Thanks in advance!

What causes the change in the axial tilt of the earth? Why does it change?

Well I think I have to agree.

Here's my second try. Thanks for your replies ! I assume the tennis ball would be the earth, and the lit globe would be the sun. Only half the tennis ball would be illuminated. (I guess)

http://solar-center.stanford.edu/SID/activities/ionosphere.html Here is my source guys. I forgot to mention "at any time". Why is it half not any other value ?

What is the reason for this? Is it because of the Earth's rotation?

Electrons. But we take the convention of moving "positive charges"

Homework Statement In which direction would the electric field in the wire point if the wire were pulled to the right? Homework Equations Right hand rule F=qvXB The Attempt at a Solution My answer is downward. I am confused whether I should take the moving charges as positive or negative...

Thank You very much! I'll be doing more research on the topic in the next few days.

Thank you ! I will. I will.

I am a 16 year old trying to make a research paper about it for my science high school. I'd like to study how it works and whether it can be applicable to Busan, South Korea. Thank you :)

It is much safer than a normal barrage or dam and is more efficient. Also the way they produce energy.

I was thinking of studying "Dynamic Tidal Power". I am currently reading papers about it right now. I don't really have a strong background in how these sorts of machines work but I am willing to try. Do you think this is a good topic for a novice?

I am having trouble creating new ideas for a physics research paper. My group has three members and we are all interested in generators that run on renewable energy. Unfortunately, we haven't found a topic yet, and the deadline is looming. We don't have a research adviser as well because to get...

Yes thank you very much I found the answer now. I got 0.42 m. Thank! For number four can I use a kinematics formula as well?
