Resistance

 ✓ Resistance 

Resistance is the restriction to the flow of electrons 

  SI unit- Ohm Ω 

R=V/I 

-> Size 

More length - More resistance

Less length - Less resistance

-> Thickness 

Thin - More resistance

Thick - Less resistance

-> Material 

Copper - Less resistance

Aluminum - More resistance


-> Temperature

More temperature - More resistance

Less temperature - less resistance

More temperature - More resistance


Less temperature - less resistance

What is cell Theory, What makes plants appear green, what is a vacuole, what are unicellular organisms........ask why

 Q) What Makes plants appear green? Ans- Plants appear green due to the presence of a pigment called chlorophyll. There are high concentrations of chlorohyll in chloroplasts. These plastids are responsible for photosynthesis. Q) What is a vacuole?  Ans- The vacuole is the cell organelle that stores excess. water and gives support and rigidity to a plant cell. It occupies about 80% of the plant cell volume. Q) What is cell theory ? Ans-  The main postulates of cell theory are: • All living organisms are composed of one or more cells.  • Cell is the basic unit of structure, function, and organisation in all organisms. • All cells come from pre-existing, living cells. • All living cells do not have cell walls. It is present only in plants, fungi and bacteria. Q) What are unicellular organisms? Ans-Unicellular organisms are made up of just a single cell. All basic functions that are required to sustain life such as growth, repair and division are all carried out by that ...

Agriculture some important points............BCDP

 1) Brazil is the leading producer of coffee in the world.  2) Rice is the major food crop of the world and it is the staple diet of the tropical and  sub-tropical regions. 3) Growing of vegetables, flowers and fruits for commercial use is known as  Horticulture.  4) Shifting cultivation is also known as ‘slash and burn’ agriculture. 5) Nomadic herding is practiced in the semi-arid and arid regions of Sahara, Central  Asia and some parts of India, like Rajasthan and Jammu and Kashmir. 6) Intensive subsistence agriculture farmer cultivates a small plot of land using  simple tools and more labor.  7) Shifting cultivation is practiced in the thickly forested areas of Amazon basin,  tropical Africa, parts of Southeast Asia and Northeast India.  8) Commercial grain farming is practiced in the areas of temperate grasslands of  North America, Europe, and Asia.  9) Mixed farming is practiced in Europe, eastern USA, Argentina, southeast...

Distance and displacement......... Physics, Laws of motion

Distance  is the path covered by the body Distance is a scalar quantity It is dependent on path followed by object Displacement  is the shortest distance covered by the body It is a vector quantity It is independent on the path followed by the object Displacement is defined as the change in position of an object ∆x = X initial — X final ∆x = Xi — Xf # When final position is equal to the initial position we say displacement is zero Distance ≥ Displacement  Created and edited by Sai Group Sai Group In case of any doubt frankly ask in comments, I will try to answer Viewer's now you can also ask questions and also answer questions, follow Sai Group Happy learning Thank you
