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.

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

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. :)

I need you to change the wording the best you can 100 pointsTo survive is to continue to live or exist, typically in spite of an accident, ordeal, ordifficult circumstances. To survive, individuals must sometimes change and adapt to theirenvironment. Survival is one of the main themes in the novel A Long Walk to Water by LindaSue Park. The main characters, Nya and Salva, both experience difficult circumstances. In thenovel, Park uses the stories of the two main characters to show the mental, emotional, andphysical challenges that occur when struggling to survive.In the novel, A Long Walk to Water, one of the main characters, Salva, was forced toleave his home due to the Sudanese Civil War. He went on a difficult journey through the deserton his way to a refugee camp. On his journey, he faced challenges such as limited food andwater, hungry lions, and losing people close to him. Despite the many obstacles Salva faced, hekept going. Park writes, Salva would think of his family and his village, and he was somehowable to keep his wounded feet moving forward, one painful step at a time (Park 54). This quoteshows how Salva managed to survive his challenging circumstances and physical pain by stayingpositive and focusing on what was important to him.The other main character, Nya, also had to face struggles while trying to survive inSouthern Sudan. Nya had to walk many hours each day to get water for her and her family. Thewater she collected was not always clean and safe which caused her family members to becomesick. Seeing her sister fighting for her life because of dirty water became an additional emotionalLast Name 1challenge for Nya. Her long and tiring journey to get this water became a part of her dailyroutine, and it became a necessary part of survival. Park writes Nya would now make hersecond trip to the pond. To the pond and back -- to the pond and back -- nearly a full day ofwalking altogether. This was Nyas daily routine seven months of the year. Daily. Every singleday (Park 20). This quote shows how the struggle to survive became a part of Nyas everydaylife. She was forced to adapt her daily routine to make time to collect the water necessary for herand her familys survival.The struggle to survive and adapt to changing circumstances is something that impactsmany people. In the novel, Salva has a close relationship with his uncle. His uncle acts as aleader to Salva and their entire group. He acts as a support system and helps Salva throughdifficult moments. When he eventually passed away this caused Salva great pain, but he waseventually able to become a leader and help others the way his uncle had. I can relate to Salvasexperience of losing his uncle. When I was younger, I had a close relationship with mygrandmother. She acted as a leader and support system for me and my little sister. She was theglue that held our family together. When she passed away, I was devastated. I did not know whatto do, just like Salva. Eventually, after a lot of time, I was able to heal and work on becoming aleader and support system for my little sister just like my grandmother was to me. Salva realizedthat he needed to help others the way his uncle had helped him, and I realized that I needed tolove and support my sister the way my grandmother had done for me.To survive is to make changes and adapt to the environment around you. Salva wasforced to adapt to life without his uncle and to become a leader for his people. Nya was forced toadapt her daily routine to make time for the long walk to get water each day. Even when lifepresents people with challenges, they must continue to live and exist in their changing world.Last Name 1This is something I and many have faced.
