabus for MSc-2 organic chemistry mumbai university?
msc is not based on sylabus it is only knowing the knowledge of organic chemistry. i think organic chemistry is not a easy work. i read lot of mechanism but still has across a problem. means u know allthing u know nothig that is chemistry.bcz its not like phy math i.e have a surten formule and apply and get u answer. i think chemistry is defiend as i giving a product and find the answer in proper way.bcz molecule is reacted on way that is in not on your choice
What is the rest masses of the fragments unstable particle having a mass of 3.34 10-27 kg is initially at rest The particle decays into 2 fragments that fly off with velocities of 0.987c and -0.868c?
See this link for relatavistic mass: hyperphysics Dot phy-astr Dot gsu Dot edu/hbase/Relativ/tdil.html It is not letting me put the link in as normal, so I put the "dots" in. Remember that momentum is conserved. Since initial momentum is zero (since it is at rest) the net momentum of the two particles must cancel each other to equal zero. They are traveling in opposite directions. Let the rest mass of one particle equal m1, then the rest mass of the other particle is (3.34 x 10^-27 kg) - (m1). Plug those into the relatavistic mass equations, and set the magnitudes of momentums equal. Then you can solve for m1.

Explain whe the acceleration of two free-falling objects having different masses is the same Is the force on each mass the same?
The acceleration of two free-falling objects with different masses is the same because they experience the same gravitational force from the Earth. According to Newton's second law, F = ma, where F is the force, m is the mass, and a is the acceleration. Since the gravitational force is proportional to the mass of the object, the force on each mass is not the same, but the resulting acceleration is.
