Two protons, starting several meters apart, are aimed directly at each other with speeds of 2.00 * 105 m> s, measured relative to the earth. find the maximum electric force that these protons will exert on each other

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

are their multiple choices ?

explanation:

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

so easy. just google the electromagnetic waves and it’ll pop up.
