Newton first law of motion
Explanation:
This law by Newton states that an object will remain at rest, or a moving object will stay in motion in a straight line and with the same speed unless an external and unbalanced force acts on the object.
One application of this Newtonian law is in the launching of projectiles like ballistic missiles. A ballistic missile parabolic path is affected by its inertia and the unbalanced forces acting on the object such as air resistance/ drag and gravity.
Answer:
A. Cu^+2(aq)cathode ---> Cu^+2(aq)anode
Explanation:
Electrolysis is the process in which current is passed through a solution thereby causing a chemical change at the anode and cathode. Copper is being purified using electrolysis by using impure copper at the anode and pure copper at the cathode. This pure and impure copper are placed in a copper(ii)sulfate electrolyte solution and dc current is made to pass through it. The resulting changes at the anode and cathode are given by the equation:
cathode: Cu²⁺ + 2e⁻ ⇒ Cu
anode: Cu ⇒ Cu²⁺ + 2e⁻
Answer:
d = Hydrogen and oxygen are being formed.
Explanation:
When current is passed through the water electrolysis take place.
Water is splitted into hydrogen and oxygen gas. Because of this formation bubbles are formed.
At cathode:
2H₂O + 2e⁻ → H₂ + 2OH⁻
Cathode is negatively charged and reduction take place on it.
At anode:
4OH⁻ → O₂ + 2H₂O + 4e⁻
Anode is positively charged and oxidation take place on it.
The over all reaction can be written as:
Chemical equation:
2H₂O (electricity) → 2H₂ + O₂
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
Considering you should look and not touch in museums... A.
