Explanation:
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.
To be a good prince you have to put your people before anything
In this quote, Representative Barbara Jordan of Texas was addressing the <span>1976 Democratic National Convention. She starts by stating how the fact that she is the keynote speaker of the convention serves as evidence for the importance of following one's dreams even when they might seem impossible. She then states that many people fear the future and don't trust their leaders, and just look for personal gain. Then, she states how this poses a danger for the country as it can lead to an extreme segmentation of the country. To support her argument she appeals to fear by portraying a future where everyone is against everyone in the search for their own benefit.
Therefore, your best answer is Appeal to fear.</span>
