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 answer is D. Pertinent comes from the word pertain/pertaining, which means relevant.

Answer:
Female factory workers had to work long hours, sometimes up to eighty hours a week.
Explanation:
Joan Dash provided a poignant and eye-opening historical account of the women's factory strike of 1909 in "We Shall Not Be Moved." This provides an insight into what the condition was like for women and also how the Women's Trade Union League came to be.
In the given passage from the text, the narrator reveals how the women's demand was simple: <em>"a fifty-two-hour week with extra pay for overtime, an end to the fines and petty tyrannies, and a living wage." </em>And in order to understand what the basis of the demands were, we have to know the situation of workers, especially female workers during the early 1990s. And the fact that <u>women workers were expected to work for long hours, at times even up to eighty hours a week</u> was too much for any living being to endure.
Thus, the correct answer is the first option.
