When the bat hits the ball, it exerts some force on the ball. Just think about a home run hitter hitting a stationary ball. How far do you think it will go? Will it go more than 400 ft.? Probably not. While the kinetic energy transferred from the bat to the ball accounts for some energy of the ball, it does not account for all. Where is the mysterious energy coming from?
The answer is conservation of momentum.
I just said momentum is conserved but how do I know that? I know that because of Newton's 2nd law: F=ma (Force equals mass times acceleration)
Conservation of momentum means that the harder you throw you, the harder the ball will bounce back at you. That is the reason it is easier to hit a home run on a fast ball than a curveball.
Conservation of momentum also means that the bat can transfer some of its momentum to the ball. This is why it is better to use a heavier bat if you swing just as fast. The momentum is the product of the mass and velocity, so to make it easier to understand; a heavier bat swung at the same speed as a lighter bat will have more momentum.
1 Chaos and Anarchy
2The government created laws
It means that one government controls the whole population of people and the only way they can do that is to be voted in. The best characteristics of a democraitc is that the rules for the country are directly elected by the people. which means it is the government for the people by the people.
4 a form of democracy in which people vote on policy initiatives directly. Representative democracy is a type of democracy founded on the principle of elected officials representing a group of people, as opposed to direct democracy.
not sure if this helps but next time be sure to not have the questions not so close together. it was kinda confusing.
Answer:
Oranges, these are the main source for vitamin c
Answer:
Middle-class women were in a private circle. They stayed home, took care of kids, and did house chores. On the other side, middle-class men were in the public circle. They went outside from home and do work in the industry.
Explanation:
Men and women grew up in different worlds. Middle-class women stayed home and take care of their kids, prepare meals, clean the house, and do all the other house chores while middle-class men go outside the home and do work in the world of industry, politics, and commerce.
