What is the velocity of an object that has a momentum of 4,000 kg-m/s and a mass of 115 kg? round to the nearest hundredth.

a. 34.78 m/s
b. 36.5 m/s
c. 37.43 m/s
d. 35.67 m/s

Explanation:

The momentum is given by the following equation:

  (1)

Where:

is the mass of the object

is the velocity of the object

Finding the velocity from (1):

  (2)

Finally:

>>>This is the velocity of the object

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.

i would think it's food chain
