Aparticle of mass m moves in the xy plane with a velocity of v = vxî + vyĵ. determine the angular momentum of the particle about the origin when its position vector is r = xî + yĵ. (use the following as necessary: x, y, vx, vy, and m.)

Explanation:

It is given that,

Velocity of a particle,

Position vector of a particle,

We need to find the angular momentum of the particle. It is given by :

, p = linear momentum

So, the angular momentum of the particle is . Hence, this is the required solution.

d. learned preferences i believe is your answer

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.
