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.
I am unable to understand the question
Oliver Wendell Holmes's "Contentment" is ironic since it is used to criticize society and politics. Satire is a literary device that uses irony<span> and humor to ridicule the practices of society, politics and people. </span>I hope my answer has come to your help. God bless and have a nice day ahead!
This is false, and the opposite is true!
A want, used as a noun, refers to something that is not necessary, but something that is wanted, desired only.
A need, in contrast, refers to something that is necessary, so it is not merely something that is wanted, but something that is very essential.
I believe the answer would be C, its. Its is used to describe something that's connected to an animal or an inanimate object.
