Which of the following occurs as light travels farther from its source?
a. the source gives off less light as photons move away from it.
b. far from the source, photons spread over a larger area.
c. the intensity of light increases as photons move away from the source.
d. far from the source, photons come together in a small area.

  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
