I know I already asked you this in class, but I don't know if I was clear enough. This is what she said, which made me confused.

ohhh! I see. I was thinking of something else; thank you!

Every charged particle creates an electric field around it. Imagine this like an invisible force field that either pulls things in or pushes them away.

A positive charge (+) creates a field that pushes outward.

A negative charge (-) creates a field that pulls inward.

When you place:

A positive and negative charge near each other, their fields pull them toward each other. → Attraction

Two positive or two negative charges near each other, their fields push them away from each other. → Repulsion

The Energy Argument (Nature Loves Low Energy!)
Everything in nature tends to move toward lower energy.

Opposite charges lower their energy when they come together → so they attract.

Like charges increase their energy when they come together → so they repel.

3.
Think about a magnet:

A north pole and a south pole attract each other.

Two north poles or two south poles push each other away.

This is a bit different from electric charge, but the idea is similar—opposites fit together more naturally!

1. Understanding the Nucleus (Why It's Unsolved?)
We know that protons and neutrons stick together in the nucleus because of the strong nuclear force, but we don't fully understand all the details. Some mysteries include:

Why are some nuclei more stable than others? There are patterns in nuclear stability that we can't fully explain.

Why do some experiments give different results for neutron decay? This could mean there's something we don't understand about how particles behave.

How do nuclear forces really work? The strong force is incredibly complicated, and we can't perfectly predict nuclear interactions.

2. Fusion Energy (Why It's Hard?)
Fusion is what powers the Sun—it's when small atoms combine to make bigger ones, releasing huge amounts of energy. Scientists want to use this for clean energy, but there are big problems:

It takes extreme heat (100 million °C) to start fusion. Keeping that heat inside a reactor is really difficult.

We haven't made it efficient yet. So far, we use more energy to start fusion than we get out.

The reactor materials break down. The extreme conditions wear out the walls of the reactor, so we need materials that can survive.

Scientists are working on both problems, and solving them could change our understanding of physics and energy! 🚀

Hi, I was searching for unsolved problems, and it showed like quantum gravity, etc. It also showed an "understanding of the nucleus" and "fusion energy." What do they mean by this? THow are they "unsolved?"

hi, this is a random question, but I was just wondering: why do opposites attract and likes repel? Like why do they? I think we have discussed this before but I sorta forgot. I searched this up, and it said , " Coulomb's law, which states that the force between two charges is proportional to the product of the charges and inversely proportional to the square of the distance between them". I'm still a bit confused, like I understand that it's about the charges and the forces in between them, but how come? Sorry if this is confusing.

Actually answer is d but we have not done stereoisomers yet in class. So please ignore it.
