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.
If you mean how does use of questions contribute to the development of ideas in general, then it makes the raiders think as they read.
Answer: A. She wants to talk to her mom about her worries and is hesitant to approach her.
The poem "Hanging Fire" by Audre Lorde is meant to give us a glimpse into a teenage girl's mind. The author jumps from one thought to the next in a desperate fashion. The thoughts seem unrelated and scrambled, but they are all concerned with topics that would worry a fourteen year old. The style is meant to give us the feeling of confusion and worry that is common among teenagers.
However, at the end of each nervous train of thought, the girl notices her mother is in the bedroom with the door closed. It implies that she would like some help, and she would like to turn to her mother. But there is some slight difficulty, which is the closed door. However, the obstacle is not difficult enough to put her off the idea completely, which is why she keeps noticing it. This ambivalence leaves her in a constant state of hesitation, but she does not approach her mother in the end.
