Q1:
In order to find the total momentum of the system, we first consider the initial stage when the can is at rest. The angular momentum of the water and the can is 0.
When the can starts moving, the water in the can also starts escaping. Therefore we can say that the momentum of escaping water and momentum of moving can cancel each other out.
Hence the net momentum or total momentum of the system is equal to 0.
Q4:
Examples of Newton's third law:
1. When a player kicks a football, it moves in the forward direction which is considered as the action. At the same time, the ball pushes back the toe which is considered as a reaction. Both forces are equal in magnitude put opposite in the direction.
2. The Earth's gravitational force is a huge example of Newtons third law. Consider a case of chandelier hanging from the roof. The Earth's gravitational force pulls the chandelier down which is an action. whereas, the same time, the tension in the string attached to roof also pulls the chandelier with equal amount of energy. This is the reaction force.
3. Consider another case of water shooting out of a fire hose. The water moves out of the hose in one direction, which is the action. The force with which the waters moves out pf the hose, pushes the hose in backward direction which is the reaction. In all the examples you can observes that both action and reaction forces are acting in opposite direction but are equal in magniture.
The second one where it starts with Math class
Answer and Explanation:
I was only twelve. The gymnasium seemed so big, but this time it did not intimidate me. This one as well as others had intimidated me for weeks, but now I had conquered them. It had been my very first time competing in a volleyball tournament for my school, and we had won. All the nervousness and anxiety, all that yelling from the coach and teammates had been worth it. We lined up, side by side, facing the seats. My mother and younger brother were there, smiling, happy to see me happy. My mother had made a point of driving me to every single game and watching them to the very end. Somehow, it felt as if the medal I was about to receive was hers as much as it was mine.
All of a sudden, her presence was made even more important. Someone had the idea of inviting the parents onto the court to place the medals around our eager necks. No one else’s parents were there; at least for my team. I was sorry for them, but there she came. She was now everyone’s mother, giving each of my teammates their respective medals and a congratulatory hug. We were all her children for a moment, and sharing my mother had never made me happier.
