Explanation:
Given:
x = 3 m
The spring potential energy is
1. Sedimentary rock
2. Metamorphic rock
4. Igneous rock
Umm I’m not 100% sure because I learned all this back in 5th grade and I can’t really remember. But this is what I think I know.
Also for your 2nd question I don’t really know
Answer:
Here are the em radiation in order of increasing frequency from left to right. Also, the wavelength decreases as we move from left to right.
Radio, micro, infrared, visible, ultraviolet, x-ray and gamma ray.
According to quantum physics, you use E = hf ( where E = energy of a photon of a type of em wave, h is Planck constant and f is frequency of that photon ) to find the energy.
From here you can see that as we move from left to right, energy increases because frequency increases.
