Two asteroids orbit each other at a distance of 1.96 x 10 m. As they orbit each other, they each experience a gravitational force of 1.88 x 1011 N. One of the asteroids has a mass that is four times the mass of the other
asteroid.
Calculate the mass of the lighter asteroid.
PLEASE ANSWER QUICKLY

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:

the answer is mosques. they are an important part of islamic culture.

v=ir = 3x15 =45 v

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
