Plz help The momentum of a baseball changes dramatically when struck by a bat.Momentum of the ball is not conserved. The best ex
Luda [366]

Answer:

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.

The movement of Earth's lithosphere is caused by convection within the ___ layer of the earth.
Elena-2011 [213]

Answer:

Mantle layer

Explanation:

The convection of the mantle layer is when energy in the form of heat is transferred from the interior of the earth to the top of the planet, creating convection currents.

This convection in the mantle causes movements in the earth's tectonic plates, which are found in the lithosphere, so the <u>movement of Eath's lithosphere is caused by convection within the mantle layer on the earth</u>. This plate movements can cause earthquakes or volcanic eruptions.
