Short note of parents as inspires​
REY [17]

Answer:

My role models are my parents. They are my pillars of strength. They are my guide and give me the courage to battle obstacles in life.

My mother, being a working professional, manages all her work perfectly and with efficiency.

My father goes to office, but still does not forget to help me with my studies. They always encourage me in every aspect and motivate me even when I do not succeed.

My mother always smiles, no matter what the circumstances are and that gives me the strength and inspiration to face all problems.

My parents have made me understand what life is about and how to find that little ray of happiness in difficult situations.

What I am today and what I will become in future involves the support and affection of my parents. They have made me disciplined, dedicated and sincere.

A role model does not have to be a famous personality. It can be anyone who makes us believe in ourselves.

My parents fill sweetness in my life. From childhood I have learnt everything from my parents.

Not just parents, I also consider my teachers as role models. Even they guide me and show the path of success.

They have turned me into a fighter in the war of life

A sample of ideal gas at room temperature occupies a volume of 12.0 L at a pressure of 802 torr . If the pressure changes to 401
Blababa [14]

 The new  volume  is  2.4 L

<u><em> calculation</em></u>

The new volume is calculated using Boyle's  law formula

That  is  P₁V₁=P₂V₂

where,

p₁ =  802 torr

V₁ = 12.0 l

P₂ = 4010 torr

V₂=?

make  V₂ the subject of the formula  by diving  both side of equation by P₂

V₂ = P₁V₁/P₂

V₂  is therefore = {(12.0 l × 802 torr) 4010 torr}  = 2.4 L
