Answer:
Emission spectrum
Explanation:
The emmison spectrum is unique to every elements
Light consists of electromagnetic radiation of different wavelengths. Therefore, when the elements or their compounds are heated either on a flame or by an electric arc they emit energy in the form of light.
The color band indicate the amount of energy emitted in form of electromagnetic radiation.
When electrons in an atom gain energy, the become excited, on falling and losing their energy, they return to their ground state releasing the measure of energy they absorbed in transitioning.
When light strikes a red object, the light waves of all colors except red are <em>absorbed</em> into the object, and never heard from again. <em> (B)</em>
The only thing left to bounce off of the object into anyone's eye is the waves of red.
Answer:
D (50m)
Explanation:
If distance is speed × time
That would be 5m/s × 10s
So the final answer will be 50m.

Answer:
A
Explanation:
A nonpolar molecule has no separation of charge, so no positive or negative poles are formed. In other words, the electrical charges of nonpolar molecules are evenly distributed across the molecule. Nonpolar molecules tend to dissolve well in nonpolar solvents, which are frequently organic solvents.
I want to say that the answer is either A or B but im not too sure. Im leaning more towards A tho
