Line spectra are obtained when individual elements are heated using a high-voltage electrical discharge. This heating causes excitation of the element and a subsequent emission of distinct lines of colored light are obtained. Each element has its own unique emission line spectrum; therefore, if any of the tested substances were the same, their spectra would match. However, this is not the case so none of the substances are the same.
hope it helps!

Draw a circuit that contains 2 batteries, three lights in parallel and a switch that controls the whole circuit.
I think u can say thats a constant velocity, but remember if ur turning, or going around a curve, that is also changing velocity. Hope this helps have a great day!
Because you see yourself the opposite way in a mirror. So yes your “seeing” yourself but not how everyone else sees you.
