Physics, Chemistry and Biology: Post your doubts here!

do our answers get checked fully if we have exceeded the number of lines given on the question paper?

Yup , it still is checked .

question 16

Evn I posted the same doubt.. But I just checked the ER... And it says we are expectd to understand that the section is through ventricles and the left side has thicker walls than the right side.. That kinda fits and so the ans shud be A... U may check the ER urself..!!!

What is the color of the iron metal deposited in a displacement reaction? (e.g iron displaced in a reaction between iron sulfate and zinc)

 

[smart_boy]

After displacement , Iron ( Fe ) is left as a precipitate... Red/Brown colour.

Iron is a transition metal..!!! Iron3 hydroxide is red-brown.. The metal itself would be silvery-white..

Yup ...

What is inertia? Pls explain. Notes will be good.

 

[smart_boy]

What is inertia? Pls explain. Notes will be good.

The scientist Isaac Newton made a law that any object either stays stationary or at constant speed in one direction when zero resultant force is acting on it, unless an unbalanced force acts on it... This is called Newton's First Law of Motion and the tendency or property of an object to follow this law is called inertia... hope u understand what i mean to say...

 

[Afzal1]

Inertia is the tendency of the body the remain at rest or at constant motion unless an unbalanced force acts upon it. this is the Law of Interia.
1)Considering an object at rest, a body tends to stay at rest unless an unbalanced force causes it to move
2) An object when at motion, moves at a constant speed unless an unbalanced force acts upon it to stop

Thanks a lot dude!! But, its inertia not interia

Afzal do you have the marking scheme for chemistry papers if so then post it on the group
