1. You dreg a crate across a floor with a rope. The force applied is 950 N and the angle of the rope is 32.0" above the horizontal. a. How much work do you do on the crate when moving it 22.0 m?
W-Fdcos (angle)

b. If you complete the job in 8.00 s, what power is developed?
P = W / t

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:

double the distance = divide strength by 4
