A balloon clings to a wall after it is negatively charged by rubbing because the wall is positively charged.
<h3>Is opposite charge attract each other?</h3>
Yes, opposite charges attract each other. When a positive charge and a negative charge interact with each other, their forces act from the direction of positive to the direction of negative charge. As a result opposite charges attract each other while on the other hand, similar charges repel each other because their forces move in the opposite direction so they repel each other.
So we can conclude that a balloon clings to a wall after it is negatively charged by rubbing because the wall is positively charged.

No it shouldn't, a hypothesis doesn't need to be correct but must have an idea for why x variable effects y variable and have good reasoning. In the conclusion you should state if it's correct or not and explain why it's correct/incorrect and what answer you've determined from data.
The index of refraction
Hold up let me tell you why!!!
The index of refraction which is also known as refractive index is defined as speed of light in a vacuum divided by the speed of light in a giver material.
The formula for index of refraction is:
(n = c ÷ v)
This is where n represents index of refraction
C which represents of light in a vacuum
And V represents speed of light in a given material.
So the speed and the direction of light changes when it moves from one medium to another. And the change direction is basically called refraction......
Hope this is correct and helps you a whole lot!!!
The answer would be B: The ground exerts an equal force on the golf ball.
