How can a charged balloon attract a wall without any contact?

The positive charges of the uncharged wall move to the outside.
The wall changes shape and the positive charges move to the inside.
The negatively charged balloon repels and moves away from the wall.
A positive charge in the balloon attracts the negative charges in the wall.

Answers

Answer 1

Answer:

Because it is charged with the opposite type of energy to the wall.

Answer 2

Answer: A

Explanation: The positive charges of the uncharged wall move to the outside.

The average speed of the blocks are 0.36 m/s.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed with respect to time. As at time t = 0 , the speed is also zero, and at time t = 2.5 s , the speed will be
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.
The answer is 0.36 m/s credit to the guy above me (give him Brainlyist) but I also had to do this assessment.

Im writing a story and need some ideas on what should happen next. About thirty minutes later, I hear a car horn outside my apartment. This is it. The moment Im going to enter the car of the person Im supposed to hate. Why did I tell him Id go to the park with him? I walk out and try to open the car door, its locked. I knock on the window and mouth to him that the door is locked. He nods his head and starts laughing at me. I knew this was a bad idea. He is awful! I angrily glare at him for a few seconds until he finally unlocks the door and lets me in. When I enter the car I ask him, Why did you do that? He laughs and says, Because it was funny. I roll my eyes and say, No it wasnt. He starts the car then says, Wow, not even thirty seconds with me and youre already rolling your eyes? I glare at him for what feels like forever and he makes another sarcastic comment, Sunflower, if you wanna stare at me, you should take a picture. It lasts longer. Ugh! Youre so annoying, Im so regretting coming with you! He grins and keeps on driving. I honestly still have no idea why he invited me but I guess Ill never know. After minutes of awkward silence, I decide to say something. So pretty boy, why did you invite me to the park? He looks over at me and says, I have a name you know. Yeah, so do I, but yet, you never use it. He smiles at me. True, he says. I smile. Im really getting used to this fun side of him. Hang on, what? What am I saying? Getting used to him? No, never. I get rid of that thought and as I do, he parks the car and says, Here we are. Are you ready to have fun? I look over at him and respond, Im with you, Im not sure how much fun I can actually have. He rolls his eyes and says, Right back at you. Youre no fun either. I ignore him and we get out of the car.What should happen while these two are at the park?
