pls hurry its a exam!

Answers

Answer 1

Answer:

I think it would take 220, 230 million earth years to match a cosmic year.

Answer 2
It would be 230 million years because of the duration of time required for the Sun to orbit once around the center of the Milky Way Galaxy.

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??

Answers

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

Describe all the ways that Newton’s Laws can apply in the game of football (Remember to talk about ALL THREE LAWS).

no links please ! :(

Answers

first law: an o-lineman standing on the line of scrimmage gets tackled to the ground
second law: a wide receiver sprinting down the line to catch a hail mary pass
third law: a d-lineman and o-lineman pushing each other back and forth (for o) to keep the d-lineman away from his quarterback
When the QB puts forward force on the ball and then lets go, the ball wants to keep moving forward. The more force he puts on the ball the more inertia it will have. And the more mass the football has the more force has to be put on it. :)

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.

THE POPULATION OF NEW YORK STATE CAN BE MODELED BY: Directions: As you read, highlight important passages.Annotate each chunk (main idea, agree/disagree, or connection)Answer questions on page 2House on Mango Street by Sandra CisnerosWe didn't always live on Mango Street. Before that we lived on Loomis on the third floor, and before that we lived on Keeler. Before Keeler it was Paulina, and before that I can't remember. But what I remember most is moving a lot. Each time it seemed there'd be one more of us. By the time we got to Mango Street we were sixMama, Papa, Carlos, Kiki, my sister Nenny and me.Chunk 1 annotation: The house on Mango Street is ours, and we don't have to pay rent to anybody, or share the yard with the people downstairs, or be careful not to make too much noise, and there isn't a landlord banging on the ceiling with a broom. But even so, it's not the house we'd thought we'd get.Chunk 2 annotationWe had to leave the flat on Loom is quick. The water pipes broke and the landlord wouldn't fix them because the house was too old. We had to leave fast. We were using the washroom next door and carrying water over in empty milk gallons. That's why Mama and Papa looked for a house, and that's why we moved into the house on Mango Street, far away, on the other side of town.Chunk 3 annotationThey always told us that one day we would move into a house, a real house that would be ours forever so we wouldn't have to move each year. And our house would have running water and pipes that worked. And inside it would have real stairs, not hallway stairs, but stairs inside like the houses on TV. And we'd have a basement and at least three washrooms so when we took a bath we wouldn't have to tell everybody. Our house would be white with trees around it, a great big yard and grass growing without a fence. This was the house Papa talked about when he held a lottery ticket and this was the house Mama dreamed up in the stories she told us before we went to bed.Chunk 4 annotationBut the house on Mango Street is not the way they told it at all. It's small and red with tight steps in front and windows so small you'd think they were holding their breath. Bricks are crumbling in places, and the front door is so swollen you have to push hard to get in. There is no front yard, only four little elms the city planted by the curb. Outback is a small garage for the car we don't own yet and a small yard that looks smaller between the two buildings on either side. There are stairs in our house, but they're ordinary hallway stairs, and the house has only one washroom. Everybody has to share a bedroomMama and Papa, Carlos and Kiki, me and Nenny.Chunk 5 annotation Once when we were living on Loomis, a nun from my school passed by and saw me playing out front.The laundromat downstairs had been boarded up because it had been robbed two days before and the owner had painted on the wood YES WE'RE OPEN so as not to lose business.Where do you live? she asked.There, I said pointing up to the third floor.You live there? There. I had to look to where she pointedthe third floor, the paint peeling, wooden bars Papa had nailed on the windows so we wouldn't fall out. You live there? The way she said it made me feel like nothing. There. I lived there. I nodded.I knew then I had to have a house. A real house. One I could point to. But this isn't it. The house on Mango Street isn't it. For the time being, Mama says. Temporary, says Papa.
