Why do objects in the sky appear to move and change so much?

Answers

Answer:

It depends on the climate and wind speed at the time.

If the climate is hot and no breeze it will move slower.

If it is cold and very windy it will move rapidly.

for scientist

Could it be possible to run at the speed of sound with some future tool

Answers

Maybe in the future but now no. The fastest a human could run, according to most studies is about 36–40mph, and sound in dry air travels at about 760+ mph. That's considerably faster, almost 20 times actually. The reason why we couldn't ever run anywhere close to 760mph is because human muscles can't conract that fast.

Answer:

Scientists have discovered the fastest possible speed of sound. ... the absolute speed limit at which a wave can travel which is the speed of light

A baker, his wife, Emily and her little sister, me CJ. We lived in the bakery where we worked. I am a blonde girl, 13 years old, and is very overprotective of my older sister. Emily also has blond hair, 38 years old, and caring. The baker is different though. He has brown hair, 39 years old, and very stubborn. One day a witch came and told my sister and the baker that they could not have a child which they wanted for a long time now. She told them that if they wanted a child they would have to get her 4 things from the woods. When we went into the woods I lost them and got lost in the woods. After a while they realized they had lost me and went to go look for me hoping I was ok. It was cold, dark, and very dangerous. I was scared. I wanted my sister. I was hoping they would find me soon, but I was wrong. The next day I was still in the woods all alone. I was starving, but then a 18 year old girl came and found me. She had brown hair and brown eyes. She took me to this cabin in the woods of hers and gave me food and I went back in the woods to look for Emily. A little after a wolf came. It was a big black wolf with cold dark eyes. I asked it to not eat me and then it replied I'm not going to eat you. Then I realized I could talk to animals. I asked the wolf Can you help me? I'm trying to find my sister. She starts to track her down. We never found her because it got dark. She took us to her cave and let me sleep there. The next day we went looking again. I knew we were getting closer because I found Emily's necklace. I started yelling her name, but I heard nothing. I thought they would have given up by now and forgotten all about me, but I didn't give up, I kept looking. We stopped for the night. I was the first to get up. I sat and waited for Bella to get up. I sat there remembering all the fun times me and Emily had together hoping she didn't give up on me. Bella got up and started to track her. I found her bracelet I made for her. I knew we were getting closer and closer. I couldn't wait to see Emily. She is the last real family member I have. It was two days later. Me and Bella were looking for Emily. I heard Emilys voice. I ran to it yelling her name. I found her. She told me that she was worried about me and that she thought she would never find me. I was so excited to see her. Tears were pouring down my face. We went to find the rest of the stuff for the witch and went back to her. We gave her the things and they got what they wanted. They had a baby boy and I became an aunt. I was so happy to be home.
