force and pressure -post 7

"Always Question, Always Wonder" 

Dear Learners,
Thank you for logging in! You're wonderful!😊 

 At the end of this class, you will be able to:
1. Define Fluids.
2. Explain Pressure exerted by liquids through various activities.
3. State and explain Pascal's Law.

Happy Learning!😊


Pressure exerted by Fluids:

Fluid: Gasses and liquids are collectively called as fluids.

Pressure exerted by Liquids:


A liquid contained in a vessel exerts pressure on its wall and bottom.

1. Pressure due to liquid increases with depth from the surface of the liquid.

lesson -cell structure n function ( POST 2)

Image
Good morning boys! In the last class we learnt that- . Cell is the basic structural and functional unit of life. .Depending on the number of cells , organisms can be grouped as unicellular or multicellular. . The size of a cell is related to its functions. LEARNING OUT COMES- By the end of this class you will be able to- .name the three basic parts of a cell and state their functions .distinguish between a eukaryotic and prokaryotic cell Today we are going to learn about CELL STRUCTURE .a A typical cell consists of three basic parts : 1 .  CELL MEMBRANE OR PLASMA MEMBRANE - . It forms the outer boundary of the cell, gives shape and size  to the cell. . It only allows certain selected substances to enter or leave the cell ( it is semi-permeable ). . It separates the cells from one another  and also from the surrounding medium. NOTE - In PLANT CELLS and BACTERIA there is an outer wall surrounding the cell membrane ,it is called the CELL WALL. It gives protection again

LIGHT-POST 2

Dear Learners, BOYS, WE HAVE A GOOGLE MEET FROM 9am -9.20 am, PLEASE ATTEND IT(THE MEET ID HAS BEEN POSTED ON YOUR CLASS GROUP). AFTER 9.20 ,READ THE BLOG. In the previous blog, we have learned about light and reflection of light. Let me help you to recall few important points 1. Light is a form of energy that enable us to see. 2. There are two laws of reflections.  Today, we will be learning about regular and irregular reflection, real and virtual images. Happy Learning!😊 At the end of it, you will be able to: 1. Differentiate between regular and irregular reflection. 2. Differentiate between real and virtual image. so, lets start the chapter......... When a ray of light falls on a reflecting surface, it get reflected. the amount and the direction of the light reflected depends on the nature of the surface. Depending upon the nature of the reflecting surface, there are two types of reflections. Click the link:  https://www.youtube.com/watch?v=f0NtpGe
