Asun-sized star will spend most of its lifetime as a: white dwarf red giant protostar main-sequence star

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

(a) calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) imagine adding electrons to the pin until the negative charge has the very large value 1.00 mc. how many electrons are added for every 109 electrons already present
