A telewision weighs 8.50 pounds. How many grams is this? (Hint: You need to use two unit conversion fractions. 1 pound equals about 0.454 kg.)

3859 g

Explanation:

1 pound = 0.454 kg

therefore, 8.50 ponds = 0.454*8.50 = 3.859

to covert kilograms into grams you need to multiply it by 1000

=3.859*1000

= 3859 grams

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.
