Hey everyone, I'm Ash!

I'm currently in year 11 in Australia and I do chemistry and physics.

Just a warning that I'm not so great with biology :3

i need help with a few question

Joaquin's bicycle has a headlight that requires no batteries. If he pedals slowly, the light flickers. If he pedals quickly, the light gives off a steady, bright light. How does the headlight get its energy?
A. There are a few magnets attached to Joaquin's front tire, and the light is attached to a coil of wire.
B. Joaquin's wheel acts like a wire coil, and there is a magnet attached to the headlight.
C. There are a few electric charges attached to Joaquin's front tire, and the light is attached to a magnet.
D. There are a few electric charges attached to Joaquin's front tire, and the light is attached to a coil of wire.

@onedirection1213 hmm I'll admit I'm not 100% sure about this question. I looked it up to get some background information, and found this example of a product that seems to do a similar thing. How that works is the bicycle wheels create a magnetic field which is then passed on. Due to that, I would think A is the correct answer, but there is definitely the possibility that I'm wrong :')
