1.you might have tried the game 'How steady is your hand?' suggested in Chapter 12 of Class VI. If not, you may try it out now. Paheli and Boojho had also set up the game by connecting an electric circuit as suggested in Class VI. They had lots of fun trying it out with their families and friends. They enjoyed it so much that they decided to suggest it to a cousin of theirs who stayed in a different town. So, Paheli made a neat drawing showing how the various electric components were to be connected.
2.Example- BaseNaOH+AcidHCl⟶SaltNaCl+WaterH2O proved
(a.) Machines have led to unemployment.
(b.) They have polluted water and atmosphere. ...
(c) Factories have led to slums where human beings live in squalor.
(d). Our moral and spiritual progress has failed to keep pace with our scientific progress.
(e). We have allowed science to master us instead of using it as our servant.
4. The most basic unit is the cell; groups of similar cells form tissues; groups of different tissues make up organs; groups of organs form organ systems; cells, tissues, organs, and organ systems combine to form a multicellular organism.
5. IF we move torch rigth ,left,upper or down our shadow is also moving like if we take torch near so shadow will become in big size if I take torch far away so our shadow will be shorter
6. if we put magnetic bar to magnet so magnet will not work because magnetic bar has direction of South poal and magnet are the direction of North pole .
7.The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests the Solar System is formed from gas and dust orbiting the SunAnswer :-
→ Current in 10 Ω resistor = 4 A
→ Current in 20 Ω resistor = 2 A
→ Power of the 10 Ω resistor = 160 W
→ Power of the 20 Ω resistor = 80 W
Explanation :-
We have :-
→ 1st resistance (R₁) = 10 Ω
→ 2nd resistance (R₂) = 20 Ω
→ Total current (I) = 6 A
______________________________
The current in the 10 Ω resistor is :-
I₁ = (R₂/R₁ + R₂) × I
⇒ I₁ = (20/10 + 20) × 6
⇒ I₁ = 20/30 × 6
⇒ I₁ = 4 A
The current in the 20 Ω resistor :-
I₂ = (R₁/R₁ + R₂) × I
⇒ I₂ = (10/10 + 20) × 6
⇒ I₂ = 10/30 × 6
⇒ I₂ = 2 A
______________________________
Power of 10 Ω resistor :-
P₁ = I²₁ × R₁
⇒ P₁ = (4)² × 10
⇒ P₁ = 16 × 10
⇒ P₁ = 160 W
Power of 20 Ω resistor :-
P₂ = I²₂ × R₂
⇒ P₂ = (2)² × 20
⇒ P₂ = 4 × 20
⇒ P₂ = 80 W
