Given that the length of the bar (the rigid body studied) is 0.35 m, the hanging mass is 0.25 kg, and the angle of the string with respect to the rigid body (the radial line) is 45, determine the mass of the bar.

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:

no simpler subs form complex ones. synthesise = make
