Science based on properties of matter and energy
One way is the spinning of the wheels can be used to charge a battery. Just like with a generator, you can convert the rotational mechanical energy of the wheels spinning into electrical energy due to Faraday’s Law of Induction if there are magnets on the wheels.
These applications DO NOT INVOLVE harmful ionizing energy:
- MRI
- ultrasound
- laser surgery
I think 23 is b and 24 a?
They're similar in the sence that they involve the perception of light, they're different because they're different perceptions of light.
Hope this helped!
