Explanation:
if you dig a hole through the earth, from one hemisphere to the other, and drop a tennis ball into it, would it get stuck at the center, since thats where gravity's at, or would it pop up out the other side??
Answer:
Depending on which hemisphere it is, like western to eastern, It would most likely get stuck at the center. You would also have to put more things into thought like acceleration, velocity, and speed.
BUT since the question asked "would it pop out the other side?", I'm assuming it's talking about northern to southern hemisphere. so in that case it would pop out the other side since gravity makes things go downwards.
Answer:
We drop a tennis ball into the hole. The stone is pulled down towards the center of the earth. It falls all the way to the middle of the earth once it reaches the middle, theres no more pull of gravity. ... It would go up a ways, then (due to the pull of gravity) fall back in the other direction, back towards the center
Draw a diagram that shows how Mark and Gina can model the positions of the Sun, Earth, and the Moon, and their orbital paths, during a solar eclipse. You must use all of the tools in your design: lamp, tennis ball, golf ball, and yarn.

Place a lamp 25cm from the model. Move the Moon in front of Earth (right) to see the lunar umbral and penumbral shadow, simulating a solar eclipse. Move it behind Earth (left) to see Earth's umbral and penumbral shadow cast on the Moon, a lunar eclipse.
Which alignment of the sun Moon and Earth causes a lunar eclipse?Image result for Draw a diagram that shows how Mark and Gina can model the positions of the Sun, Earth, and the Moon, and their orbital paths, during a solar eclipse. You must use all of the tools in your design: lamp, tennis ball, golf ball, and yarn.
When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When Earth passes directly between Sun and Moon, its shadow creates a lunar eclipse. Lunar eclipses can happen only when the Moon is opposite the Sun in the sky, a monthly occurrence we know as a full Moon.
