Sabiendo que la distancia media de la Tierra a la Luna es de 3,84 · 105 km, calcula: a) La fuerza con que se atraen la Tierra y la Luna. b) La aceleración que esa fuerza le comunica a la Luna y a la Tierra. Datos: mTierra = 5,97 · 1024 kg; mLuna = 7,35 · 1022 kg; G = 6,67 · 10-11 N·m2 /kg2

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:

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
