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.
The topic sentence of paragraph 7 of the passage is That was in 1998, and by 2013, around 70,000 volunteers had removed more than 7.5 million pounds of garbage from along the Mississippi and other rivers in several states.
<h3>What do you understand by Topic sentence?</h3>
A topic sentence is a sentence that sums up the fundamental thought of a passage.
It is generally the main sentence in a passage. Otherwise called the fundamental thought what the author's situation on that theme, it exemplifies or sorts out a whole passage.
A theme sentence, generally the principal sentence in a section, presents the primary thought of that passage and establishes its vibe.
A theme sentence is particularly significant in articles, where points change from one passage to another. This makes knowing how to compose a subject sentence vital for any understudy or author.

The lines which are a flashback here are: She thought of her last day in middle school, seven years ago, when Sarah had given her an iPod. She had felt ecstatic that day when she realized she would be able to listen to her favorite songs and fend off comments from her cousins about how little she knew about music.
<u>Answer</u>:
The mood of the story "The Ransom of Red Chief” is fun and light.
<u>Explanation</u>:
"The Ransom of Red Chief" by O. Henry is a light, fun and comical story. Though the story is on kidnapping and taking the ransom for a young boy “Johnny Dorset”, but the mood in the story is light. This is because Bill and Sam, the kidnappers are dumb and idiots. Johnny is the devil’s child, he makes the life of kidnappers very miserable. This leads to comic ways in the story.
Funniest part is when Johnny’s mother, Ebenezer Dorset agrees to take her son back only if Bill and Sam pay her.
