Answer:
Adding enough thermal energy to a substance can cause a change of state to occur. The change of state from a solid to a liquid is called melting. When energy is added to an ice cube, the ice particles speed up as energy is absorbed. When the particles move fast enough, the solid ice melts and becomes liquid water
<span>Question: Organic chemistry is the study of compounds containing?
Answer: (A) Carbon
Organic chemistry is the study of compounds that contain the element carbon, or the study of carbon-containing molecules and the compounds they form. An entire branch of chemistry (carbon chemistry) is dedicated to this subject. Which means carbon is quite important, after all it is the central element to all living organisms. It is the basis to all life on earth. By studying carbon and Organic compounds together scientists can learn more about life, the human body, and how it works!</span>
E = hf
c = speed of electromagnetic wave, c ≈ 3 * 10⁸ m/s,
Planck's constant h = 6.63 *10⁻³⁴ Js
h = Planck's constnat, Frquency, f = c/λ = (3*10⁸)/(488*10⁻⁹)
E = hf
E = hc/λ
E = (6.63 * 10⁻³⁴ * 3 * 10⁸) /(488 * 10⁻⁹)
Energy, E ≈ 4.0758 * 10⁻¹⁹ Joules.
Answer:
Because all the planets orbit the sun in the same direction, along a circular flattened disk.
